Wheel alignment

Wheel alignment, sometimes referred to as wheel tracking, is a vehicle maintenance procedure involving adjustment of the geometric angles of a vehicle’s wheels. Proper alignment helps prevent abnormal tire wear and assists in maintaining stable vehicle handling and straight-line travel without pulling to one side.
