Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 to I3 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See "When It's Time for New Tires" and "Wheel Replacement" later in this section for more information. The purpose of regular rotation is to achieve more lrniform wear for all tires on the vehicle. The first rotation is the most important. See "Scheduled Maintenance Services" in the Index for scheduled rotation intervals. When rotating your tires, always use the correct rotation pattern shown here. If your vehicle has a compact spare tire, don't include it in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the CertificatiodTire label. Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque'' in the Index. Rust or dirton a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In anemergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper orwire brush later, if you need to, to get all the rust or dirt off. (See "Changing a Flat Tire" in the Index.)
