SPECIAL NOTES ABOUT WHEELS AND TIRES
1. Do not use wheels or tires other than the specified types.
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. 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.
9MUOQX-004
NOTES REGARDING TIRE REPLACEMENT
Note the following points when tires are to be removed from or mounted onto the wheels.
1. Be careful not to damage the tire bead, the rim bead, or the edge of the rim.
2. Use a wire brush, sandpaper, or cloth to clean and remove all rust and dirt from the rim edge and the
rim bead.
3. When cleaning aluminum wheels, use a soft cloth, never a wire brush or sandpaper.
4. Remove any pebbles, glass, nails, and other foreign items embedded in the tire tread.
5. Be sure the air valve is installed correctly.
6. Apply a soapy solution to the tire bead and the edge of the rim.
7. After mounting a tire onto a wheel, inflate the tire to 250-300 kPa (2.55-3.06 kg/cm2, 35.55-42.66
psi). Check to be sure that the bead is seated correctly onto the rim and that there are no air leaks. Then
reduce the pressure to the specified level.
8. 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.

Tire Wear
1. Check the remaining tread.
Remaining tread
Standard tires: 1.6mm (0.063 in) min.
Snow tires: 50% of tread ’ _,I’
2. The tire should be replaced if the wear indicators are
exposed.
Inspection (Tire and Wheel)
The wheel or tire should be replaced if any crack, damage,
deformation or other problem is found.
Wheel and Tire Runout
1. Jack up the vehicle and place it on safety stands.
2. Set the probe of a dial indicator against the wheel, and meas-
ure the runout through one full revolution.
Runout:
_..’
Horizontal Aluminum wheel: 2.0 (0.079), Steel wheel: 2.5 (0.098)
Vertical 1.5 (0.059)
3. Replace the wheel if necessary.
Caution
l Adjust wheel balance after replacement of a wheel
or tire.
Lug Nut
1. Verify that the lug nuts are tightened to the specified torque.
Tightening torque:
