Tire Sidewall Labeling
Useful information about a tire is molded into its
sidewall. The examples below show a typical
passenger car tire and a compact spare tire
sidewall.(A) Tire Size:The tire size is a combination of
letters and numbers used to define a particular
tire’s width, height, aspect ratio, construction type
and service description. See the “Tire Size”
illustration later in this section for more detail.
(B) DOT (Department of Transportation):The
Department of Transportation (DOT) code
indicates that the tire is in compliance with the
U.S. Department of Transportation Motor Vehicle
Safety Standards.
(C) Tire Identication Number (TIN):The letters
and numbers following DOT code are the Tire
Identification Number (TIN). The TIN shows
the manufacturer and plant code, tire size, and
date the tire was manufactured. The TIN is
molded onto both sides of the tire, although only
one side may have the date of manufacture.
Passenger Car Tire Example
320

(B) Tire Ply Material:The type of cord and
number of plies in the sidewall and under the tread.
(C) Tire Identication Number (TIN):The Tire
Identification Number (TIN). The TIN shows
the manufacturer and plant code, tire size, and
date the tire was manufactured. The TIN is
molded onto both sides of the tire, although only
one side may have the date of manufacture.
(D) Maximum Cold Ination Load
Limit:Maximum load that can be carried and the
maximum pressure needed to support that
load. SeeCompact Spare Tire on page 344and
Loading Your Vehicle on page 249.
(E) Tire Ination:The temporary use tire or
compact spare tire should be inflated to 60 psi
(420 kPa). For more information on tire pressure
and inflation seeInflation - Tire Pressure on
page 326.
(F) Tire Size:A combination of letters and
numbers define a tire’s width, height, aspect ratio,
construction type and service description. The
letter T as the first character in the tire size means
the tire is for temporary use only.Tire Size
The following illustration shows an example of a
typical passenger car tire size.
(A) Passenger (P-Metric) Tire:The United
States version of a metric tire sizing system. The
letter P as the first character in the tire size
means a passenger vehicle tire engineered to
standards set by the U. S. Tire and Rim
Association.
(B) Tire Width:The three-digit number indicates
the tire section width in millimeters from sidewall
to sidewall.
(C) Aspect Ratio:A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is 70, as
shown in item C of the illustration, it would mean
that the tire’s sidewall is 70% as high as it is wide.
322

Passenger (P-Metric) Tire:A tire used on
passenger cars and some light duty trucks and
multipurpose vehicles.
Recommended Ination Pressure:Vehicle
manufacturer’s recommended tire inflation
pressure as shown on the tire placard. See
Inflation - Tire Pressure on page 326andLoading
Your Vehicle on page 249.
Radial Ply Tire:A pneumatic tire in which
the ply cords that extend to the beads are laid at
90 degrees to the centerline of the tread.
Rim:A metal support for a tire and upon which
the tire beads are seated.
Sidewall:The portion of a tire between the tread
and the bead.
Speed Rating:An alphanumeric code assigned
to a tire indicating the maximum speed at
which a tire can operate.
Traction:The friction between the tire and the
road surface. The amount of grip provided.
Tread:The portion of a tire that comes into
contact with the road.Treadwear Indicators:Narrow bands, sometimes
called wear bars, that show across the tread of a
tire when only 1/16 inch (1.6 mm) of tread remains.
SeeWhen It Is Time for New Tires on page 329.
UTQGS (Uniform Tire Quality Grading
Standards):A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings
are determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. SeeUniform
Tire Quality Grading on page 332.
Vehicle Capacity Weight:The number of
designated seating positions multiplied by 150 lbs
(68 kg) plus the rated cargo load. SeeLoading
Your Vehicle on page 249.
Vehicle Maximum Load on the Tire:Load on an
individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.
Vehicle Placard:A label permanently attached to
a vehicle showing the vehicle’s capacity weight
and the original equipment tire size and
recommended inflation pressure. See “Tire and
Loading Information Label” underLoading
Your Vehicle on page 249.
325

When It Is Time for New Tires
One way to tell when it
is time for new tires is
to check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.You need a new tire if any of the following
statements are true:•You can see the indicators at three or more
places around the tire.
•You can see cord or fabric showing through
the tire’s rubber.
•The tread or sidewall is cracked, cut, or
snagged deep enough to show cord or fabric.
•The tire has a bump, bulge, or split.
•The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
329

Buying New Tires
GM has developed and matched specific tires for
your vehicle. If you need replacement tires,
GM strongly recommends that you get tires that
are the same size, brand, load range, speed rating,
and construction type (radial and bias-belted
tires) as your vehicle’s original tires. This way, your
vehicle will continue to have tires that are
designed to give the same performance and
vehicle safety, during normal use, as the original
tires. SeeTire Sidewall Labeling on page 320
for additional information.{CAUTION:
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes, brands, or types (radial
and bias-belted tires), the vehicle may not
handle properly, and you could have a
crash. Using tires of different sizes,
brands, or types may also cause damage
to your vehicle. Be sure to use the correct
size, brand, and type of tires on all
wheels. It is all right to drive with your
compact spare temporarily, as it was
developed for use on your vehicle. See
Compact Spare Tire on page 344.
330

{CAUTION:
If you use bias-ply tires on your vehicle,
the wheel rim anges could develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly, causing
a crash. Use only radial-ply tires with the
wheels on your vehicle.
Your vehicle’s original equipment tires are listed
on the Tire and Loading Information Label.
This label is attached to the vehicle’s center pillar
(B-pillar). SeeLoading Your Vehicle on page 249,
for more information about the Tire and Loading
Information Label.
Different Size Tires and Wheels
If you add wheels or tires that are a different
size than your original equipment wheels and
tires, this may affect the way your vehicle
performs, including its braking, ride and handling
characteristics, stability, and resistance to rollover.Additionally, if your vehicle has electronic systems
such as, anti-lock brakes, traction control, and
electronic stability control, the performance of these
systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
GM certied technician.
SeeBuying New Tires on page 330and
Accessories and Modifications on page 264for
additional information.
331

Tire Chains
Notice:Use tire chains only where legal and
only when you must. Use only SAE Class “S”
type chains that are the proper size for your
tires. Install them on the front tires and 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 your 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
your vehicle.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will create 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 out of the traffic lane.A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes flat, the next part shows how to use the
jacking equipment to change a flat tire safely.
335

Storing a Flat or Spare Tire
and Tools
{CAUTION:
Storing a jack, a tire, or other equipment
in the passenger compartment of the
vehicle could cause injury. In a sudden
stop or collision, loose equipment could
strike someone. Store all these in the
proper place.
To store a flat or compact spare tire and tools, do
the following:
1. Store the flat tire or the compact spare in the
compact spare tire compartment.
2. Secure the retainer.
3. Store the tools securely in the foam tray and
place the tray back in the cargo area.
4. Replace the trim cover.
The compact spare tire is for temporary use only.
Replace the compact spare tire with a full-size
tire as soon as you can. SeeCompact Spare Tire
on page 344.
Compact Spare Tire
Although the compact spare tire was fully inflated
when your vehicle was new, it can lose air
after a time. Check the inflation pressure regularly.
It should be 60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make
sure your spare tire is correctly inflated. The
compact spare is made to perform well at speeds
up to 50 mph (80 km/h), so you can finish your
trip and have your full-size tire repaired or replaced
where you want. Of course, it is best to replace
your spare with a full-size tire as soon as you can.
Your spare will last longer and be in good shape
in case you need it again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your vehicle.
