The Ken-Tool Balancing Beads for Trucks are designed to balance not only the tire and wheel, but the complete axle end and all the moving components of the wheel assembly. The Balancing Beads are tiny glass beads with a proprietary coating that repels moisture, prevents clumping and features a unique memory technology to stabilize the beads inside of the tire. The beads use the rotating tire's centrifugal force to distribute beads to the critical point opposite the imbalance, and respond to changes in speed and direction to maintain rotating balance. The beads are available in 1 oz. to 16 oz. drop-in plastic bags, with the number of bags used per tire determined by tire size. They can be sold in individual bags, or in case lots.
