How Many Wheels Need Dynamic Balancing?
2 Answers
Dynamic balancing should be performed on all four tires. Additional information about dynamic balancing is as follows: 1. Dynamic balancing refers to the process of determining the position of the unbalanced weight of a rotor and the location and size of the balancing weight that needs to be added, which can only be measured when the rotor is in a rotating state. 2. Dynamic balancing can not only eliminate the dynamic unbalanced couple but also the centrifugal force caused by static imbalance. 3. Automotive dynamic balancing refers to the balance between the wheels when the vehicle is in motion. 4. To prevent an unbalanced state caused by uneven mass distribution in various parts of the vehicle during driving, dynamic balancing is necessary for the car.
From my years of experience in auto repair, I strongly recommend doing wheel balancing on all four tires. Each tire can become unbalanced due to manufacturing variations, wear, or improper installation, and balancing just one or two often doesn't solve the problem. For example, I once worked on a car where the customer only balanced the front wheels, but the rear wheels still vibrated severely at high speeds, causing the steering wheel to shake. It wasn't until all wheels were balanced that the car ran smoothly. The process is quick, usually taking about ten minutes per wheel—just machine testing and adding counterweights to adjust. Don't try to save money by balancing only some wheels; it not only makes driving uncomfortable but also accelerates tire wear and can even affect braking performance. Safety first—it's best to check all wheels after changing tires or whenever you feel vibrations.
