245/40ZR18 MICHELIN PILOT SPORT AS 4 97Y XL

The Michelin Pilot Sport AS 4 245/40ZR18 97Y XL is a breakthrough ultra-high-performance all-season tire engineered for sport sedans, performance coupes, and EV/hybrid vehicles that demand year-round capability without sacrificing summer-level grip. The Pilot Sport AS 4 bridges the gap between a dedicated UHP summer tire and a capable all-season, delivering exceptional dry and wet performance alongside confident cold-weather traction.

With a 97Y Extra Load (XL) rating and a ZR speed symbol indicating capability beyond 240 km/h, this tire is built for high-performance applications on 18-inch fitments. Michelin's Helio+ Technology compound remains pliable in colder temperatures for enhanced all-season grip, while the asymmetric tread pattern with large outer shoulder blocks delivers confident dry cornering and braking. The EV-C (Electric Vehicle Compatible) designation ensures optimized performance under the higher torque and weight demands of electric and hybrid vehicles. The 45,000-mile tread warranty and UTQG 540 AA A rating reflect outstanding treadwear longevity and maximum traction for a UHP all-season tire.
