Wheels that are not balanced or are out of balance generally produce a vibration that is uncomfortable to drive in and results in premature wearing of suspension and steering components, rotating parts and tyres. Correctly balanced wheels help to eliminate vibration and avoid premature wear caused by an imbalance in the rotating wheel and tyre assembly. The first sign that your wheels may be out of balance is when your steering wheel starts to wobble above a certain speed. The light weight of modern cars means that they don't dampen down the vibrations caused by spinning wheels in the way that older, heavier vehicles could.
A driver may not always sense an imbalance at the steering wheel. It could be present with but dampened by the vehicle weight. This is why balancing is equally important for both front and rear wheels. Wheels are balanced on a wheel balancing machine. The machine rotates the tyre and wheel assembly and automatically calculates the weight and location of the balance counter weight. As a result of wheel balancing, you should notice a smoother ride and better wear from your tyres, again saving you time and money.
