Do Rear Wheels Need Dynamic Balancing?

[LaElisa]

Rear wheels of a car do require dynamic balancing. Situations that necessitate dynamic balancing include: 1. After replacing new tires or post-collision repair; 2. Unilateral wear on front or rear tires; 3. Excessive heaviness or shaking of the steering wheel while driving; 4. The car veering to the left or right when moving straight. Dynamic balancing is a process where weights are added to the wheel in motion to correct the balance of each edge part, aiming to maintain the wheel's balance during rotation. A car's wheel is an assembly of the tire and rim. However, due to manufacturing variations, the mass distribution across the assembly may not be perfectly uniform. When the wheel rotates at high speeds, this can lead to dynamic imbalance, causing the wheel to shake and the steering wheel to vibrate during driving.

I've been repairing cars for over a decade, and many people overlook rear wheel balancing. Actually, whether it's front or rear wheels, any rotating tire needs balancing. Especially when driving at high speeds, if the steering wheel doesn't shake but the whole car feels floaty, it's likely due to unbalanced rear wheels. Last month, a BMW 3 Series owner came to the shop—he had new tires installed but didn't balance the rear wheels. When he drove at 110 km/h, the back seats vibrated like a massage chair. Balancing is actually super simple—just attach lead weights to the inner side of the rim. If you frequently drive long distances or just changed tires, I highly recommend balancing all four wheels. It costs just around a hundred bucks but gives you a rock-solid driving experience.

When it comes to wheel balancing, my 20 years of driving experience tells me all four wheels need it. Last week when I took my daughter's Golf out, the whole rear end shook at speeds above 60 km/h. The repair shop found the rear wheel was off by 60 grams. The mechanic said modern sedans all have independent suspension, so unbalanced rear wheels still affect stability. Especially when going over speed bumps - you really feel the jolt when an unbalanced wheel hits the ground. My advice: always get balancing after tire changes, and during routine maintenance ask the technician to spin the wheels on the machine to check the data. After all, when it comes to safety, even minor issues deserve attention.

Rear wheel dynamic balancing is absolutely necessary, my friend! Just the other day, my motorcycle's rear wheel wasn't balanced, and at 80 km/h the handlebars were shaking like crazy. The same principle applies to cars - wheels spin thousands of times per minute, and even a few grams of imbalance can make the entire suspension system struggle. This is especially true for rear-wheel drive vehicles where power is directly transmitted through the rear wheels - imbalance causes much more noticeable body vibration. I recommend checking it every 20,000 km or after tire repairs. The balancing machine at repair shops can detect imbalance in just half a minute of rotation - if it's off, just have the mechanic adjust it with lead weights. Safety is no small matter, don't try to save those few dozen dollars.
