Why Balancing Is Important
When a wheel is unbalanced, there is an unequal distribution of weight around the rim of the wheel and tire assembly. When one area is heavier or lighter than the rest, this can cause uneven treadwear, vibration, and increase the stress on the front end parts and may cause them to wear prematurely.
When to Balance
You should have your wheels balanced whenever a tire is replaced, when a balance weight is moved or removed, and whenever you purchase new tires. Of course, at the first sign of vibration or irregular treadwear, your car should be thoroughly checked for wheel balance and alignment.
How We Balance a Wheel
To balance a wheel we use a computer balancing machine to determine where the heavy spots are. Weights are then attached to the exterior or interior of the wheel to counteract centrifugal forces acting on the heavy areas when the wheel is turning.
