Michelin Pilot Sport All Season 4 265/40ZR18XL 101Y Performance Tire
Michelin Pilot Sport All Season 4 265/40ZR18XL 101Y is an ultra-high-performance (UHP) tire designed to provide supercar-level grip and precision handling in all weather conditions. Chosen as the first all-season tire for the mid-engine Chevrolet Corvette, it features Extreme Silica+ and Helio+ compounds to maintain maximum traction on dry, wet, or snow-covered roads. With an Extra Load (XL) rating and Y-speed capability (up to 186 mph), this tire bridges the gap between track-ready summer tires and dependable year-round rubber. Backed by a 45,000-mile limited warranty, it offers significantly more tread life than leading competitors without sacrificing steering reactivity.
