Do Rear Wheels Need Dynamic Balancing?
2 Answers
Rear wheels do need dynamic balancing, as the effectiveness of tire dynamic balancing directly affects the stability of the vehicle while driving. A car's wheel is an integral unit composed of the tire and the rim. However, due to manufacturing reasons, the mass distribution of this unit cannot be perfectly uniform. When the car's wheels rotate at high speeds, this can lead to an unbalanced state, causing the wheels to shake and the steering wheel to vibrate during driving. To prevent this phenomenon or to eliminate it if it has already occurred, it is necessary to correct the balance of the wheel's edges by adding counterweights while the wheel is in motion. This correction process is commonly referred to as dynamic balancing.
The rear wheels also need wheel balancing, which is quite important for driving safety. I used to think the rear wheels were just supporting roles, not responsible for steering, so I didn't pay much attention to them. But once on the highway, the rear of the car shook violently, making it very uncomfortable. Upon inspection, it turned out the rear wheels were unbalanced. Body vibrations can worsen handling, especially during sharp turns, and accelerate tire wear. If not addressed promptly, it can even lead to problems with the suspension system and bearings, costing more to repair. Now, during every maintenance session, I insist on balancing both front and rear wheels—it's simple and affordable. The balancing operation only costs a few dozen yuan and can be done quickly on the shop's equipment to ensure even wheel rotation. After adopting this habit, the car drives more steadily, and my family says the back seat feels much more comfortable. In short, don't skip rear wheel balancing—it greatly contributes to overall driving safety and comfort.
