Pirelli Scorpion Winter 2 vs Sottozero 3

Both Pirelli Scorpion Winter and the Pirelli Sottozero 3 are pretty decent options, each giving out unique abilities to conquer the toughest winter roads. But which one is better for you? Let’s find out?

Winter Tire — Both tires ready to be tested.

Key Takeaway

While both tires have their strengths, the Scorpion Winter 2 appears to have a slight edge in multiple areas based on the provided information.

Pirelli Scorpion Winter 2 excels in:

Wet Traction (Grip): Offers superior grip with its multi-angled sipes and combination of rectilinear and interlocking patterns, effectively extracting water for solid road contact.
Tread Life: Displays longer tread life due to its reduced weight, which results in decreased friction and slower rubber degradation.
Ice Performance: Features a superior average braking distance with its complex tread pattern, varied-width slanted cuts, and lighter construction aiding in easier stopping and better steering communication.
Comfort Levels (Noise): Produces lesser road noise, benefiting from its closed tread voids and a newer composition that reduces in-groove resonance.
Fuel Economy: Shows better fuel efficiency with its lighter weight, resulting in reduced rolling resistance and a more streamlined central rib for smoother tire rolling.

On the other hand, the Pirelli Winter Sottozero 3 (review) performs better in:

Wet Traction (and Aquaplaning Resistance): Demonstrates higher resistance to hydroplaning, attaining marginally higher speeds in both curved and straight aquaplaning tests due to its broader grooves.
Snow Performance: Shines in snowy conditions, particularly fluffy snow, with its open-designed lugs enhancing snow-to-snow contact and promoting better traction.
Comfort Levels (Vibration Absorption): Provides slightly better vibration damping, absorbing road irregularities more efficiently.

Wet Traction

Wet traction is chiefly dictated by two factors: grip, and resistance to hydroplaning or aquaplaning. In these regards, the tires display mixed performance.

For grip, the Pirelli Scorpion Winter 2 holds the advantage with its multi-angled sipes and a mixture of both rectilinear and interlocking patterns, as you can clearly see from its tread.

These orientations effectively extract water particles from the tire’s path, allowing for the tread blocks to secure solid contact with the road surface.

This phenomenon of sipes creating a vacuum and extracting water is central to their functionality.

In contrast, the Pirelli Sottozero 3 is equipped solely with laterally-oriented siping and lacks the rectilinear pattern of its competitor.

Therefore, it doesn’t quite match up in terms of grip, though it slightly surpasses the Scorpion Winter 2 in terms of aquaplaning resistance (the condition when a tire starts to float over water).

During testing, the Sottozero 3 demonstrated marginally higher speeds in both curved and straight aquaplaning tests, owing to its broader grooves that efficiently channel water away.

Therefore, the Pirelli Scorpion Winter 2 scores higher in grip, while the Pirelli Sottozero 3 leads in hydroplaning resistance.

Snow Performance

In varying snowy conditions, both tires showcase competitive performance, affirming their capabilities in navigating winter challenges. However, the Pirelli Sottozero 3 secures a slight lead, particularly when driving on somewhat fluffy snow terrain.

A close inspection of its tread pattern illuminates why. Despite having a directional tread pattern, its lugs present a more open design, promoting enhanced snow-to-snow contact.

The loosely packed snow is effortlessly gathered by the tire’s interlocking grooves and snow-catching recesses.

Once trapped, the snow creates a snowy interface between the tire and the ground, providing superior traction due to the enhanced adherence of snow to snow compared to snow to rubber.

Conversely, the Pirelli Scorpion Winter 2’s tread appears more enclosed, forming a continuous running rib at its core and lacking the interlocking groove configuration.

Consequently, its tread doesn’t pick up as much snow, falling slightly short of its competitor.

Therefore, while the Pirelli Scorpion Winter 2 excels on ice, the Pirelli Sottozero 3 shines brighter on snowy terrain.

Tread Life

The lifespan of a tire’s tread is significantly influenced by its rolling resistance. In this regard, the Scorpion Winter 2 outperforms the Sottozero 3.

The reduced weight of the tire lessens the force exerted by its blocks on the road surface, leading to decreased friction and slower overall rubber degradation.

Conversely, the heavier Pirelli Sottozero 3 not only exerts more force due to its weight but also due to its broader tread voids, concentrating this additional weight onto a smaller rubber surface.

This results in each lug bearing more weight, contributing to faster tread wear and potentially reducing the tire’s lifespan.

However, the disparity in performance between the two tires isn’t vast, which may explain why neither brand offers warranties.

Thus, the Scorpion Winter 2 comes out on top regarding tread life.

