After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. For the location of the tire and loading information label see Loading Your Vehicle on page 4-52. Make certain that all wheel nuts are properly tightened, see "Wheel Nut Torque" under Capacities and Specifications on page 5-108 for the proper wheel nut torque specification. {CAUTION: When rotating your tires, always use one of the correct rotation patterns shown here. If your vehicle has a compact spare tire or a spare tire that does not match your vehicle's road tires and wheels, in size and type, do not include the spare in the tire rotation. Rust or dirt on 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 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 or dirt off. See "Changing a Flat Tire" in the Index. 5-66
