8-Stud — Dual Rear Wheels
• Dual wheels are flat-mounted and center-piloted. The lug nuts are a two-piece
assembly. 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 tightening, to ensure wheel
centering and maximum 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 diameter of the two individual tires must be compared. If there is a
significant difference, the larger tire should be installed in a front location. 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
specifications 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.
To Stow The Flat Or Spare
NOTE: Vehicles equipped with aluminum wheels cannot be stored under the
vehicle because the wheel retainer will not fit through the wheel pilot hole. Secure
the flat tire in the bed of the truck.
Have the flat tire repaired or replaced
immediately.
