Metzeler replaces the Roadtec Z8 Interact with the new Roadtec 01. Sporting an all-new tread pattern, profile and rubber compounds the Roadtec 01 promises to be an exceptional rain tire. Grip on the sides of the rear tire is enhanced with silica-infused shoulder compounds and a center segment with a new mix of silica and carbon black for longer straight-line life. The front tire benefits from a uniform silica-based design suitable for a wide range of conditions. Get a closer look at the Metzeler Roadtec 01 tires in the product spotlight video below.
