Properly balanced tires are important for driving comfort and long tire life. Unbalanced tires can cause vibration, resulting in driver fatigue, premature tire wear and unnecessary wear to your vehicle’s suspension.

Your tires are the only thing keeping your car on the road and driving safely. A tire’s footprint, or the area that is actually in contact with the road, is quite small. This tiny tire footprint is what creates the traction that allows your car to accelerate, decelerate, and turn. If these contact points are hampered by poor tread or under inflation, your ability to steer, start, and stop can be adversely affected.

 

Tire Rotation

Tire rotation is the practice of swapping the front tires of a car with the back tires at regular intervals. The basic idea of tire rotation is to extend the life of the tires by allowing more even tread wear.
