A wheel alignment is the adjustment of the angles of the wheels so that they are set to the specifications of the vehicle manufacturer. The main reasons for performing a wheel alignment is to maximise the tyre life and ensure the vehicle drives in a true/straight line.

A wheel alignment should be performed when new tyres are fitted and then again on a fairly regular basis, once or twice per year. The frequency of wheel alignments depends on the distance travelled along with the conditions of the roads on which it has been driven.
