Tires
Your new vehicle comes with
high-quality tires made by a
leading tire manufacturer. If you
ever have questions about your
tire warranty and where to
obtain service, see your vehicle
Warranty booklet for details.
For additional information refer
to the tire manufacturer.
{WARNING
Poorly maintained and improperly
used tires are dangerous.
.Overloading your tires can
cause overheating as a result
of too much flexing. You
could have an air-out and a
serious accident. SeeVehicle
Load Limits on page 9‑22.
.Underinflated tires pose the
same danger as overloaded
tires. The resulting accident
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when your
tires are cold. See Tire
Pressure on page 10‑50.
(Continued)
WARNING (Continued)
.Overinflated tires are more
likely to be cut, punctured
or broken by a sudden
impact—such as when you
hit a pothole. Keep tires at
the recommended pressure.
.Worn, old tires can cause
accidents. If your tread is
badly worn, or if your tires
have been damaged,
replace them.

(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.
(G) TPC Spec (Tire
Performance Criteria
Specification)
:Original
equipment tires designed to
GM's specific tire performance
criteria have a TPC specification
code molded onto the sidewall.
GM's TPC specifications meet
or exceed all federal safety
guidelines.
Tire Designations
Tire Size
The following illustration shows
an example of a typical
passenger vehicle 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 60, as shown in
item C of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(D) Construction Code
:
A letter code is used to indicate
the type of ply construction in
the tire. The letter R means
radial ply construction; the
letter D means diagonal or bias
ply construction; and the letter B
means belted‐bias ply
construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carry capacity a tire is

Vehicle Care 10-53
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or
more of your tires is significantly
under‐inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on a
significantly under‐inflated tire
causes the tire to overheat and can
lead to tire failure. Under‐inflation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under‐inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start‐ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.

10-54 Vehicle Care
Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the vehicle's tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
on the instrument panel cluster.The low tire pressure warning light
comes on at each ignition cycle until
the tires are inflated to the correct
inflation pressure.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
may be an early indicator that the
air pressure in the tire(s) are getting
low and need to be inflated to the
proper pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for your
vehicle's tires when they are cold.
See
Vehicle Load Limits
on
page 9‑22, for an example of the
Tire and Loading Information label
and its location on your vehicle.
Also see Tire Pressure
on
page 10‑50.
Your vehicle's TPMS system can
warn you about a low tire pressure
condition but it does not replace
normal tire maintenance. See Tire
Inspection
on page 10‑57, Tire
Rotationon page 10‑57and Tireson
page 10‑43.
Notice: Liquid tire sealants could
damage the Tire Pressure Monitor
System (TPMS) sensors. Sensor
damage caused by using a tire
sealant is not covered by your
warranty. Do not use liquid tire
sealants.

Vehicle Care 10-55
TPMS Malfunction Light
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire warning light flashes for
about one minute and then stays on
for the remainder of the ignition
cycle. The TPMS malfunction light
comes on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause the
malfunction light to come on are:
.One of the road tires has been
replaced with the spare tire.
The spare tire does not have a
TPMS sensor. The TPMS
malfunction light should go off
once you re‐install the road tire
containing the TPMS sensor.
.The TPMS sensor matching
process was started but not
completed or not completed
successfully after rotating the
vehicle's tires. The TPMS
malfunction light should go off
once the TPMS sensor
matching process is performed
successfully. See“TPMS Sensor
Matching Process” later in this
section.
.One or more TPMS sensors are
missing or damaged. The TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer/
retailer for service.
.Replacement tires or wheels do
not match your vehicle's original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. See Buying
New Tires on page 10‑59.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.

10-56 Vehicle Care
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors or rotate the vehicle's tires,
the identification codes will need to
be matched to the new tire/wheel
position. The sensors are matched,
to the tire/wheel positions, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer/retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire's air pressure. When increasing
the tire's pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall.To decrease the tire's air-pressure
use the pointed end of the valve
cap, a pencil-style air pressure
gage, or a key.
You have two minutes to match
each tire and wheel position. If it
takes longer than two minutes to
match any tire and wheel position,
the matching process stops and
you will need to start over.
The TPMS matching process is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press and hold the RKE transmitter's Lock and Unlock
buttons at the same time, for
about three seconds. The horn
will sound twice to indicate the
receiver is ready for the sensor
matching process to begin. 4. Start with the driver side front
tire. The driver side turn signal
lamp comes on.
5. Remove the valve cap from the tire's valve stem. Activate the
TPMS sensor by increasing or
decreasing the tire's air pressure
for five seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to
30 seconds to sound, confirms
that the sensor identification
code has been matched to the
tire/wheel position.
6. Proceed to the passenger side front tire. The passenger side
front turn signal lamp comes on.
Repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire. The passenger side
rear turn signal lamp comes on.
Repeat the procedure in Step 5.
ProCarManuals.com

Vehicle Care 10-57
8. Proceed to the driver side reartire. The driver side rear turn
signal lamp comes on. Repeat
the procedure in Step 5.
The horn sounds two times to
indicate the sensor identification
code has been matched to the
driver side rear tire, and the
TPMS sensor matching process
is no longer active.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
11. Put the valve caps back on the valve stems.Tire Inspection
We recommend that you
regularly inspect your vehicle's
tires, including the spare tire,
if the vehicle has one, for signs
of wear or damage. See When It
Is Time for New Tires
on
page 10‑58
for more information.
Tire Rotation
Tires should be rotated every
8 000 to 13 000 km (5,000 to
8,000 miles). See Scheduled
Maintenance
on page 11‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new. Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
See
When It Is Time for New
Tires
on page 10‑58and Wheel
Replacement
on page 10‑64.
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here.
ProCarManuals.com

10-58 Vehicle Care
Do not include the compact
spare tire in the tire rotation.
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. SeeTire Pressure
on
page 10‑50
and Vehicle Load
Limits
on page 9‑22.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation
on page 10‑54.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications
on
page 12‑2
.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle.
In an emergency, use a cloth or a
paper towel to do this; but be sure
to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. See If a Tire Goes Flat
on page 10‑65.
When It Is Time for
New Tires
Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and road
conditions influence when you need
new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which appear when the
tires have only 1.6 mm (1/16 inch) or
less of tread remaining.
ProCarManuals.com

10-60 Vehicle Care
GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires
will help keep your vehicle
performing most like it did when
the tires were new. Replacing
less than a full set of tires can
affect the braking and handling
performance of your vehicle.
SeeTire Inspection
on page 10‑57
andTire Rotationon page 10‑57
for information on proper tire
rotation.
{WARNING
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 10‑73.
{WARNING
If you use bias-ply tires on the
vehicle, the wheel rim flanges
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 the 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.
ProCarManuals.com

Vehicle Care 10-61
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low‐pressure warning if non‐TPC
Spec rated tires are installed
on your vehicle. Non‐TPC
Spec rated tires may give a
low‐pressure warning that is
higher or lower than the proper
warning level you would get with
TPC Spec rated tires. SeeTire
Pressure Monitor System
on
page 10‑52
.
Your vehicle's original
equipment tires are listed on the
Tire and Loading Information
Label. See Vehicle Load Limits
on page 9‑22, for more
information about the Tire and
Loading Information Label and
its location on your vehicle.
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, rollover airbags,
traction control, and stability control,
the performance of these systems
can be affected.
{WARNING
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
Saturn specific wheel and tire
systems developed for your
vehicle, and have them properly
installed by a Saturn certified
technician.