Ice Performance

When operating under icy conditions, the performance of the Pirelli Scorpion Winter 2 becomes noticeable, presenting a superior average braking distance, (as seen on tests, averaged, of course).

But why?

If you consider its tread pattern again, you’d find your answer.

Its multiple complex tread biter, where you get varied-width slanted cuts, multiple notches, and a lot of sipes, all contributing to a notable grip under icy conditions.

These biters also multiple angles, further adding to the grip and thus contributing to the efficient braking and handling performance of the tire.

Though still, the major reason why its performance is better is its lighter construction.

Technically speaking, the tire’s lighter build basically allows for a relatively smaller momentum, as the tire maneuvers. This leads to easier stopping and greater communication of the steering.

So overall ice grip performance is seen better on Scorpion Winter 2.

Comfort Levels

Comfort in a tire relies on factors such as road noise and vibration absorption, all of which are influenced by the tire’s design, incorporated materials, tread pattern, and sidewall structure.

Now out of them, road noise primarily originates from collisions of air particles with the tread walls. And in this regard, the Pirelli Scorpion Winter 2, with its relatively closed tread voids, delivers marginally superior performance.

Moreover, the tire also has the edge of its new generation composition, which doesn’t create as much in-groove resonance as seen its counterpart.

Speaking of which, the Pirelli Sottozero 3 provides slightly better vibration damping, offering enhanced absorption over road irregularities.

That’s why with each tire better in these respective performance sections, both tires get the same overall scores, (as concluded through my subjective testing with them).

Fuel Economy

Fuel economy is affected by the tire’s contact with the road and its overall structural weight. And here, the Pirelli Scorpion Winter 2, with its lighter weight, demonstrates better performance in this context.

With less weight, the lugs of the tire experience less pressure against the road, resulting in lower rolling resistance values. Furthermore, this tire exhibits a more streamlined central rib compared to its counterpart, facilitating smoother tire rolling.

In contrast, the Pirelli Sottozero 3, with slightly greater weight, exhibits elevated rolling resistance.

This increased weight results in the tire lugs bending more during maneuvers such as cornering, leading to heat generation and energy wastage, which could have otherwise contributed to tire rolling.

Though the difference is very low, as Sottozero still resist its lug bending with its slightly more rigid tread composition.

But yes, overall, Scorpion Winter 2 leads here.

To Conclude

When evaluating both tires, their performances in varied conditions differ.

In wet conditions, Scorpion Winter 2 dominates in grip, thanks to its multi-angled sipes and varied tread patterns. However, its counterpart proves superior in resisting aquaplaning due to its broader grooves.

On snowy terrains, Sottozero 3’s open lug design offers better snow-to-snow contact, granting it a slight advantage. Though the tire lacks on ice.

In terms of tread life, Scorpion Winter 2 outshines because of its reduced weight and diminished rolling resistance, which also results in the tire giving off better fuel economy.

Lastly both tires offer similar scores when it comes to comfort performance.

Pirelli Winter Sottozero 3 vs Michelin Pilot Alpin PA4

Pirelli Winter Sottozero 3, celebrated for its impressive performance in snowy conditions, and Michelin Pilot Alpin PA4, known for its superior handling on ice, are up for a duel. Let’s see which winter tire claims victory!

Key Takeaway

Michelin Pilot Alpin PA4 excels in:

Snow Performance: Due to broader grooves for optimized snow-to-snow contact. And since snow sticks better on snow, instead of rubber, that enhances overall friction, better, relatively.
Hydroplaning Resistance: Thanks to its wider grooves for efficient water dispersion, where its heavier weight also help creating greater negative pressure values.
Comfort Levels: The tire offers better vibration absorption due to absorbent tread rubber and increased tread depth. (Greater the depth of rubber, more the cushion for the road vibrations).

Pirelli Winter Sottozero 3 stands out for:

Wet Grip: Where streamlined lugs for better handling performance, as they offer superior steering response in comparison.
Tread Longevity: Where lighter weight puts less pressure on lugs, resulting in less friction against the road.
Fuel Economy: Where the tire’s streamlined tread design reduce rolling resistance, achieving better mpg.
Comfort Levels: The tire reduces road noise with compact shoulder lugs and densely packed central design.

Tire Sizes

On the other side, the Pirelli Winter Sottozero 3 (review) comes in 16 to 21 inches with following specs.

Speed ratings: H, V and W.
Load ratings: SL and XL.
Tread depth: 10/32″ on all.
Weight: 18 to 32 lbs.

On the other side, the Michelin Pilot Alpin PA4 (review) comes in 51 total sizes in 17 to 21 inches (with following specs).

