WHEELS
AND
TIRES
22 - 7 move and install dual rear wheels only when the
proper wrench is available.
INSTALLATION
The tires on both wheels must be completely raised
off the ground when tightening the lug nuts (Fig. 5).
This will ensure correct wheel centering and maxi mum wheel clamping.
HUB
^
INWARD
Fig.
5 Flange Centering And
Alignment
A 1
1/8-inch
diameter flanged-type wheel lug nut
with right-hand threads is used for retaining dual rear wheels on the hubs. A special, heavy duty wheel lug nut wrench is necessary to correctly tighten the nuts with the required torque (Fig. 4).
The dual rear wheel lug nuts should be tightened
according to the following procedure:
• Tighten the wheel lug nuts in the numbered se
quential pattern until they are snug tight (Fig. 4).
• Tighten the wheel lug nuts in the numbered se
quential pattern to 440 N#m (325 ft-lb) torque.
• Tighten the lug nuts in the numbered sequential
pattern a second time to the specified torque. This will ensure that the wheels are thoroughly mated. • Retighten the lug nuts to the specified torque after 100 miles (160 kilometers). Also retighten after 500
miles (800 kilometers) of vehicle operation.
The wheel lug nuts should be tightened with
the specified torque at every chassis lubrication
interval thereafter.
WHEEL REPLACEMENT
Wheels must be replaced if they have:
• Excessive runout
• Bent or dented
• Leak air through welds
• Have damaged bolt holes Wheel repairs employing hammering, heating, or
welding are not allowed. Original equipment wheels are available through
your dealer. Replacement wheels from any other source should be equivalent in: • Load carrying capacity
• Diameter
® Width
• Offset
• Mounting configuration
Failure to use equivalent replacement wheels may
affect the safety and handling of your vehicle. Re
placement with used wheels is not recommended.
Their service history may have included severe treat ment.
Refer to the Specifications Chart for informa
tion regarding above requirements.

TIRE AND WHEEL BALANCE
It is recommended that a two plane dynamic bal
ancer be used when a wheel and tire assembly re
quire balancing. Static should be used only when a
two plane balancer is not available. For static imbalance, find location of heavy spot
causing imbalance. Counter balance wheel directly
opposite the heavy spot. Determine weight required
to counterbalance the area of imbalance. Place half of this weight on the inner rim flange and the other
half on the outer rim flange (Fig. 6, Fig. 7). Off-ve
hicle balancing is necessary. Wheel balancing can be accomplished with either
on or off vehicle equipment. When using on-vehicle
balancing equipment, follow these precautions: • Limited-slip rear axle differential, remove the op
posite wheel/tire • Before balancing the wheels/tires on a vehicle
equipped with a transfer case, disconnect the drive shafts
MATCH
MOUNTING
Wheels and tires are match mounted at the factory.
This means that the high spot of the tire is matched
to the low spot on the wheel rim. This technique is used to reduce run-out in the wheel/tire assembly.
The high spot on the tire is marked with a paint mark or a bright colored adhesive label on the out
board sidewall. The low spot on the rim is at the
valve stem location on the wheel rim. Before dismounting a tire from its wheel, a refer
ence mark should be placed on the tire at the valve stem location. This reference will ensure that it is re
mounted in the original position on the wheel. (1) Measure the total indicator runout on the cen
ter of the tire tread rib. Record the indicator reading.
