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