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 "Part A: Scheduled Maintenance Services," in Section 6, for scheduled rotation intervals. When rotating your tires, always use the correct rotation pattern shown here. Rust or dirt on a -..lee., 3r on the parts to which it is fastened, can make wheel nuts become loose after atime. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where thewheel 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 brushlater, if you need to, to get all the rust or dirtoff. See "Changing a Flat Tire" in the Index. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certificationflire label. Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque" 5under Capacities and Specifications on page 104. 5-60
