1. The tires should be rotated at the specified intervals and whenever uneven wear is noticed. Since the vehicle will be raised and the tires removed anyway, check the brakes (see Brake system check) at this time.
2. Radial tires must be rotated in a specific pattern (see illustrations). Most models are equipped with non-directional tires, but some models may have directional tires, which have a different rotation pattern. When rotating tires, examine the sidewalls. Directional tires have arrows on the sidewall that indicate the direction they must turn. The left and right-side tires must not be rotated to the other side.

3. Refer to the information in Jacking and towing at the front of this manual for the proper procedures to follow when raising the vehicle and changing a tire. If the brakes are to be checked, do not apply the parking brake as stated. Make sure the tires are blocked to prevent the vehicle from rolling.
4. Preferably, the entire vehicle should be raised at the same time. This can be done on a hoist or by jacking up each corner and then lowering the vehicle onto jack stands placed under the frame rails. Always use four jack stands and make sure the vehicle is firmly supported.
5. After rotation, check and adjust the tire pressures as necessary and be sure to check the lug nut tightness. Ideally, lug nuts should be tightened to the torque listed in this Chapter’s Specifications with a torque wrench, and rechecked after 25 miles of driving.
