Michelin Pilot Sport A/S 4 Product Description

This listing is for new Michelin Pilot Sport A/S 4 275/50R20XL 113Y BSW Tires. Manufacturer part number: 26900.

The Michelin Pilot Sport A/S 4 is an ultra-high-performance (UHP) all-season tire and one of the defining benchmarks of its category. Engineered for sports cars, performance sedans, and high-output crossovers, it delivers near-summer cornering response and high-speed braking while maintaining year-round usability in cold climates. Backed by a UTQG rating of 540 A A and a 45,000-mile limited treadwear warranty, it offers exceptional mileage longevity for a tire in this grip tier.

The tire combines an asymmetric tread design with Michelin’s race-derived Extreme Silica+ compound to maximize lateral cornering contact and maintain wet braking leadership. For winter versatility, Helio+ compound technology uses sunflower oil to keep the rubber pliable at temperatures below 45°F, while 360-degree variable 3D sipe technology provides multidirectional biting edges for rain and slush without allowing tread block squirm during aggressive dry cornering. Specially designed groove edges trap loose snow to leverage snow-on-snow friction for added control on chilly morning pavement.

The decision matrix against its summer sibling, the Pilot Sport 4S, is straightforward:

• Choose the Pilot Sport 4S if your vehicle is driven exclusively in warm, dry/wet conditions or stored during winter.

• Choose the Pilot Sport A/S 4 if your vehicle is a daily driver that must operate safely through late fall, winter cold, and early spring.

As a performance all-season tire, it is not 3PMSF severe-snow certified; it handles cold pavement and light slush but is not a substitute for a true winter tire on packed snow or ice. Low-profile UHP tires are sensitive to suspension camber alignment; verify alignment immediately upon installation and perform strict rotations every five thousand miles where fitments permit to avoid inner-shoulder wear.

Best-suited for: BMW 3 Series and M340i, Audi S4, Ford Mustang GT, Chevrolet Camaro SS, Tesla Model 3 Performance, Genesis G70, Porsche Macan, Honda Civic Type R.
