maintenance have been done,
all four tires (six for dual rear
wheels) should wear out at
about the same time. SeeTire
Rotation 0266 for information
on proper tire rotation. However,
if it is necessary to replace only
one axle set of worn tires, place
the new tires on the rear axle
(two for single rear wheels, four
for dual rear wheels).
{Warning
Tires could explode during
improper service. Attempting
to mount or dismount a tire
could cause injury or death.
Only your dealer or authorized
tire service center should
mount or dismount the tires.
{Warning
Mixing tires of different sizes,
brands, or types may cause
loss of control of the vehicle,
resulting in a crash or other
vehicle damage. Use the
correct size, brand, and type
of tires on all wheels.
This vehicle may have a
different size spare than the
road tires originally installed
on the vehicle. When new, the
vehicle included a spare tire
and wheel assembly with a
similar overall diameter as the
road tires and wheels, so it is
all right to drive on it. The
spare tire was developed for
use on this vehicle and will not
affect vehicle handling.{Warning
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H,
V, W, Y and ZR speed rated
tires. Never exceed the winter
tires’ maximum speed capability
when using winter tires with a
lower speed rating.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
load range, speed rating, and
construction (radial) as the
original tires.

Vehicle Care 271
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed.
SeeTire Pressure Monitor
System 0262.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. See Vehicle Load Limits
0 167 for the label location and
more information about the Tire
and Loading Information label.
Different Size Tires and
Wheels
If wheels or tires are installed that
are a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, electronic stability control, or All-Wheel Drive, the performance
of these systems can also be
affected.
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.
See Buying New Tires 0269 and
Accessories and Modifications
0 213.
Uniform Tire Quality
Grading
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration (NHTSA), which grades tires by
treadwear, traction, and
temperature performance. This
applies only to vehicles sold in
the United States. The grades
are molded on the sidewalls of
most passenger car tires. The
Uniform Tire Quality Grading
(UTQG) system does not apply
to deep tread, winter tires,
compact spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production
tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.

274 Vehicle Care
Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
Tire chains used on a vehicle
without the proper amount of
clearance can cause damage to
the brakes, suspension, or other
vehicle parts. The area damaged
by the tire chains could cause you
to lose control of the vehicle and
you or others may be injured in a
crash. To help avoid damage to(Continued)
Warning (Continued)
the vehicle, drive slowly, readjust,
or remove the device if it is
contacting the vehicle. Do not
spin the vehicle's tires. Follow the
manufacturer's instructions.
Caution
Use tire chains only where legal
and only when necessary. Use
chains that are the proper size for
the tires. Install them on the tires
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(Continued)
Caution (Continued)
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
0 253. If air goes out of a tire, it is
much more likely to leak out slowly.

5. Remove the wheel wrench,extension(s), and hoist handle
assembly from the hoist shaft.
6. When the tire has been
lowered, pull it closer to reach
the tire retainer and pull it up
through the wheel opening.
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.

2. Hoist Handle
3. Extension(s) 4. Wheel Wrench
5. Jack Handle
1. Do a safety check before
proceeding. See If a Tire Goes
Flat 0274.
2. Loosen all the wheel nuts with the wheel wrench. 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
wrench (4).
Rear Flat: Assemble the
jack (1) together with the jack
handle (5), two extensions (3),
and the wheel wrench (4).

2. Pull the retaining bar throughthe center of the wheel, making
sure it is properly attached.
3. Pull the wheel toward the rear of the vehicle, keeping the
cable tight.
4. Open the passenger side rear door.
5. Insert the chisel end of the hoist handle, on an angle,
through the hole in the rear
floor panel above the bumper.
6. Turn the wheel wrench clockwise to fully raise the tire
against the underside of the
vehicle. Continue turning the
wheel wrench until the tire is
secure and the cable is tight. Two clicks should occur. The
spare tire hoist cannot be
overtightened.
7. Make sure the tire is stored
securely. Push, pull (1), and
then try to turn (2) the tire.
If the tire moves, use the wheel
wrench to tighten the cable.
Two clicks mean the tire is up
all the way.
8. Return the jacking equipment to 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 Pressure0261
and Vehicle Load Limits 0167. 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.
