275/45R21 Michelin CrossClimate2 All Weather
Category: All Season – Grand Touring
The Michelin CrossClimate 2 is a grand touring all-season tire designed for exceptional tread life and traction when worn. The V-style directional tread design is engineered to deliver excellent water and slush displacement. The tread pattern also uses geometry and timing variation to help reduce road noise and discomfort. The CrossClimate 2 braking traction is enhanced by chamfers that increase contact with the road surface under load while the groove-less pattern evens out those forces to benefit wear characteristics. It also has a 100,000km tread life warranty for all sizes.Read Reviews