Speed ratings: H, V and W.
Load ratings: SL and XL.
Tread depth: 10.5/32″ on all.
Weight: 10 to 36 lbs.
Tread warranty: 30k miles (whereas the Pirelli doesn’t offer any).

Snow Performance

When it comes to snowy terrains, the Michelin Pilot Alpin PA4 outperforms its competitor.

But why is that happening?

In snowy conditions, tires that optimize snow-to-snow contact tend to excel. And the Michelin, with its broader grooves, fits this criterion perfectly.

It features a symmetric tread adorned with a myriad of triangular-shaped lugs, equipped with in-groove notches that effectively capture snow particles.

This design results in a layer of entrapped snow that interacts with the snowy terrain, thereby enhancing traction.

Snow-to-snow interaction is favored since snow particles adhere more effectively to each other than to rubber.

In contrast, the Pirelli Winter Sottozero 3, with its denser pattern, fails to accumulate as much snow within its grooves, thereby lacking in this area.

While the discrepancy in directional grip and acceleration is significant, the variation in handling is minimal and subjectively feels identical. Thus, on snowy terrain, the Michelin Pilot Alpin PA4 reigns supreme.

Wet Traction

Tire performance on wet surfaces is critically dependent on the tread design and rubber compound. These components influence the tire’s ability to grip wet roads and resist hydroplaning.

Let’s check out both of these one after another, starting with the grip.

Wet Grip

So overall grip highly depends on sipes. These are slits which suck up water, clearing off the road. That way, the rubber is able to properly grip the surface, and there’s no water in between.

Although both models feature substantial siping and flexible tread rubber, the Pirelli Winter Sottozero 3 outperforms, in terms of grip.

This advantage is more noticeable in handling performance, a significant factor in traction

The tire’s advanced water channeling capabilities, facilitated by its multi-angled sipes and notches directed in various ways, ensure grip in all directions while cornering and minimal slippage.

On the other hand, the Michelin, with its laterally-oriented sipes on the shoulders, resulted in slower overall handling times during tests.

Though most of the damage here is done by the tire’s greater weight. This is because with greater overall structure, the tire puts more pressure on it lugs, and this creates greater overall momentum for this tire.

This means, it’s not as easier to stop, in comparison, and during handling, there’s less overall steering balance.

So overall, the wet traction is superior on Pirelli.

Hydroplaning

Hydroplaning is a key safety concern, manifesting when water interferes with the tread’s contact with the road, leading to the tire ‘floating’ and losing traction.

Among the two, the Michelin Pilot Alpin PA4 outperforms in this aspect, with its wider grooves enabling efficient water dispersion in all directions.

And tire’s greater weight is helping to that, surprisingly, (even though it also causes its steering to be sluggish).

So what’s happening here? Well two things:

The tire’s greater weight is actually because of its greater tread depth, and that combined with its more voided up structure, you get faster water evacuation, leading to improved float speeds.
As the tire’s greater weight is pushing lugs down, more, the create a better negative pressure (as water is not compressible). So it gushes out with faster speeds.

Contrarily, the Winter Sottozero 3’s compacted up central rib (even though having lateral voids), hampers water movement, particularly laterally, due to the lack of better interconnected lugs.

So overall while the Pirelli’s tire only offers superior wet grip, while Michelin gives you greater resistance to hydro or aquaplaning.

Tread Longevity

When it comes to tread longevity, you should know that it’s predominantly governed by the pivotal concept of rolling resistance, combined with the tire’s tread depth.

Now the irony here is that tread depth is inversely proportional to rolling resistance, though its directly proportional to tread life.

Meaning, with more tread life, a tire would cover more miles to reach the legal minimum tread depth of 2/32″, which is a mandated limit for driving in certain regions such as the United States.

Though at the same time, with greater tread depth, lugs also become prone to bending, and that causes heat and increase in rolling resistance.

Now although the Michelin tire comes with a slightly greater tread depth it’s greater weight, puts it behind its competitor.

Where the Pirelli Winter Sottozero 3, despite demonstrating a lesser degree of durability compared to other options, excels in rendering an outstanding tread life.

Its relatively featherweight stature imparts reduced pressure on its lugs, leading to a diminished rub against the abrasive asphalt, ultimately promoting an extended tread existence.

And Pilot Alpin PA4, imposing/stressing more substantial pressure on its lugs, which subsequently rub against the road surface with greater friction, results with an accelerated wear rate.

So even though the Michelin’s tire comes with a treadwear warranty (of 30k miles), unlike the Pirelli, it still lacks in overall tread life performance.

Comfort Levels

Tire comfort is predominantly dictated by two factors – the level of road noise and the tire’s capacity to absorb vibrations. Both these aspects are heavily dependent on the tire’s design.

