Counteract Balancing Beads are a unique and proven method for balancing tires and wheels on heavy duty trucks, trailers, and buses, and are the ideal replacement for the toxic lead weights that are currently being phased out. These are tiny synthetic beads that balance the wheel/tire by equalizing the weight inside the tire as the wheel assembly rotates. Counteract Balancing Beads balance tires for their complete lifetime by readjusting as required and doing so economically.
