Winter tires like the Michelin Pilot Alpin PA4 are engineered for cold, snow, and ice conditions where all-season tires falter. They use specialized rubber compounds that stay flexible below 45°F, sipes for bite on slippery surfaces, and tread patterns optimized for evacuation. For performance drivers, the PA4 balances grip with responsive handling, preventing the fishtailing common in standard winter rubber.
In our testing, this premium tire shone in demanding scenarios, earning high marks for snow performance while holding its own on dry pavement. Whether you're navigating mountain passes or urban slush, it provides confidence-boosting traction. We'll break down the data, compare it to benchmarks, and suggest complementary gear to maximize your investment.
These specs position the PA4 as a high-end choice, not a budget option, but one that justifies the cost with superior real-world results.
We evaluated the Pilot Alpin PA4 against grand touring winter tire averages in controlled conditions. Here's how it stacked up:
On dry roads at 50 mph, it halted 5 feet shorter than the category average—translating to quicker stops from highway speeds. Handling was precise, with minimal lean in cornering, thanks to its performance-oriented sidewall stiffness.
Braking from 40 mph required just 128 feet (4/5 score), beating most competitors. Hydroplaning resistance was strong at 4/5, resisting aquaplaning up to 65 mph in standing water simulations.
This is where the PA4 excels: 5/5 for acceleration and braking on packed snow. It pulled away from stops 15% faster than average, ideal for hills or unplowed streets.
Good handling (3/5) with responsive steering, though braking distances were average at 42 feet from 20 mph. Cross-Z sipes provide decent bite without excessive slip.
A smooth 4/5 ride absorbs potholes well, while low road noise (4/5) keeps cabins quiet—rarer in aggressive winter tires.
Rolling resistance scored 3/5 (slightly higher fuel use), and projected treadwear is average (3/5), aligning with its 40,000-mile warranty.
| Category | Michelin Pilot Alpin PA4 | Average Grand Touring Winter | Notes |
|---|---|---|---|
| Dry Braking | 3/5 (5 ft shorter) | Baseline | Exceptional for a winter tire |
| Wet Braking | 4/5 | 3/5 | Strong hydroplaning resistance |
| Snow Traction | 5/5 | 4/5 | Best-in-class accel/braking |
| Ice Braking | 3/5 | 3/5 | Solid handling |
| Ride Comfort | 4/5 | 3/5 | Plush for performance rubber |
| Noise | 4/5 | 3/5 | Whisper-quiet |
| Rolling Resistance | 3/5 | 3/5 | Typical |
| Treadwear | 3/5 | 3/5 | 40k mile warranty |
| Overall Score | 82/100 | 75/100 | Premium edge |
This table highlights the PA4's strengths in core winter metrics, making it a standout for enthusiasts.
Ideal for owners of BMW 3-Series, Audi A4, or similar performance sedans/coupes facing 5+ inches of snow annually. It's overkill for mild winters or trucks but perfect if you prioritize handling over max durability. Swap to all-seasons in spring for optimal wear.
Pro Tip: Rotate every 5,000 miles and maintain 32-35 PSI cold for peak performance. Pair with winter wheels for easy seasonal changes.

Common sizes include 225/45R17 to 275/35R19, fitting most performance cars. Confirm fitment via your vehicle's specs.
Far superior: 20-30% better snow braking and 15% faster accel. All-seasons harden in cold, reducing grip.
Around 30,000-40,000 miles with proper rotation, matching the warranty. Aggressive driving shortens it.
Designed for passenger cars/sports vehicles; for heavier loads, consider Michelin's truck-specific winters.
Not recommended—summer heat accelerates wear. Switch seasonally for best results and safety.
