See "When It's Time for New Tires" and"Wheel Replacement" later in this section for more information. When rotating your tires, always use the correctrotation pattern shown here. Don't include the compact spare in your tire tire rotation. After thetires have been rotated, adjust the fi-ont and rear inflation pressures as shown on the Tire-Loading Information label. Makecertain that all wheel nuts are properly tightened. See "WheelNut Torque" in the Index. The purposeor 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 Index for scheduled rotation intervals. Rust or dirt a wheel, or on the parts to which on it is fastened, can make wheel nuts become loose after atime. The wheel could comeoff and cause an accident.
