The Tire and Loading Information
label indicates the original
equipment tires on the vehicle. See
Vehicle Load Limits on page 9‑10
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, and electronic stability
control, 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 on
page 10‑66 andAccessories and
Modifications on page 10‑3.
Uniform Tire Quality
Grading
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200 Traction AA
Temperature A
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,

{WARNING
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Notice: The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration,
headlamp aim, bumper height,
vehicle ground clearance, and tire
or tire chain clearance to the
body and chassis.
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

WARNING (Continued)
crash. To help avoid damage to
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.
Notice: Use tire chains only
where legal and only when you
must. 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 you can hear the chains
contacting 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.

10-72 Vehicle Care
For Cutaway models with LT245/
75R16, LT225/75R16 or LT215/
85R16 size single or dual rear tires,
use Low Profile Z-Chain or
SAE Class S cables.
For Cargo or Passenger models
with P245/70R17, 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. 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.

4. 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.
5. Put the spare tire near the flat tire.
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 on page 10‑72 for more
information.
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 (A) together with the jack
handle (B), one or two jack
handle extensions (D), and the
wheel wrench (E).

10-84 Vehicle Care
Full-Size Spare Tire
This vehicle, when new, may have
had a fully-inflated spare tire.
A spare tire may lose air over time,
so check its inflation pressure
regularly. SeeTire Pressure on
page 10‑57 andVehicle Load Limits
on page 9‑10 for information
regarding proper tire inflation and
loading the vehicle. For instruction
on how to remove, install or store a
spare tire, see “Removing the Flat
Tire and Installing the Spare Tire”
and “Storing a Flat or Spare Tire
and Tools” underTire Changing on
page 10‑74. After installing the spare tire on the
vehicle, you should stop as soon as
possible and make sure 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 as soon as you
can and installed back onto the
vehicle. This way, a spare tire will
be available in case you need it
again. Do not mix tires and wheels
of different sizes, because they will
not fit. Keep the spare tire and its
wheel together.
Jump Starting
For more information about the
vehicle battery, see
Battery on
page 10‑30.
If the vehicle battery has run down,
you may want to use another
vehicle and some jumper cables to
start your vehicle. Be sure to use
the following steps to do it safely.
{WARNING
Batteries can hurt you. They can
be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you.
