Is Rear Wheel Dynamic Balancing Necessary?
3 Answers
Rear wheel dynamic balancing is necessary when the car has new tires installed or after collision repairs. Dynamic balancing is a process that corrects the balance of the wheel edges by adding counterweights while the wheel is in motion, ensuring the wheel remains balanced during rotation. The steps for dynamic balancing are: 1. Remove the original counterweights before performing dynamic balancing; 2. Use a specialized dynamic balancing machine to measure the weight distribution of the wheel; 3. Add counterweights of appropriate weight at the corresponding positions. Situations that require dynamic balancing include: 1. After installing new tires or collision repairs; 2. Uneven wear on one side of the front or rear tires; 3. Heavy or shaking steering wheel while driving; 4. The car pulling to the left or right when driving straight.
I've been driving for over a decade, and rear wheel dynamic balancing is absolutely not something to overlook. Last time on the highway, when the speed exceeded 80km/h, the back of the car shook so badly that even my wife felt uncomfortable. Took it to the repair shop and found out it was a rear wheel balance issue. They added balancing weights to adjust the weight distribution, and the shaking stopped immediately. Dynamic balancing ensures the tires rotate evenly, preventing vibrations and unnecessary noise, especially since the rear wheels bear more load, like when carrying heavy loads or in rear-wheel-drive vehicles. Not balancing them can accelerate wear on one side of the tire, shortening its lifespan and costing extra money for premature replacements. I recommend checking it every 10,000 to 20,000 kilometers or doing it when replacing new tires—it only costs a few dozen bucks each time.

As a new driver who just got my license, I initially didn't understand why wheel balancing was needed for rear wheels. Later I realized that although rear wheel imbalance doesn't directly affect steering wheel feedback like front wheels, it causes more severe whole-body vibrations. For example, when driving on highways, excessive seat vibration in the rear or increased trunk noise often indicates rear wheel issues. Wheel balancing essentially equalizes weight distribution to prevent uneven tire wear and handling risks. I've come to realize that neglecting rear wheels may lead to reduced traction over time, making the car more prone to skidding in rain or snow. So I suggest paying equal attention to both front and rear wheels.
