To keep tread in contact with the road, the wheel and the tyre have to be correctly balanced. Wheel imbalance can cause shaking or vibration through the steering wheel which may noticeably increase with speed. If wheel imbalance is left unchecked it can cause excessive mechanical wear and tread wear.
Wheel balancing is easily corrected using a computerised electronic wheel balancing machine to measure the imbalance. Once calculated, a small metal weight can be added to ensure the correct balance is achieved.