The Pirelli Winter Sottozero 3 excels in minimizing road noise owing to its compact shoulder lugs and densely packed central design.

These features limit air movement and subsequently reduce noise generation.

Furthermore, it employs advanced pitch sequencing to further mitigate any residual noise, ensuring a more tranquil ride compared to Michelin.

Speaking of which, the Pilot Alpin PA4 demonstrates superior vibration absorption capabilities, and since that is also a factor here in overall ride comfort, you get better scores in terms of impact comfort, with this tire.

This is due to its more absorbent tread rubber and increased tread depth, which collectively enable superior shock absorption.

So to sum up here, the Pirelli is quieter, while the Michelin offers better ride over bumps.

Fuel Economy

Fuel efficiency in tires is directly related to their weight and traction, both of which influence rolling resistance.

Specifically, a heavier tire with expansive tread voids tends to experience more lug flexing during activities like cornering, braking, or accelerating.

This flexing consumes additional energy, a trait prominently observed in the Michelin’s tire.

As the lugs flex, energy predominantly dissipates as heat, which not only impacts tread longevity but also amplifies the tire’s rolling resistance.

And our tests corroborate this assessment.

That’s why Pirelli Winter Sottozero 3, with lighter weight is taking the lead here.

Moreover, the tire also has the advantage of it’s tread design, where there are more streamlined and longitudinally oriented ribs, minimizes rolling resistance and thus delivers enhanced fuel efficiency.

So simply put, with the Pirelli, you get to achieve more miles per gallon.

Summing Up

So overall, here, the ideal choice depends on individual priorities, as both tires have their pros and cons.

When navigating snowy terrains, the Pilot Alpin PA4 clearly takes the lead due to its design favoring snow-to-snow interaction, which ensures enhanced traction. However, on wet surfaces, the Winter Sottozero 3 showcases superior wet grip, while its counterpart has an edge in resisting hydroplaning, thanks to its effective water dispersion capabilities.

In the realm of tread longevity, Pirelli outshines with an impressive tread life, attributed to its lightweight design, despite its competitor having a treadwear warranty. Moreover, the tire also excels in fuel economy, offering better mileage per gallon due to its efficient design minimizing rolling resistance.

Lastly, in the comfort arena, the Michelin provides a smoother journey over uneven terrains with its superior shock absorption, though it’s not as quiet on roads, in comparison.

Pirelli Scorpion Winter vs Ice Zero FR

The competition is on as Pirelli Scorpion Winter, noted for its comfort and durability, challenges Pirelli Ice Zero FR, hailed for its fantastic handling. Let’s uncover which tire will dominate the winter roads!

Fuel Usage

Fuel efficiency in tires is fundamentally linked to tread design and structural weight as these elements determine the rolling resistance, which directly affects fuel consumption.

In this aspect, both tires showcase similar levels.

Although the Pirelli Ice Zero FR flaunts a lighter overall structure (averaged across all sizes), it has slightly wider tread voids which instigate additional lug movement during maneuvers, requiring extra fuel consumption.

However, this effect is counterbalanced by the Pirelli Scorpion Winter, which, despite its heavier weight applying more pressure on the lugs, results in similar levels of fuel consumption.

Consequently, in terms of fuel economy, it’s a deadlock between the two tires.

Tread Life

The lifespan of a tire’s tread is an amalgamation of various factors such as the tire’s weight, the depth of the tread, its design, and the makeup of its compound. And considering these variables, it’s not surprising to see the Pirelli Ice Zero FR outshining others in this facet.

The Pirelli Ice Zero FR carries a lighter weight, which means each of its individual lugs are subjected to lesser pressure, resulting in minimized friction as they interact with the road’s surface.

And adding to this, the tire features enhanced tread depth. (This quality is advantageous as the deeper the tread voids, the more time it will require for the tire to wear down to its replacement stage).

On the contrary, while the Pirelli Scorpion Winter profits from a somewhat sturdier tread compound that fights against wear, its overall tread life still falls short when juxtaposed with the Pirelli Ice Zero FR.

Comfort Levels

Ride comfort can be essentially boiled down to the reduction of noise and the tire’s ability to absorb shocks from the road.

Discussing noise first, it’s primarily generated when air particles collide with the walls of the tread. In simpler terms, larger tread gaps tend to give rise to a noisier tire.

In this respect, the Pirelli Scorpion Winter enjoys an advantage with its more compact design.

Moreover, the tire employs a superior pitch sequencing technology where alterations in the tread block geometry induce the creation of different tones by air particles. These tones then cancel each other out, leading to a reduction in noise.

On the other hand, the Pirelli Ice Zero FR excels in quelling vibrations, owing to its softer overall tread compound.

