The unique design of the Taper Secure Radial (TSR) Series uses a taper concept to secure all components in place. Absolute stability of components and the tire is achieved as movement between parts is eliminated. When the tire is inflated, the rim parts lock into their tapered landing areas.

The key benefit of the TSR design is absolute tire support. The flanges of the wheel do not move on the base. The tire is anchored with complete stability and no air pressure is lost. As well as extending tire life, the life of rim components is increased as there is no wearing or fatiguing of the parts from component movement.
