Wheel Alignment
Vehicle suspensions can wear with age and repeated heavy use. Rough road surfaces and an occasional pothole can change the vehicle's wheel alignment.
A wheel alignment can improve your steering control and overall vehicle handling (Maximize predictable handling and driver control).
Wheel alignment refers to the proper setting of the axle geometry as well as tracking of all axles on a vehicle. This important step will keep your vehicle driving the way it was designed to.
It can also help prevent abnormal tyre wear by bringing the vehicle suspension components back to the vehicle manufacturer's specifications and increases overall safety of vehicle operation.
For safe and smooth rides Have your alignment checked periodically as specified by vehicle manufacturer manual or whenever there is an indication of trouble such as uneven wear in tyres, pulling, vibrations etc.
Major wheel alignment elements that affect tyre life:
Toe Settings: First and foremost element
Rear Axle Alignment Geometry: 2nd element
Camber: 3rd element
