Why don't rear wheels need wheel balancing?

Rear wheels also need wheel balancing, as all four wheels of a car generally require balancing. If wheel balancing is not performed, abnormal vibrations may occur during high-speed driving, which can affect the vehicle's handling and high-speed stability, as well as potentially impact ride comfort. Wheel balancing doesn't need to be done regularly; it's only necessary after replacing new tires or repairing tires. During regular vehicle use, it's essential to maintain your car's tires periodically. Tires are the only components of a car that contact the road surface, directly affecting driving stability and safety factors.
I used to think that rear wheels didn't need balancing because they don't directly vibrate the steering wheel like the front wheels do. However, I later learned during a car repair that unbalanced rear wheels can also cause issues. I had a personal experience where, during a long highway drive, the entire car was shaking severely. After taking it to a repair shop, I found out it was due to unbalanced rear wheels. When tires rotate with uneven weight distribution, they can cause vibrations and noise, and over time, this can wear out the tire sidewalls and affect the suspension system. In fact, all wheels require regular balancing, especially after getting new tires or a tire repair. This helps extend tire life and improves driving comfort. Now, I always make sure to have the technician check all four wheels during every maintenance service to avoid unnecessary repair costs.
From a safety perspective, neglecting rear wheel balancing is definitely not a trivial matter. I understand many people only pay attention to it when front wheel vibrations are noticeable, but rear wheel imbalance, though not immediately felt, poses greater hidden dangers. For instance, during sharp turns or overtaking, rear wheel wobble can disrupt vehicle balance, increasing the risk of losing control; at high speeds, such vibrations can transmit to the car body, leading to driver fatigue or accidents. I strongly advise against ignoring it, as uneven tire wear can also shorten braking distances, threatening road safety. Regular wheel balancing can prevent these issues—it's a small investment with high returns.
When it comes to cost and practicality, neglecting rear wheel dynamic balancing is actually a waste of money. I've done the math: if a car ignores rear wheel balancing for a few months, tire wear may accelerate by 30%, leading to premature replacement of tires, which costs hundreds of dollars and isn't worth it. Dynamic balancing is not expensive; just a few dozen yuan per session can ensure your tires endure tens of thousands of kilometers with even force distribution. I maintain a cost-saving habit by performing full-wheel balancing every 5,000 kilometers or when changing tires, avoiding additional repair expenses, making driving smoother and more economical.
