Once a vehicle's tires do not wear at the same rate, a tire rotation will help prolong the life of a tire. A tire rotation consists of removing the wheels and moving the front tires to the rear and the rear tires to the front.
There are several reasons why a tire rotation should be performed. The most common reason is that front tires wear differently than the back tire. By rotating the tires, it will even out the wear and make the tires last longer. Also, when the tires are rotated, technicians check the tires for proper inflation and for any damage that can affect the safety of your vehicle. Damage or deterioration to the inside tread wall might never be seen unless the tire is rotated.
Most manufacturers have recommendations on when a tire rotation should be performed. While most manufacturer factory warranties and extended auto warranties do not cover the cost of a tire rotation, there are maintenance plans available that will cover the cost.
