The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See "Scheduled Maintenance Services" in the Maintenance Schedule booklet for scheduled rotation intervals. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque" in the Index. I A CAUTION: Rust or dirton a wheel, or on the partsto which it is fastened, can make wheel nuts become loose after a time. The wheel could comeoff and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust ordirt off. (See "Changing a Flat Tire" in the Index.) When rotating your tires, always use the correct rotation pattern shown here. Don't include the compact spare tire in your tire rotation. 6-41
