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.
Passenger Car Tire Example
5-62

(A) Temporary Use Only:The compat spare tire or
temporary use tire has a tread life of approximately
3,000 miles (5 000 km) and should not be driven
at speeds over 65 mph (105 km/h). The compact spare
tire is for emergency use when a regular road tire
has lost air and gone at. SeeCompact Spare Tire on
page 5-89andIf a Tire Goes Flat on page 5-77.
(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
Identication 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 5-89andLoading Your Vehicle on page 4-33.
(E) Tire Ination:The temporary use tire or compact
spare tire should be inated to 60 psi (420 kPa).
For more information on tire pressure and ination see
Ination - Tire Pressure on page 5-68.
Compact Spare Tire Example
5-64

When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly inated
simply by looking at them. Radial tires may look
properly inated even when they’re underinated. Check
the tire’s ination pressure when the tires are cold.
Cold means your vehicle has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press
the tire gage rmly onto the valve to get a pressure
measurement. If the cold tire ination pressure matches
the recommended pressure on the Tire and Loading
Information label, no further adjustment is necessary. If
the ination pressure is low, add air until you reach
the recommended amount.
If you overll the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck the
tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Tire Pressure Monitor System
The tire ination monitor system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you if a tire is
low – but it does not replace normal tire maintenance.
SeeTires on page 5-61.
When the LOW TIRE light comes on the instrument
panel, stop as soon as you can and check all the tires
for damage. If a tire is at, seeIf a Tire Goes Flat
on page 5-77. Also, check the tire pressure in all four
tires as soon as possible. SeeInation - Tire Pressure
on page 5-68.
In order for the tire ination system to function properly,
the vehicle must be driven between 45 and 90 minutes
before the system determines the tire pressure in
each tire. The driving time may be longer depending on
an individual’s driving habits. The data does not have
to be accumulated during a single trip. Once determined,
the system will store the tire pressures until the
system is reset.
The system normally takes 15 to 20 minutes of driving
time in each of three speed ranges to determine tire
pressures. The speed ranges are 15 to 40 mph (25 to
65 km/h), 40 to 65 mph (65 to 105 km/h) and above
65 mph (105 km/h). When the storage of the tire ination
information is complete, the LOW TIRE light will come on
the instrument panel after two to eight minutes if one tire
is inated 12 psi (83 kPa) less than the other three tires.
5-69

When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label.
Reset the Tire Ination Monitor System. SeeTire
Pressure Monitor System on page 5-69.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-103.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off. See “Changing a Flat
Tire” in the Index.
5-71

{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels. It’s all right to drive with your
compact spare temporarily, it was developed
for use on your vehicle. See “Compact Spare
Tire” in the index.
{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.
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, 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
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use 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.

Removing the Spare Tire and Tools
The equipment you will need is in the trunk.
1. Turn the center nut on
the compact spare tire
cover counterclockwise
to remove it. Then
lift and remove
the cover. See
Compact Spare Tire on
page 5-89for more
information about the
compact spare tire.
2. Remove the compact spare tire.
5-79

Removing the Flat Tire and Installing
the Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts,
but do no remove them yet.
2. Turn the jack handle clockwise to raise the jack
lift head.3. For jacking at the vehicle’s front location, put the
jack lift head (C) about 6 inches (15 cm) from the
rear edge of the front wheel opening (B) or just
behind the two bolts (A) as shown.
5-82

For jacking at the vehicle’s rear location, put the
jack lift head (B) about 5 inches (13 cm) from
the front edge of the rear wheel opening (C) or just
behind the off-set (A) as shown.4. Put the compact spare tire near you.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get
under a vehicle when it is supported only by
a jack.
5-83

{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to t the
jack lift head into the proper location before
raising the vehicle.5. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground for the compact spare tire to t under the
vehicle.
6. Remove all wheel nuts and take off the at tire.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
