WARNING!(Continued)
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to “Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
• Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
• Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
• When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.

WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
•Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
(Continued)
WARNING! (Continued)
•Never start or run the engine with the vehicle on a
jack.
• Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
• Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely
careful of motor traffic.
• To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.

CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.
1. If equipped, remove the spare wheel, jack, and tools from storage.
2. Using the wheel wrench, loosen, but do not remove, the wheel nuts by turning them counterclockwise one
turn while the wheel is still on the ground. 3. When changing the front wheel, assemble the jack
drive tube to the jack and connect the drive tube to the
extension tube. Place the jack under the axle as close to
the tire as possible with the drive tubes extending to
the front. Connect the jack tube extension and wheel
wrench.

When changing a rear wheel, assemble the jack drive
tube to the jack and connect the drive tube to the
extension tube. Securely place the jack under the sway
bar bracket (unless both tires are flat on one side, then
place jack under shock bracket) facing forward in vehicle.
Connect the jack tube extension and lug wrench.Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
NOTE:
If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to use the
jack drive tube in order to lower the jack.
4. By rotating the wheel wrench clockwise, raise the vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause a collision. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install the spare wheel and wheel nuts with the cone shaped
end of the nuts toward the wheel on single rear wheel

(SRW) models. On dual rear wheel models (DRW) the
lug nuts are a two-piece assembly with a flat face.
Lightly tighten the nuts. To avoid risk of forcing the
vehicle off the jack, do not fully tighten the nuts until
the vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts using a crisscross pattern. For the proper lug nut
torque specifications refer to “Wheel and Tire Torque
Specifications” in this section. If in doubt about the
correct tightness, have them checked with a torque
wrench by your authorized dealer or at a service
station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Al-
ways stow the jack parts and the extra tire and wheel
in the places provided. 7. Install wheel center cap (if equipped) and remove
wheel blocks. Do not install chrome or aluminum
wheel center caps on the spare wheel. This may result
in cap damage.
8. Lower the jack to its fully closed position. If the jack will not lower by turning the dial (thumbwheel) by
hand, it may be necessary to use the jack drive tube in
order to lower the jack. Stow the replaced tire, jack,
and tools as previously described.
9. Adjust the tire pressure when possible.
Hub Caps/Wheel Covers — If Equipped
The hub caps must be removed before raising the vehicle
off the ground.
428 WHAT TO DO IN EMERGENCIES
Page 432 of 546

Replace the wheel skins first using a rubber mallet. When
replacing the hub caps, tilt the cap retainer over the lug
nut bolt circle and strike the high side down with a
rubber mallet. Be sure that the hub caps and wheel skins
are firmly seated around the wheel.
Dual Rear Wheels
Slots in the wheels will assist in properly orienting the
inner and outer wheels. Align these slots when assem-
bling 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 insure
wheel centering and maximum wheel clamping.
Dual wheel models require a special heavy-duty lug nut
tightening adapter (included with the vehicle) to cor-
rectly 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 (if equipped) 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.
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.
• 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).
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builders Guide for information
on stowing your spare tire (if equipped).
