If you start to feel any vibration should start investigating as it will cause premature tyre wear, decrease the service life of steering components, ruin wheel bearings & cause poor handling and the first initial item to check should always be wheel balancing.
Wheels that are not balanced or are out of balance generally produce vibrations that make the vehicle uncomfortable to drive.
Correctly balanced wheels help to eliminate vibration and avoid premature wear caused by an imbalance in the rotating wheel and tyre assembly.
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.
However, 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.
