Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, for
signs of wear or damage. See
When It Is Time for New Tires on
page 9-54for more information.
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). SeePart A:
Scheduled Maintenance
Services on page 11-3.
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.
SeeWhen It Is Time for NewTires on page 9-54andWheel
Replacement on page 9-59for
more information.
When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.
Tires should only be moved from
front to rear and rear to front on
the same side of the vehicle.
Do not include the compact
spare tire in the tire rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures to the amounts
shown on the Tire and
Loading Information label.SeeInflation - Tire Pressure on
page 9-47andLoading the
Vehicle on page 8-32.
{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 on page 9-62.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications
on page 10-2.

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 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
specic tires for the vehicle. If you
need replacement tires, GM strongly
recommends that you get tires that
are the same size, brand, load range,
speed rating, and construction type
(radial and bias-belted tires) as the
vehicle’s original tires. This way, the
vehicle will continue to have tires
that are designed to give the same
performance and vehicle safety,
during normal use, as the original
tires. SeeTire Sidewall Labeling on
page 9-42for additional information.
9-54 Vehicle Service and Care
2009 - Pontiac Vibe Owner Manual

GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires will
help keep the 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 the vehicle.
SeeTire Inspection and Rotation on
page 9-53.
{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
(Continued)
CAUTION (Continued)
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 9-70.
{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.
Vehicles that have a tire pressure
monitoring system could give
an inaccurate low-pressure warning
if tires not recommended for the
vehicle are installed. Tires that do
not match the original equipment
tires could give a low-pressure
warning that is higher or lower
than the proper warning level you
would get with original equipment
tires. SeeTire Pressure Monitor
System on page 9-48.
The vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label. See
Loading the Vehicle on page 8-32,
for more information about the
Tire and Loading Information label
and its location on the 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, antilock
brakes, traction control, and
electronic stability control, the
performance of these systems
can be affected.
{CAUTION
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 GM
specic wheel and tire systems
developed for your vehicle, and
have them properly installed by
a GM certied technician.
SeeBuying New Tires on page 9-54
andAccessories and Modifications
on page 9-3for additional
information.
Uniform Tire Quality
Grading
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum selection width.
For example:
Treadwear 200 Traction AA
Temperature A
The following information relates
to the system developed by the
Unites 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.
9-56 Vehicle Service and Care
2009 - Pontiac Vibe Owner Manual

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.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
12) 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.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 specied
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.
Vehicle Service and Care 9-57
2009 - Pontiac Vibe Owner Manual

Temperature — A, B, C
The temperature grades
are A (the highest), B, and C,
representing the tire’s resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled
conditions on a specied indoor
laboratory test wheel. Sustained
high temperature can cause the
material of the tire to degenerate
and reduce tire life, and
excessive temperature can
lead to sudden tire failure.
The grade C corresponds to
a level of performance which
all passenger car tires must
meet under the Federal MotorVehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the
laboratory test wheel than the
minimum required by law.
{WARNING
The temperature grade for this
tire is established for a tire
that is properly inated and
not overloaded. Excessive
speed, underination, or
excessive loading, either
separately or in combination,
can cause heat buildup and
possible tire failure.
Wheel Alignment and
Tire Balance
The tires and wheels on your vehicle
were aligned and balanced carefully
at the factory to give you the longest
tire life and best overall performance.
Adjustments to wheel alignment and
tire balancing will not be necessary
on a regular basis. However, if you
notice unusual tire wear or your
vehicle pulling to one side or the
other, the alignment might need to be
checked. If you notice your vehicle
vibrating when driving on a smooth
road, the tires and wheels might
need to be rebalanced. See your
dealer/retailer for proper diagnosis.

2009 - Pontiac Vibe Owner Manual

Wheel Replacement
Replace any wheel that is bent,
cracked or badly rusted or corroded.
If wheel nuts keep coming loose,
the wheel, wheel bolts and wheel
nuts should be replaced. If the
wheel leaks air, replace it (except
some aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer will know the
kind of wheel you need.
Each new wheel should have
the same load-carrying capacity,
diameter, width, offset and be
mounted the same way as the
one it replaces.If you need to replace any of the
wheels, wheel bolts or wheel
nuts, replace them only with new
GM original equipment parts.
This way, you will be sure to have
the right wheel, wheel bolts and
wheel nuts for the vehicle.
{CAUTION
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts on your vehicle can be
dangerous. It could affect the
braking and handling of your
vehicle, make your tires lose
air and make you lose control.
You could have a collision in
which you or others could be
injured. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.Notice:The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
SeeChanging a Flat Tire on
page 9-62for more information.Used Replacement Wheels
{CAUTION
Putting a used wheel on the
vehicle is dangerous. You cannot
know how it has been used
or how far it has been driven.
It could fail suddenly and cause
a crash. If you have to replace a
wheel, use a new GM original
equipment wheel.
Vehicle Service and Care 9-59
2009 - Pontiac Vibe Owner Manual

Tire Chains
{CAUTION
If the vehicle has P215/45R18
size tires, do not use tire chains.
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 the vehicle and
you or others may be injured in a
crash.
(Continued)
CAUTION (Continued)
Use another type of traction
device only if its manufacturer
recommends it for use on the
vehicle and tire size combination
and road conditions. Follow that
manufacturer’s instructions.
To help avoid damage to the
vehicle, drive slowly, readjust
or remove the device if it is
contacting the vehicle, and
do not spin the wheels.
If you do nd traction devices that
will t, install them on the front
tires.Notice:If the vehicle has a tire
size other than P215/45R18 size
tires, use tire chains only where
legal and only when you must.
Use only SAE Class “S” type
chains that are the proper size for
the tires. Install them on the front
tires and 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 the 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 the vehicle.
