Maintain tires in proper balance

Out-of-balance tires can not only cause uneven tread wear and an uncomfortable ride but also excessive wear on the suspension and other components. An out-of-balance tire can be detected by a severe thumping, usually most pronounced at highway speeds.
If such a condition occurs, have your tires dynamically balanced as soon as possible. An experienced technician can usually determine which tire is out-of-balance by driving the car.
Tire balancing involves placing weights in appropriate places on the bead or inner circumference of the wheel. Tires should always be balanced when first installed, and whenever they are remounted.
