Do Rear Wheels Need Wheel Balancing?

[McCarlos]

Rear wheels do need wheel balancing. A wheel with unbalanced mass can cause severe vibrations during high-speed rotation. Although the vibrations from the front wheels are more noticeable to the driver, the vibrations from the rear wheels can also significantly impact driving safety. Therefore, even the rear wheels must undergo wheel balancing. A car's wheel is an assembly consisting of a tire and a rim. However, due to manufacturing imperfections, the mass distribution of this assembly may not be perfectly uniform. When the wheel rotates at high speeds, it can become dynamically unbalanced, leading to wheel vibrations and steering wheel shaking while driving. To prevent or correct this issue, wheel balancing is performed by adding counterweights to adjust the balance of the wheel's edges under dynamic conditions.
