Tyre balance is divided into dynamic balance and static balance.Dynamic imbalance will cause the wheel to swing, causing the wheel to produce wavy wear;Static imbalance will produce bump and jump phenomenon, often causing flat tire spot phenomenon.Periodically balance, therefore, not only can prolong the life of tires, it can improve the stability of the car to avoid driving at high speed with the tires swinging, beating, out of control and cause traffic accidents.The wheels of a car are made up of tires and wheels.However, due to manufacturing reasons, the mass distribution of this whole part cannot be very uniform.When the wheel of an automobile rotates at a high speed, it will be in a state of dynamic imbalance, causing the wheel to shake while driving and the steering wheel to vibrate.In order to avoid this phenomenon or eliminate the phenomenon that has already happened, it is necessary to make the wheel adjust the balance of each edge part by increasing the weight of the wheel under dynamic conditions.This process of correction is known as dynamic equilibrium.
