Tested: Metzeler Sportec M5 Interact

With its clever Interact technology Metzeler has created a tyre that has a varying carcass construction to alter how the rubber performs. Without going too deeply the M5 consists of five bands of belting that vary in stiffness. At the outer edges of the tyre the carcass is quite flexible, allowing the rubber to move around and generate more heat and therefore grip, while nearer the tyre’s centre the carcass is stiffer, reducing the rubber’s movement and decreasing its wear.
