Vehicle Care 285
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. Some
commercial truck tires may not have
treadwear indicators. SeeTire
Inspection 0282 and
Tire Rotation 0282 for additional
information.
The rubber in tires ages over time.
This also applies to the spare tire,
if the vehicle has one, even if it is
never used. Multiple factors
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. GM recommends that
tires, including the spare if
equipped, be replaced after six
years, regardless of tread wear. To
identify the age of a tire, use the tire
manufacture date which is the last
four digits of the DOT Tire
Identification Number (TIN) which is
molded into one side of the tire
sidewall. The first two digits
represent the week (01-52) and the
last two digits, the year. For example, the third week of the year
2010 would have a four-digit DOT
date of 0310.
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle. Park
a vehicle that will be stored for at
least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be free
of grease, gasoline, or other
substances that can deteriorate
rubber.
Parking for an extended period can
cause flat spots on the tires that
may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires or
raise the vehicle to reduce the
weight from the tires.
Buying New Tires
GM has developed and matched
specific tires for the vehicle. The
original equipment tires installed
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec)
system rating. When
replacement tires are needed,
GM strongly recommends
buying tires with the same TPC
Spec rating.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of the
vehicle, including brake system
performance, ride and handling,
traction control, and tire
pressure monitoring
performance. GM's TPC Spec
number is molded onto the tire's
sidewall near the tire size. If the
tires have an all-season tread
design, the TPC Spec number
will be followed by MS for mud
and snow. See
Tire Sidewall
Labeling 0271 for additional
information.
GM recommends replacing worn
tires in complete sets of four (six
for dual rear wheels). Uniform

tread depth on all tires will help
to maintain the performance of
the vehicle. Braking and
handling performance may be
adversely affected if all the tires
are not replaced at the same
time. If proper rotation and
maintenance have been done,
all four tires (six for dual rear
wheels) should wear out at
about the same time. SeeTire
Rotation 0282 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.
(Continued)
Warning (Continued)
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.
{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
(Continued)
Warning (Continued)
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.
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 0278.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. See Vehicle Load Limits
0 172 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 0285 and
Accessories and Modifications
0 230.
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.
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:

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
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(Continued)
Caution (Continued)
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
0 269. 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

5. Pull the spare tire out fromunder the vehicle.
6. Tilt the tire toward the vehiclewith some slack in the cable to
access the tire/wheel retainer.
Tilt the retainer and pull it
through the center of the wheel
along with the cable and
spring. 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.

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 Pressure0277
and Vehicle Load Limits 0172. For
instructions on how to remove,
install, or store a spare tire, see Tire
Changing 0292.
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 0271. 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.
