Should Wheel Balancing Be Done on Two or Four Wheels?

[VonHeidi]

Wheel balancing only needs to be performed on two wheels. The reason for performing wheel balancing is that a wheel is an assembly composed of a tire and a rim. Due to manufacturing variations, the mass distribution around the wheel is not perfectly uniform. When a vehicle is driven at high speeds, the wheels rotate rapidly, and any mass imbalance can cause vibrations, steering wheel shaking, and other issues. To address this, balancing weights are added to achieve equilibrium around the wheel's circumference. Wheel balancing is necessary in the following situations: 1. When the steering wheel shakes or the wheels produce rhythmic abnormal noises during high-speed driving; 2. After replacing tires, rims, or repairing tires; 3. When the wheels have suffered significant impacts or balancing weights have been lost due to rough road conditions.
