After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. See Loading Your Vehicle on page 250 for an example of the tire and loading information label and its location on your vehicle. Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque" under Capacities and Specifications on page 384. {CAUTION: Directional Tires If your vehicle has 215/45ZR17 size tires, they are directional tires and must roll in a certain direction for the best overall performance. The direction is shown by an arrow on the tire sidewall. Because these tires are directional, they should be rotated as shown here. These tires should only be moved from front to rear and rear to front on the same side of the vehicle. Do not include the compact spare tire in your tire rotation. Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel bolts 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.