Its relatively supple tread composition boosts its shock-absorbing capabilities, assuring a smoother ride.

Thus, while the Pirelli Ice Zero FR offers superior performance in terms of impact comfort, the Pirelli Scorpion Winter renders a quieter ride, with each tire shining in their respective comfort zones.

Fluffy Snow Traction

In conditions of soft snowy landscapes, the Pirelli Scorpion Winter manages to notch ahead slightly, and it accomplishes this, through its expansive assortment of gaps or biters that act as snow traps.

These snow traps foster a robust snow-to-snow bond, which forms the tire’s contact patch with the ground, thus enhancing traction. This effect stems from the fact that snow adheres more effectively to itself than it does to rubber.

In comparison, the Pirelli Ice Zero FR lacks these particular attributes.

Although its tread pattern is also directional, it misses the sleek effect of the Pirelli Scorpion Winter, diminishing its effectiveness in ejecting snow to create forward thrust.

Additionally, a closer examination of its tread reveals that it doesn’t possess as many interconnected tread voids as its rival, leading to less efficient snow-to-snow contact.

Wet Grip

Upon testing, both tires exhibit similar wet braking distances (calculated on average), implying comparable grip levels. However, when it comes to handling, the Pirelli Ice Zero FR slightly outshines its counterpart.

This advantage is primarily due to the tire’s superior water clearance capabilities, credited to its multi-angled sipes and notches, which are facing both lateral and longitudinal directions on the tread. This design facilitates grip in all directions when cornering, minimizing the risk of slippage.

In contrast, the Pirelli Scorpion Winter, which only has laterally oriented sipes on its shoulders, shows a deficiency in overall handling times during testing.

Dry Traction

The overall dry performance of a tire depends on two aspects, directional grip, and handling.

Directional grip’s effectiveness predominantly lies in the central region of the tread, and it makes sense why the Scorpion Winter with more closed up pattern there offer better overall efficacy.

Even though both tires are equipped with robust foundations underneath the central lugs, the Scorpion Winter still manages to provide greater rubber to road contact, resulting in a remarkable 4 feet reduction in average braking distance in tests compared to the Pirelli Ice Zero FR.

Though the opposite happens, when the handling is considered, which relies primarily on the tire’s shoulder design and total weight.

Here, the Pirelli Scorpion Winter having a heftier structural weight is at a disadvantage.

Its greater weight induces increased lug movement during cornering, thereby compromising steering feedback.

On the contrary, the lighter Pirelli Ice Zero FR ensures a more harmonious balance between understeering and oversteering, enhancing overall steering responsiveness.

Ice Traction

In icy conditions, the Pirelli Ice Zero FR holds the upper hand, as it offers more biters per surface area of its tread, including an array of various sipes, and multi-angled notches.

This allows the tire to brake 4 feet faster, on average.

Conversely, the Pirelli Scorpion Winter, although featuring plenty of in-groove notches, lacks an aggressive siping design.

And yes, it rubber is also not that flexible as well, so all its biters don’t get to grip on ice with as much efficacy as seen on its counterpart.

Summing Up

So, what are the key takeaways?

Evidently, each tire excels in distinct areas.

The Pirelli Scorpion Winter shines on snowy terrain due to its extensive snow traps and streamlined tread design, providing superior snow traction. Plus, this tire offers better directional traction on both wet and dry roads

Conversely, the Pirelli Ice Zero FR outperforms in icy conditions due to its specialized biters and comprehensive grip from multiple angles. And this tire features superior handling capabilities in both wet and dry.

In terms of treadwear, the Pirelli Ice Zero FR comes out better, offering longer tread life.

And fuel economy is almost similar on both.

Pirelli Winter Sottozero 3 vs SottoZero 2

Both Pirelli Winter Sottozero 3 and SottoZero 2 are trusted allies when battling winter’s wrath, each offering unique weapons to combat icy roads and snowy paths. As winter approaches, let’s find out which ally stands strongest!

Quick Takeaway

Pirelli Winter Sottozero 3 (review) performs better in:

Tread Wear: This tire features a lighter construction, putting less strain on the tire lugs during motion, hence prolonging its functional life.
Ice Performance: With advanced design elements, the Sottozero 3 offers superior traction and handling in icy conditions.
Wet Traction: It provides superior wet handling due to its enhanced water expulsion capabilities and effective siping, resulting in shorter braking distances.
Dry Traction (Directional Grip): With a more streamlined design and interlocking central lugs, this tire offers greater rubber-to-road contact and superior performance.
Handling: Compact shoulder blocks and lighter structure ensure balanced understeering and oversteering capabilities.
Tread Noise: Due to densely packed shoulder lugs and interlocking central lugs, this tire produces lower levels of noise.

