Special Notes About Wheels and Tires

  1. 1
    Do not use wheels or tires other than the specific types.
  2. 2
    Aluminum wheels are easily scratched. When washing them, use a soft cloth, never a wire brush. If the vehicle is steam cleaned, do not allow boiling water to contact the wheels.
  3. 3
    If alkaline compounds (such as saltwater or road salts) get on aluminum wheels, wash them as soon as possible to prevent damage. Use only a neutral detergent.

NOTES REGARDING TIRE REPLACEMENT

Note the following points when tires are to be removed from or mounted onto the wheels.

Tire Replacement Notes

  1. 1
    Be careful not to damage the tire bead, the rim bead, or the edge of the rim.
  2. 2
    Apply a soapy solution to the tire bead and the edge of the rim.
  3. 3
    Use a wire brush, sandpaper, or cloth to clean and remove all rust and dirt from the rim edge and the rim bead. For aluminum wheels, use only a cloth for this purpose; never use a wire brush or sandpaper.
  4. 4
    Remove pebbles, glass, nails, and other foreign items embedded in the tire tread.
  5. 5
    Be sure the air valve is installed correctly.
  6. 6
    After mounting a tire on a wheel, inflate it to 250—300 kPa (2.55—3.06 kgf/cm², 35.55—42.66 psi). Verify that the bead is seated correctly onto the rim and that there are no air leaks. Then reduce the pressure to the specified level.
  7. 7
    If a tire iron is used to change a tire on an aluminum wheel, be sure to use a piece of rubber between the iron lever and the wheel to avoid damage to the wheel. Work should be done on a rubber mat, not on a hard or rough surface.

INSPECTION / ADJUSTMENT

Check the following and adjust or replace as necessary.

Inspection / Adjustment

  1. 1
    Air pressure. Check the air pressure of all tires, including the spare tire, with an air pressure gauge.
    The air pressure must be measured when the tire is cold.

  2. 2
    Wheel runout. Set the probe of a dial indicator against the wheel, and turn the wheel one full revolution.
