See your Chevrolet dealer if any of these conditions exist. Wheel Alignment and Balance Your dealer will know the kindof wheel Tire you need. Each new wheel should have the same load carrying capacity, diameter, width, offset, and be mounted thesame way as the one it replaces. If you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheelbolts, and wheel nuts for your Chevrolet model. The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one wayor the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. NOTICE: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer/odometer calibration, headlight aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis.
