Tire balancing is a mechanical adjustment that is required for an equal weight distribution of the tire and wheel around the axis. Even an imbalance of a few grams will produce centrifugal force as the wheel reaches highway speed. This force is not contained at the tire; rather, it is transmitted via the steering, suspension, and chassis components. Contemporary vehicles possess tight tolerances; that is, even the slightest imbalance will produce a measurable effect. These issues may occur slowly enough that they can be overlooked until the discomfort is undeniable.
