When a wheel rotates, asymmetries of mass may cause it to hop or wobble, which can cause ride disturbances. It can also result in a wobbling of the steering wheel or of the entire vehicle. The ride disturbance usually increases with speed. Vehicle suspension can become excited by unbalancing forces when the speed of the wheel reaches a point that its rotating frequency equals the suspension’s resonant frequency.
Tyres are balanced by two methods: static balancers and dynamic balancers. When tyres are fitted to wheels they are measured on a balancing machine and correction weights are applied to counteract the combined effect of the tyre and wheel unbalance. After sale, tyres are rebalanced if driver vibrations return.
