BTS series rims and wheels are designed to answer the challenging need for heavy duty off-highway truck under tough operating conditions. Since the introduction of the Bead Taper Secure  (BTS) Series rims and wheels decades ago, customers worldwide in mining and industrial operations have experienced significant benefits. Some of the benefits are: vastly increased rim and component life, elimination of vibration along the axle, better air retention, less equipment downtime which leads to increased production, and up to 25% extended tire life. 

The innovative taper design of the BTS secures all rim components in place, eliminates any movement or flexing of the rim components (side rings, rim base, bead seat band, lock ring, and o-ring). The beads of the tire are secure and stable. Air loss and the problems associated with it are eliminated.  The taper design gives the side rings more surface area over which to seat. The increased contact area spreads the forces and pressures out evenly across the components. The thickness of this area gives the side ring the stability to react against the forces of the tire. The fully machined taper ensures an even distribution of the contact stresses.
