Michelin Defender All-Season Radial Tire - 185/65R15 88T MaxTouch Construction combined with the interlocking action of Michelin's Breakthrough IntelliSipe technology delivers impressively long wear life by providing exceptional tread block rigidity while optimizing the tire's contact with the road during acceleration, braking and cornering. Exceptional grip provided by IntelliSipe Technology maximizes the number of sipes within the tire, which allows you to brake confidently when you need to most for greater peace of mind in stressful driving situations. The interlocking action of IntelliSipes creates a more rigid tread block, which allows for a reduced starting tread depth leading to lower rolling resistance so you can save fuel without sacrificing safety or longevity.