Pirelli Winter Sottozero 2 performs better in:

Snow Performance: Engineered grooves on this tire provide better snow-to-snow contact, offering superior friction and grip.
On-Road Vibration: This tire offers superior impact comfort due to its more absorbent tread rubber and greater tread depth.

TreadWear

The longevity of tread, (largely influenced by the degree of rolling resistance), is a critical performance parameter where both tires demonstrate equivalent effectiveness.

Though still if you really have to pick one here, I’d say go with Pirelli Winter Sottozero 3, as the tire features a relatively lighter construction, exerting reduced strain on the tire lugs during motion, which effectively prolongs its functional life, a little more, comparatively.

The Sottozero 2 on the other hand, featuring less innovative tread compound is not as elastic, so it reaches the 2/32″ of tread depth limit faster.

Ice Performance

The Pirelli Winter Sottozero 3 exhibits superior performance under icy conditions, as its advanced design elements, including unique biters dispersed throughout the tread and augmented by snow vices, yield marginally superior overall traction.

This innovative design, bolstered by multi-directional siping and snow vices, results in enhanced braking responsiveness and handling effectiveness across various snowy conditions.

In contrast, the Pirelli Winter Sottozero 2, though featuring multi-directional biters, fails to compete adequately. Its wider biters reduce efficiency on compacted ice where more aggressive, narrow siping is preferred, making it better suited for larger vehicles like SUVs due to its more extensive tread voids.

Wet Traction

Two primary elements influence wet traction performance: the tread design and the rubber compound, as together, they determine the tire’s ability to eliminate water (basically with the help of sipes and grooves).

Majority of water is removed with grooves, so these contribute to the hydroplaning renaissance the most, while the remaining left over water is dealt with sipes, which translate in to what we call wet grip.

Let’s discuss both in more details.

Now in terms of grip, the Pirelli Winter Sottozero 3 presents a slight advantage in wet handling due to its enhanced water expulsion capabilities (through its more effective siping).

These sipes are multi-angled and work along side the tire’s numerous other biters and overall asymmetric tread design to provide you with overall 4 feet shorter braking distances, and faster handling times on average.

In contrast, the Pirelli Winter Sottozero 2 does not offer as aggressive of the overall tread pattern, and it’s closed up tread design is also not so well designed when it comes to hydroplaning as well.

Hydroplaning is a condition, which is characterized by the disruption of tread contact with the road due to water interference. In simpler words, it’s when a tire starts to float.

And here the Sottozero 3 with wider grooves, offer a more effective dispersing of water, and in multiple directions too. So you get slightly better float speeds in both curved and linear aqua tests.

Snow Performance

Snow has a lot of types, but still two of them are the most important ones, there’s ice, and then there’s soft/fluffy snow.

And although the Pirelli Winter Sottozero 2 is overall lacking, when it comes to ice, the tire outperforms its updated version, thanks to it’s well engineered grooves, which provide better snow to snow contact.

This type of contact, basically offers better friction and overall grip, as snow adheres better to itself than to rubber.

The Sottozero 3 in comparison, is lacking here, as the tire struggles to accumulate a comparable amount of snow.

Dry Traction

Dry traction serves as a crucial performance metric for any tire, with its measure primarily contingent upon the quantity of rubber establishing contact with the road surface.

And this brings us to two pivotal elements here, directional grip and lateral traction. Let’s start with grip.

Directional Grip

The effectiveness of directional grip is largely reliant on the tire tread’s central region.

This correlation emerges from the fact that, as the tire rolls straight, the central most area is what bears the most weight pressure upon itself.

That’s why it makes sense why out of both tires, with a more streamlined design, the Pirelli Winter Sottozero 3 emerges superior.

The tire features interlocking central lugs, which offer greater rubber to road contact, and as these lugs are also backed up by powerful reinforced foundations, you get superior overall performance here, as showed by its average braking distance values on tests.

In contrast, the Winter Sottozero 2 doesn’t perform quite as well due to its broader grooves and less aerodynamically streamlined structure, which result in braking distances extending approximately five feet longer.

Handling

The caliber of tire handling is significantly determined by the shoulder design and overall weight of the tire. This is due to the inertia-induced weight shifting towards the tread edges during cornering.

And here, once again the Sottozero 3 seems to take the upper hand. But why? Well, because of two main reasons.

First, the tire’s compact shoulder blocks significantly enhance the level of rubber-to-road contact.

And second, the combination of the tire’s lighter structure and shallower tread depth restricts lug movement (or block bending) during cornering, thus ensuring balanced understeering and oversteering capabilities.

