Dynamic balance ensures that the wheels will not swing left and right when rotating at a high speed. Add or reduce this block when adjusting to the appropriate value according to the relevant data to achieve the purpose of balance. When the vehicle is driving at a high speed, the steering wheel is constantly shaking, which is a problem with dynamic balance. Dynamic imbalance will cause the wheels to sway and cause the tires to produce wave-shaped wear; static imbalance will produce bumps and bounce, and often cause flat spots on the tires. Therefore, regular detection of balance can not only prolong the life of the tires, but also improve the stability of the car when driving, and avoid traffic accidents caused by tire swings, bounces, and loss of control during high-speed driving.
