Michelin's Pro3 Optimum provides the features you need in a distance and touring tire. The front and rear-specific design brings out the best in each tire for impressive function. The front tire utilizes a super-grippy compound for added traction and improved braking performance. While the rear is made from a harder compound for durability and longer life. Plus, the Optimum includes a puncture-resistant layer within the tread for increased durability.
