of the rear axle. Do not use
chains on the tires of the front
axle. Tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and follow
the chain manufacturer's
instructions. If the chains contact
the vehicle, stop and retighten
them. If the contact continues,
slow down until it stops. Driving
too fast or spinning the wheels
with chains on will damage the
vehicle.
For Cutaway models with LT245/
75R16 or LT225/75R16 size single
or dual rear tires, use Low Profile
Z-Chain or SAE Class S cables.
For Cargo or Passenger models
with LT225/75R16 or LT245/75R16
size tires, use Low Profile Z-Chain
cables. SAE Class S chains are not
recommended. If the vehicle has dual rear tires, do
not use individual tire chains. Use
tire chains that fit across both dual
tires.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. See
Tires
0 254. If air goes out of a tire, it is
much more likely to leak out slowly.
But if there ever is a blowout, here
are a few tips about what to expect
and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and

For a vehicle that was
completed from a cab and
chassis, refer to the information
from the body supplier/installer.
The spare tire is a full-size tire,
like the other tires on the
vehicle.
7. Put the spare tire near the flat tire.
8. Close the passenger side rear door.
Removing the Flat Tire and
Installing the Spare Tire
If the vehicle has plastic wheel nut
caps, loosen them by turning the
wheel wrench counterclockwise.
The wheel nut caps are designed to
remain with the center cap. Remove
the center cap.
If the wheel has a smooth center
piece, place the chisel end of the
wheel wrench in the slot on the
wheel and gently pry it out.

1. Do a safety check beforeproceeding. See If a Tire Goes
Flat 0275.
2. Turn the wheel wrench
counterclockwise to loosen all
the wheel nuts, but do not
remove them yet.
3. Assemble the jack and tools: Front Flat: Assemble the
jack (1) together with the jack
handle (5), one or two
extension(s) (3), and the wheel

9. Return the jacking equipmentto the proper location. Secure
the items and replace the jack
cover.
Full-Size Spare Tire
If this vehicle came with a full-size
spare tire, it was fully inflated when
new, however, it can lose air over
time. Check the inflation pressure
regularly. See Tire Pressure0262
and
Vehicle Load Limits 0157. For
instructions on how to remove,
install, or store a spare tire, see Tire
Changing 0276.
After installing the spare tire on the
vehicle, stop as soon as possible
and check that the spare is correctly
inflated. The spare tire is made to
perform well at speeds up to
112 km/h (70 mph) at the
recommended inflation pressure, so
you can finish your trip.
Have the damaged or flat road tire
repaired or replaced back onto the
vehicle, as soon as possible, so the
spare tire will be available in case it
is needed again. Do not mix tires and wheels of
different sizes, because they will not
fit. Keep the spare tire and its wheel
together.
If this vehicle has a spare tire that
does not match the original road
tires and wheels in size and type,
do not include the spare in the tire
rotation.
If equipped with a temporary use
full-size spare tire, it is indicated on
the tire sidewall. See
Tire Sidewall
Labeling 0256. The spare tire
should not be driven on over
112 km/h (70 mph), or 88 km/h
(55 mph) when pulling a trailer, at
the proper inflation pressure. Repair
and replace the road tire as soon as
it is convenient, and stow the spare
tire for future use.
