Suprema Spina use the same world leading technology as some of the best WSBK and MotoGP teams. The PTFE based heating elements maintain a constant temperature of 85°C / 185°F with the additional benefit of lateral heating elements on the sidewall. These elements enable heat to travel to the rim which helps maintain tire temperature even after the warmers have been removed. Each tire warmer contains 40 meters of heating wires that are in a radial arrangement for quicker heat up and uniform temperature.