The Sottozero 2 on the other hand, lacks behind as it’s missing with both of these features mentioned above.

Comfort Levels

The degree of comfort furnished by a tire is substantially dependent on two factors: its level of noise generation and its ability to dampen vibrations.

Let’s examine each of these elements more closely.

Tread Noise

Tread noise typically originates from the collision of air particles with the tread walls of the tire.

So to put simply, larger tread voids tend to create a higher level of noise.

That’s why when comparing, the Pirelli Winter Sottozero 3 emerges as a quieter option, attributed to its densely packed shoulder lugs, the primary entry point for air.

Moreover, the tire’s interlocking lugs in the middle further dampen down the noise levels, as they vary slightly form one other in geometry.

This basically produces different sets of tones as air particles collide them, and those try to cancel out each other.

On-Road Vibration

While the Pirelli Winter Sottozero 2 may generate more noise, it outperforms its counterpart in the aspect of dampening road vibrations, thus offering superior impact comfort.

And this can be attributed to the more absorbent tread rubber and greater tread depth, which together provide a thicker buffer layer between the tire and any road surface irregularities.

Summing Up

After an extensive comparison, it’s clear that both Pirelli Winter Sottozero 3 and Sottozero 2 come with their respective strengths and weaknesses. Despite their shared manufacturer, the two tires diverge quite a bit in terms of specific performance categories.

The Sottozero 3 particularly shines in longevity, with a slightly longer tread life, and in ice, wet and dry performance, providing superior traction and handling capabilities, thanks to its innovative design, multi-directional siping, and larger tread voids. It also has an edge in comfort, proving to be the quieter option due to its densely packed shoulder lugs and varying geometry interlocking lugs, which work together to mitigate noise.

In contrast, the Sottozero 2, though lacking in several areas compared to its updated counterpart, shows its mettle in terms of snow performance and on-road vibration damping. Its well-engineered grooves allow better snow-to-snow contact, enhancing friction and overall grip, while its more absorbent tread rubber and greater tread depth ensure superior impact comfort by buffering against road surface irregularities.

Pirelli P Zero Winter vs Michelin Pilot Alpin 5

As the winter season looms, Pirelli P Zero Winter and Michelin Pilot Alpin 5, both showcasing unique expertise in handling and comfort, provide an array of options for different driving styles. But who will win this winter showdown? Well, let’s find out!

Key Takeaway

The Pirelli P Zero Winter stands out when it comes to:

Fuel Economy: The tire’s streamlined longitudinal ribs generate lower rolling resistance values, thus improving energy efficiency and contributing to better fuel economy.
Ice Performance: The Pirelli shows remarkable performance on icy terrains, delivering shorter average braking distances, due to its detailed biters and an array of slanted incisions.
Dry Traction: The longitudinal ribs of this tire ensure superior lug-to-road connectivity, resulting in shorter braking distances and improved directional grip.
Wet Grip: With its multi-angled siping pattern of varied thickness, the P Zero Winter delivers improved overall grip in wet conditions, resulting in shorter braking distances and better lateral traction.

However, the Michelin Pilot Alpin 5 excels in:

Fluffy Snow Performance: The Michelin provides superior traction on fluffy snow terrains thanks to its unique and slightly more aggressive tread pattern. It efficiently captures and retains fluffy snow particles within its interlocking grooves and snow vices, leading to increased friction and better performance.
Hydroplaning: The tire’s directional tread pattern, along with its longitudinal running central most channel, effectively displaces water, reducing the risk of hydroplaning and improving performance in wet conditions.

Fuel Economy

The efficiency of fuel consumption is intrinsically linked to the tire’s traction attributes and comprehensive weight – two domains where the Michelin Pilot Alpin 5 displays room for potential enhancements.

This tire’s escalated weight and expansive tread voids propagate increased lug flexing during cornering, braking, and acceleration activities.

It’s greater weight, distributed over a relatively smaller surface area bears a more intensified pressure on the lugs, causing them to bend or mold, consequently, asking for additional energy expenditure.

This energy that’s spent bending the lugs, could otherwise be used in to the rolling of the tire.

That’s why in comparison, the Pirelli P Zero Winter is doing better with it’s relatively more streamlined longitudinal ribs, generating lower rolling resistance values.

In other words, the lugs on this tire aren’t compelled to rub against the road with the same degree of force. The compact tread structure concentrates energy on propelling the entire tire, rather than bending individual blocks, leading to superior energy efficiency.

Ice Performance

Under icy conditions, the Pirelli P Zero Winter boldly asserts its dominance, with an average (7 feet shorter) braking distance compared to its competitor.

So why is the Michelin Pilot Alpin 5 lacking here?

