WHEEL AND TIRE TORQUE
SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been re-
moved and reinstalled on the vehicle, the lug
nuts/bolts should be torqued using a properly
calibrated torque wrench using a high quality
six sided (hex) deep wall socket.
Torque Specifications
All wheel nuts should be tightened occasion-
ally to eliminate the possibility of wheel studs
being sheared or the bolt holes in the wheels
becoming elongated. This is especially im-
portant during the first few hundred miles/
kilometers of operation to allow the wheel
nuts to become properly set. All wheel nuts
should first be firmly seated against the
wheel. The wheel nuts should then be tight-
ened to recommended torque. Tighten the
wheel nuts to final torque in increments.
Progress around the bolt circle, tightening
the wheel nut opposite to the wheel nut justpreviously tightened until final torque is
achieved. Ensure that the socket is fully en-
gaged on the lug nut/bolt (do not insert it
halfway).

lowing chart:

8-Stud — Dual Rear Wheels
• Dual wheels are flat-mounted and center-
piloted. The lug nuts are a two-piece as-
sembly. When the tires are being rotated or
replaced, clean these lug nuts and add two
drops of oil at the interface between the hex
and the washer. • Slots in the wheels will assist in properly
orienting the inner and outer wheels. Align
these slots when assembling the wheels for
best access to the tire valve on the inner
wheel. The tires of both dual wheels must
be completely off the ground when tighten-
ing, to ensure wheel centering and maxi-
mum wheel clamping.

• Dual wheel models require a special heavy-duty lug nut tightening adapter (included
with the vehicle) to correctly tighten the lug
nuts. Also, when it is necessary to remove
and install dual rear wheels, use a proper
vehicle lifting device.
NOTE:
When installing a spare tire as part of a dual
rear wheel end combination, the tire diam-
eter of the two individual tires must be com-
pared. If there is a significant difference, the
larger tire should be installed in a front loca-
tion. The correct direction of rotation for dual
tire installations must also be observed. These dual rear wheels should be tightened as
follows:
1. Tighten the wheel nuts in the numbered
sequence to a snug fit. 2. Retighten the wheel nuts in the same
sequence to the torques listed in the
table. Go through the sequence a second
time to verify that specific torque has
been achieved. Retighten to specifica-
tions at 100 miles (160 km) and after
500 miles (800 km).
• It is recommended that wheel stud nuts be kept torqued to specifications at all times.
Torque wheel stud nuts to specifications at
each lubrication interval.
