Wheel alignment
Wheel alignment is part of standard automobile maintenance that consists of adjusting the angles of the wheels so that they are set to the car maker’s specification. The purpose of these adjustments is to reduce tire wear, and to ensure that vehicle-travel is straight and true (without “pulling” to one side). Alignment angles can also be altered beyond the maker’s specifications to obtain a specific handling characteristic. Motorsport and off-road applications may call for angles to be adjusted well beyond ‘normal’ for a variety of reasons.
