Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, for
signs of wear or damage.
SeeWhen It Is Time for New
Tires on page 9-56for more
information.
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). SeeScheduled
Maintenance on page 11-4.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that your vehicle
continues to perform most like it
did when the tires were new.
9-54 Vehicle Service and Care
2008 - Pontiac G8 Owner Manual

Any time you notice unusual
wear, rotate the 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 9-56andWheel
Replacement on page 9-61.
When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.The compact spare tire, if the
vehicle has one, is not included
in the tire rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures as shown on the Tire
and Loading Information label.
SeeInflation - Tire Pressure on
page 9-46andLoading the
Vehicle on page 8-28.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 9-51.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications
on page 10-2.{CAUTION
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 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 needed, to get all the rust
or dirt off. SeeChanging a
Flat Tire (V6 Engine) on
page 9-71.

When It Is Time for New
Tires
Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and
road conditions inuence when you
need new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which will appear
when the tires have only 1/16 inch
(1.6 mm) or less of tread remaining.You need 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 ination pressure maintenance.
With proper care and maintenance
tires typically wear out beforethey 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
specic 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
Specication (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.
9-56 Vehicle Service and Care
2008 - Pontiac G8 Owner Manual

GM’s exclusive TPC Spec system
considers over a dozen critical
specications 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 9-40for 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
and Rotation on page 9-54for
information on proper tire rotation.{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 the vehicle. Be
sure to use the correct size,
brand, and type of tires on
all wheels. It is all right to
drive with the compact
spare temporarily, as it was
developed for use on the
vehicle. SeeCompact Spare
Tire on page 9-79.{CAUTION
If you use bias-ply tires on
the 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 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.

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 gradesare 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 specied
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 signicantly from the
norm due to variations in driving
habits, service practices, and
differences in road
characteristics and climate.

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.
If a tire goes at, and your vehicle
has a compact spare tire, see
Changing a Flat Tire (V6 Engine) on
page 9-71. This information shows
you how to use the vehicle’s
tire changing equipment and how to
change a at tire safely.{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.
Tire Sealant and
Compressor Kit
If your vehicle has a factory installed
Tire Sealant and Compressor kit,
there is no spare tire, no tire
changing equipment and no place to
store a tire.If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place and stopping.
1. Turn on the hazard warning
ashers. SeeHazard Warning
Flashers on page 4-4.
2. Park your vehicle. Set the
parking brake rmly and put the
shift lever in PARK (P). See
Shifting Into Park (Automatic
Transmission) on page 8-10.
3. Turn off the engine.
4. Inspect the at tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a puncture larger than a
14inch (6 mm), the tire is too
severely damaged for the tire
sealant and compressor kit to be
effective. SeeRoadside Assistance
Program on page 12-6.
If the tire has a puncture less than a
14inch (6 mm) in the tread area
of the tire, seeTire Sealant
and Compressor Kit (V8 Engine) on
page 9-64.

Tire Sealant and
Compressor Kit
(V8 Engine)
This vehicle has a tire sealant and
compressor kit in place of a jack or
spare tire. It is located in a foam
container in the trunk. The tire
sealant and compressor kit can be
used to repair a at tire by sealing
small punctures in the tread of the
tire. It can also be used to inate an
underinated tire. The vehicle must
be driven for ve miles (8 kilometers)
after the tire is sealed and inated to
the recommended pressure to
ensure the sealant is distributed
evenly. For detailed instructions see
“Using the Tire Sealant and
Compressor Kit to Temporarily
Repair a Punctured Tire” later in this
section.The kit includes:
A. On/Off Switch
B. Air Compressor Accessory Plug
C. Air Compressor
D. Sealant Canister
E. Sealant/Air Hose
F. Air-only Hose
G. Pressure Gage
Tire Sealant
The sealant can temporarily seal a
small puncture up to 6 mm in
the tread area of the tire. The
sealant cannot seal sidewall
damage, large punctures, or a wheel
that has unseated from the wheel.
Read and follow the safe handling
instructions on the label adhered to
the sealant canister.
Check the tire sealant expiration
date on the sealant canister.
The sealant canister should be
replaced before its expiration date.
There is only enough sealant to
seal one tire. After usage, the
sealant canister and sealant/air hose
assembly must be replaced.
Replacement sealant canisters are
available from a dealer/retailer.
See “Removal and Installation of
Sealant Canister” later in this
section.
