The ProMotion Viper is a LP carcass based tire specifically designed for today's carpet and turf racing facilities. The LP design provides more stability through less sidewall deflection. The mini pin design features "tapered" pins that progressively get larger closer to the tire carcass, as well as a directional radius design. The Viper also features dual mini outside "wedges" with a single small radial rib. This combination has showed to be extremely versatile and provide both the grip and slip to conquer most carpet and turf surfaces with just one tread pattern.
