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.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
of operation to allow the wheel nuts to become properly
set. All nuts should first be firmly seated against the
414 WHAT TO DO IN EMERGENCIES
wheel. The nuts should then be tightened to recom-
mended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening
the nut opposite to the nut just previously tightened until
final torque is achieved. Recommended torques are
shown in the following chart.

To Stow The Flat Or Spare
NOTE: 1500 Standard and Quad Cab 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 immedi-
ately.
WARNING!
A loose tire thrown forward in a collision or hard
stop could injure the occupants in the vehicle. Have
the deflated (flat) tire repaired or replaced immedi-
ately.
Turn the wheel so that the valve stem is down. Slide the
wheel retainer through the center of the wheel and
position it properly across the wheel opening.
For convenience in checking the spare tire inflation, stow
with the valve stem toward the rear of the vehicle.
Attach the wheel wrench to the extension tube. Rotate the
winch mechanism until the wheel is drawn into place
against the underside of the vehicle. Continue to rotate
until you feel the winch mechanism slip or click 3 or 4
times. It cannot be overtightened. Push against the tire
several times to be sure it is firmly in place.
