1. WHEELS
The vehicle is equipped with hub-mounted
wheels as standard equipment, all studs and
nuts have right-hand threads When the vehicle
is provided with stud-mounted wheels, wheel
studs and nuts on the left side of the vehicle
have left-hand threads whereas those on the
right side have right-hand threads.. Either steel
wheels or optional aluminum-polished wheels
may be installed on the vehicle. Both are
mounted with radial tubeless tires.
All wheel dimensions are 22.50 X 9.0 inches
(571.5 X 228.6 mm) for 315/80 R 22.5 tires
except inner drive wheels ,which are always steel
wheels and 22.50 X 8.25 inches (571.5 X 209.6
mm) for 315/80 R 22.5 tires. All other wheels can
either be steel or aluminum wheels.

2. WHEEL MAINTENANCE
Wheel maintenance consists of periodic
inspections. Check all parts for damage and
make sure that wheel nuts are tightened to the
proper torque. In the case of a new vehicle, or
after a wheel installation, stud nuts should be
tightened every 100 miles (160-km) for the first
500 miles (800-km) to allow setting in of
clamping surfaces.
Wheel studs and nuts must be kept free from
grease and oil. No lubricant whatsoever should
be used. Cleanliness of the wheel and its rotor
mating surfaces is important for proper wheel
mounting.
However, for hub mounted wheels, it is
recommended to add some rust protection
lubricant on the pilot diameter of the hub (to
facilitate future removal).
It is also important that wheel stud nuts be
tightened alternately on opposite sides of the
wheel. Refer to Figure 2 for the suggested
tightening sequence.
2.1 INSPECTION
Tighten stud nuts progressively as shown in
Figure 2. The final tightening should be done
with a torque wrench. Tighten stud nuts to 450 -
500 lbf-ft (610 - 680 Nm) for aluminum as well
as steel wheels.

2.2 SINGLE WHEEL REMOVAL
1. Stop engine and apply parking brake.
2. Loosen wheel nuts about one turn (do not
remove the nuts). This is not necessary if
equipped with hydraulic powered gun.
