Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance.
Adjustments to wheel alignment and tire balancing will not be necessary on a regular basis.
However, if you notice unusual tire wear or your vehicle pulling to one side or the other, the alignment may need to be checked. If you notice your vehicle vibrating when driving on a smooth road, your tires and wheels may need to be rebalanced. See your dealer for proper diagnosis.
