Michelin 38869 Pilot Sport AS 4 245/30ZR20 90Y XL All-Season Ultra High Performance Tire

The Michelin Pilot Sport AS 4 is an ultra-high performance all-season tire designed for drivers of high-end sports cars, sporty coupes, performance sedans, crossovers, and SUVs who demand exceptional year-round performance. This tire delivers outstanding grip in dry, wet, and light snow conditions without compromising on tread life or ride comfort.

Advanced Performance Technologies:

• Dynamic Response Technology: Track-proven innovation that evenly distributes forces and temperatures across the contact patch during hard cornering, improving handling precision and extending tread wear
• Extreme Silica+ Compound: Race-inspired tread compound engineered with maximum silica levels to deliver superior grip on wet and slick pavement
• 360-Degree Variable Sipe Technology: Full-depth interlocking sipes create biting edges that enhance traction in wet conditions and light snow
• Helio+ Technology: Advanced rubber compound maintains flexibility and grip even in freezing temperatures
• Asymmetric Tread Pattern: Reinforced outboard shoulder blocks with increased rubber contact deliver exceptional lateral grip and cornering stability
• Wide Circumferential Channels: Large rain grooves rapidly evacuate water from the contact patch to resist hydroplaning and maintain wet traction

Performance Benefits: Up to 29% longer tread life compared to leading competitors, 45,000-mile limited treadwear warranty, UTQG rating of 540AA, and Y-speed rated for speeds up to 186 mph. The Extra Load (XL) construction provides enhanced load-carrying capacity for high-performance vehicles. Black sidewall (BSW) styling complements modern wheel designs.

This tire was the first all-season tire chosen by Chevrolet for the Corvette and is Original Equipment on numerous high-performance vehicles, demonstrating Michelin's engineering excellence and manufacturer confidence in all-season performance capabilities.