Well, this deficiency can be attributed to the tire’s larger tread voids and fewer notches, which render it less equipped to handle icy conditions.

The central tread area, a crucial component for braking, grapples with gripping packed ice due to the wider lateral tread voids.

Moreover, you also don’t get as aggressive of the overall siping as seen on its counterpart.

On the contrary, the P Zero Winter trumps the competition with its detailed biters spread across the tread.

The tire’s asymmetric pattern combined with a wide array of slanted incisions, combined with multi-angled siping, all contribute to it’s better overall icy terrain performance.

Dry Traction

Dry traction is essentially about the degree of rubber contact with the road, with directional grip and lateral traction playing indispensable roles. Let’s discuss each of these factors in detail.

Directional Grip

The performance of directional grip hinges largely on the central section of the tread. This is because when the tire rolls straight, such as on highways, the majority of the weight it carries concentrates in the central region.

Here, the Pirelli’s longitudinal ribs offer superior lug-to-road connectivity, culminating in shorter braking distances compared to its competitor (a direct measure of directional grip, for the uninitiated).

Conversely, with a directional pattern that includes wider lateral tread voids, (referring to central most circumferential channel), the longitudinal movement of the tread is somewhat restricted, leading to extended braking times.

Handling

Handling performance is primarily influenced by the tire’s shoulder regions and overall weight. As the tire corners, the weight shifts towards the edges of the tread (or shoulders), making their contact with the ground critical.

In this context, the Michelin Pilot Alpin 5, characterized by wider grooves, doesn’t quite meet the performance demonstrated by its counterpart.

Moreover, the additional weight of the tire further compromises overall performance.

This extra weight instigates increased lug movement as the tire maneuvers corners, consequently diminishing steering feedback.

Wet Traction

The performance of a tire in wet conditions is primarily dictated by two pivotal factors: the tread design and the specific rubber compound used in the tire’s construction.

These elements subsequently determine the tire’s grip on wet surfaces and its ability to resist hydroplaning. Let’s start with hydroplaning.

Hydroplaning

Hydroplaning is a phenomenon that occurs when water obstructs the tire tread to properly contact the road. And needless to say, this results in the tire skimming over the water and losing all traction.

And here, the Michelin Pilot has the advantage of having a directional tread pattern with swooping arms, along with longitudinal running central most channel.

Both work in harmony to throw water away from the tread, as it leave out laterally (for the most part), more efficiently.

Here, the Pirelli P Zero Winter, lacks with it’s longitudinal ribs, restricts efficient sideways water displacement, falling behind compared to its competitor.

That’s why although both tires show up with similar straight float speeds, the Pirelli lacks on curved aquaplaning tests.

Wet Grip

Although both tires are fortified with an abundance of siping, given they are winter tires, the Pirelli’s boy still takes away a larger piece of the pie.

This is because wet grip is not just about the number of sipes, but also the type/design too.

And in this regard, with Pirelli adopting multi-angled siping pattern of varied thickness, the tire offers better overall grip, and in all directions too, I should add.

That’s why it features shorter braking distances and lateral traction overall, (as calculated by g forces).

On the other hand, the Michelin Pilot Alpin 5, equipped solely with laterally oriented sipes, slightly under-performs in delivering comprehensive traction. To put simply, this tire lacks because it’s siping isn’t relatively aggressive enough.

Fluffy Snow Performance

When faced with a snowy landscape, both tires exhibit commendable performance. However, if one were to make a choice, the Michelin Pilot Alpin 5 would be the preferred option, especially for navigating fluffier snow terrains.

This superior traction is largely attributed to its unique tread design. The tire features a slightly more aggressive tread pattern with lugs that are spaced apart to interact with the snowy surface effectively.

These tread blocks then establish a snow-to-snow contact, as they efficiently capture and retain fluffy snow particles within their interlocking grooves and snow vices.

This process creates a layer of trapped snow that helps the tread maintain ground contact through this snowy buffer.

Since snow bonds better with itself than with rubber, this results in increased friction.

On the other side, the Pirelli P zero lacks with it’s tighter grooves, and missing swooping arms. So it can’t offer ample snow to snow contact, nor its able to as effectively paddle on this snowy terrain type.

Summing Up

Let’s take it home.

The Michelin Pilot Alpin 5 shines in soft/fluffy snowy conditions due to its distinctive tread design and larger number of tread voids, delivering exceptional snow grip and clearance capabilities. However, when navigating icy terrains, the Pirelli P Zero Winter stands out.

This is because this tire has more biting edges, highly needed on icy terrain traction. And these very biters also help the tire on wet roads.

The same holds true when evaluating dry traction, fuel economy, and tread life, where the Pirelli P Zero Winter comes out on top.
