1.Under what circumstances need to do dynamic balancing?

Once the tires are assembled with the rim, a set of dynamic balance adjustments is required.

2.In  what case, you can no longer continue to use the weights?

In the process of trimming, the weight can not be endlessly attached, it should be based on the principle of attaching the weight as little as possible, because if the weight is too much, not only will the tire dynamic balance be corrected, but instead As the weight of the wheel increases due to excessive weights, the moment of inertia of the wheel increases, which may increase the degree of wheel shake. Under normal circumstances, the lead on the inner side of the rim has not been balanced after using 70 grams of weight, then consider using other methods.

3.The effect of the wheel imbalance.

Steering wheel will have regular jitter, The faster the speed, the more obvious, and there will be a sense of resonance in the car when it is serious.

The wheel continues to run in an unbalanced state, and the long time will cause the tire to be eccentric.

If the wheel imbalance is serious, it will be in such a form for a long time, causing damage to the bearing and the suspension, affecting the life of the mechanical structure.
