The vehicle needs new tires 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.
The rubber in tires degrades over
time, even if they are not being used.
This is also true for the spare tire,
if the vehicle has one. Multiple
conditions affect how fast this aging
takes place, including temperatures,
loading conditions, and inflationpressure maintenance. With proper
care and maintenance tires typically
wear out before they degrade due to
age. If you are unsure about the
need to replace the tires as they get
older, consult the tire manufacturer
for more information.
Buying New Tires
GM has developed and matched
specific tires for your vehicle. The
original equipment tires installed
on your vehicle, when it was new,
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec) system
rating. If you need replacement
tires, GM strongly recommends
that you get tires with the same
TPC Spec rating. 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.GM’s exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of your
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 an MS for mud and snow.
SeeTire Sidewall Labeling
on page 9-49for additional
information.
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 9-61andTire Rotation on
page 9-61for 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
(Continued)
WARNING (Continued)
spare temporarily, as it was
developed for use on your
vehicle. SeeCompact Spare
Tire on page 9-83.
{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.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 9-56.
Your vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label.
SeeVehicle Load Limits on
page 8-12, for more information
about the Tire and Loading
Information Label and its location
on your vehicle.

Tire Sealant and
Compressor Kit
{WARNING
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness and
even death. Never run the engine
in an enclosed area that has no
fresh air ventilation. For more
information, seeEngine Exhaust
on page 8-25.
{WARNING
Over-inflating a tire could cause
the tire to rupture and you or
others could be injured. Be sure to
read and follow the tire sealant and
compressor kit instructions and
inflate the tire to its recommended
pressure. Do not exceed the
recommended pressure.
{WARNING
Storing the tire sealant and
compressor kit 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 the tire sealant
and compressor kit in its original
location.If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire, tire changing equipment,
and on some vehicles there may not
be a place to store a tire.
The tire sealant and compressor
can be used to temporarily seal
punctures up to 6 mm (
1⁄4inch) in the
tread area of the tire. It can also be
used to inflate an under inflated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire
is too severely damaged for the tire
sealant and compressor kit to be
effective. SeeRoadside Assistance
Program on page 12-6.
Read and follow all of the tire
sealant and compressor kit
instructions.

Notice:Make sure that the
jack lift head is in the correct
position or you may damage your
vehicle. The repairs would not
be covered by your warranty.
3. Position the jack lift head at the
jack location nearest the flat tire.
The location is indicated by a
mark on the bottom edge of the
vehicle. The jack must not be
used in any other position.
Raise the jack until it engages
with the jacking point.4. Put the compact spare tire
near you.
{WARNING
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.
{WARNING
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 fit the jack lift head into the
proper location before raising the
vehicle.5. Fit the jack handle extension
onto the jack by sliding the
hook through the end of the jack.
