Ination - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right.
It is not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazardsA vehicle specific Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle’s original equipment tires and the
correct inflation pressures for your tires when they
are cold. The recommended cold tire inflation
pressure, shown on the label, is the minimum
amount of air pressure needed to support
your vehicle’s maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example of
the Tire and Loading Information label, see
Loading Your Vehicle on page 261. How you load
your vehicle affects vehicle handling and ride
comfort. Never load your vehicle with more weight
than it was designed to carry.
When to Check
Check your tires once a month or more.
Do not forget to check the pressure of the spare
tire. SeeSpare Tire on page 382for additional
information.
How to Check
Use a good quality pocket-type gage to check
tire pressure. You cannot tell if your tires are
properly inflated simply by looking at them.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 358
andWheel Replacement on page 362for
more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, use the ratchet/wheel wrench to tighten the
cable. SeeChanging a Flat Tire on page 366.
If your vehicle has dual rear wheels, also see
Dual Tire Operation on page 355.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
first rotation is the most important. SeeScheduled
Maintenance (Gasoline Engine) on page 405.If your vehicle has single rear wheels, always use
the correct rotation patterns shown here when
rotating your vehicle’s tires. Do not include
the spare tire in the tire rotation, if the spare
tire/wheel assembly does not match your vehicle’s
road tires and wheels in size and type.
Single Rear Wheels
356

If the tires have an all-season tread design,
the TPC spec number will be followed by a MS,
for mud and snow. SeeTire Sidewall Labeling
on page 347for 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 your
vehicle’s wheels.
{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.
If you must replace your vehicle’s tires with
those that do not have a TPC Spec number,
make sure they are the same size, load range,
speed rating, and construction type (radial
and bias-belted tires) as your vehicle’s
original tires.
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 261,
for more information about the Tire and Loading
Information label.

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-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.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA,
A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured under
controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.
Warning:The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
361

Tire Chains
{CAUTION:
If your vehicle has dual wheels or
P245/75R16 or LT245/75R16 size tires,
do not use tire chains. They can damage
your vehicle because there is not
enough clearance. 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 your vehicle
and you or others may be injured in
a crash.
Use another type of traction device only
if its manufacturer recommends it for
use on your vehicle and tire size
combination and road conditions.
Follow that manufacturer’s instructions.
CAUTION: (Continued)
CAUTION: (Continued)
To help avoid damage to your vehicle,
drive slowly, readjust, or remove the
device if it is contacting your vehicle,
and do not spin the vehicle’s wheels.
If you do nd traction devices that will t,
install them on the rear tires.
Notice:If your vehicle does not have
dual wheels and has a tire size other than
P245/75R16 or LT245/75R16, use tire chains
only where legal and only when you must.
Use chains that are the proper size for your
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 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.
364

Spare Tire
Your vehicle, when new, had a fully inflated
spare tire. A spare tire may lose air over time,
so check its inflation pressure regularly. See
Ination - Tire Pressure on page 354andLoading
Your Vehicle on page 261for information regarding
proper tire inflation and loading your vehicle. For
instructions on how to remove, install or store a
spare tire, seeRemoving the Flat Tire and Installing
the Spare Tire on page 370andStoring a Flat or
Spare Tire and Tools on page 380.
Your vehicle may have a different size spare tire
than the road tires originally installed on your
vehicle. This spare tire was developed for use
on your vehicle, so it is all right to drive on it.
After installing the spare tire on your vehicle,
you should stop as soon as possible and make
sure the spare tire is correctly inflated. Have
the damaged or flat road tire repaired or
replaced as soon as you can and installed
back onto your 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 your spare tire and
its wheel together. If your vehicle has a spare
tire that does not match your vehicle’s original road
tires and wheels in size and type, do not include
the spare tire in the tire rotation.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its
best if it is cleaned often. Although not always
visible, dust and dirt can accumulate on your
upholstery. Dirt can damage carpet, fabric, leather,
and plastic surfaces. Regular vacuuming is
recommended to remove particles from your
upholstery. It is important to keep your upholstery
from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes
of heat that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and
garments that transfer color to your home
furnishings may also transfer color to your
vehicle’s interior.
