Dynamic balance refers to the asymmetric weight distribution produced by the force of the tire when it rotates, usually at a higher speed._x000D_ In the tire factory, a balancing machine installed on the tires and wheels tests the wheels. The assembly is accelerated to 300 RPM or higher, and the force imbalance is measured with the tire rotation sensor._x000D_ For the hook-type balance weight, the unreasonable fit clearance is also the reason for its loss during driving. PackageList: 1 x Pack of Tire Wheel Balancing Weights (50pcs, 20g/pc) Note: Professional installation is strongly recommended. Please install with professional tools.
