Service and Appearance Care Wheel Alignment and Tire Balance The wheels on yourvehicle 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 needto have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or 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. Wheel Replacement Replace any wheel thatis bent, cracked or badly rusted. If wheel nuts keepcoming loose, the wheel, wheel bolts, and wheel nuts should bereplaced. If the wheel leaks air out, replace it (except some aluminum wheels, which can sometimes be repaired). See your Pontiac dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. [f you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them mly with new GM original equipment sarts. This way, you will besure to have :he right wheel, wheel bolts, and wheel nuts for your Pontiac model. 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.
