CENTRABALANCE is a self adjusting wheel balancing which offers you guaranteed performance and savings. It works by centrifugal force which precisely positions the liquid in counterweight positions. This will eliminate the problem of tire cupping, reduces vibration resonance making for a smoother ride. Centrabalance also works with gravity to create a down force effect that holds the tire down on the road. This gives the tire more footprint and better control in cold, icy and wet conditions.
