Should Wheel Balancing Be Done on Two or Four Wheels?

Wheel balancing only needs to be performed on two wheels. The reason for performing wheel balancing is that a wheel is an assembly composed of a tire and a rim. Due to manufacturing variations, the mass distribution around the wheel is not perfectly uniform. When a vehicle is driven at high speeds, the wheels rotate rapidly, and any mass imbalance can cause vibrations, steering wheel shaking, and other issues. To address this, balancing weights are added to achieve equilibrium around the wheel's circumference. Wheel balancing is necessary in the following situations: 1. When the steering wheel shakes or the wheels produce rhythmic abnormal noises during high-speed driving; 2. After replacing tires, rims, or repairing tires; 3. When the wheels have suffered significant impacts or balancing weights have been lost due to rough road conditions.

I had the same issue during my last tire maintenance. At first, I thought only balancing the two front wheels would suffice, since they control steering and should be prioritized. But after driving for a while, the car vibrated violently on the highway, even shaking the steering wheel. The mechanic explained that rear wheel imbalance can also transfer to the front, causing overall instability. Now, I always insist on balancing all four wheels during tire changes or routine maintenance. This not only extends tire life and reduces uneven wear but also improves fuel efficiency and driving smoothness. Pro tip: It's usually checked during wheel alignment—low cost but high impact.

In daily car repairs, I often encounter customers asking this question, and my simple advice is to do all four wheels without fail. If only the front two wheels are balanced while the rear wheels remain unbalanced, the imbalanced force can transfer to the car body, causing more severe vibrations and even abnormal tire wear. Over time, this can also damage the suspension system. That's why I always recommend a comprehensive check and balancing all four wheels simultaneously. Cost-wise, it averages a few dozen bucks per wheel, and doing it all at once saves time and hassle while improving driving comfort. Making it a habit ensures your car runs longer and safer.

From personal experience, balancing all four wheels is far better than just two. I once tried balancing only the front wheels, but found the car vibrated excessively on bumpy roads, affecting handling and increasing risks at higher speeds. Balancing all four eliminates the shaking, ensures even tire wear, and reduces the need for frequent replacements. Don’t overlook this during maintenance—it’s a quick step to ensure stability.
