Maintenance Wheel alignment and tire balance 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 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. Tread wear indicator WARNING - Replacing tires To reduce the chance or serious or fatal injuries from an accident caused by tire failure or loss of vehicle control: • Replace tires that are worn, show uneven wear, or are damaged. Worn tires can cause loss of braking effectiveness, steering control, and traction. • Do not drive your vehicle with too little or too much pressure in your tires. This can lead to uneven wear and tire failure. • When replacing tires, never mix radial and bias-ply tires on the same car. You must replace all tires (including the spare) if moving from radial to bias-ply tires. (Continued) 1LDA5026 CAUTION Improper wheel weights can damage your vehicle's aluminum wheels. Use only approved wheel weights. Tire replacement If the tire is worn evenly, a tread wear indicator will appear as a solid band across the tread. This shows there is less than 1/16 inch (1.6 mm) of tread left on the tire. Replace the tire when this happens. Do not wait for the band to appear across the entire tread before replacing the tire. 7 36
