2010 PONTIAC VIBE Owners 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 on page 9-54 andTire
Rotation on page 9-55 .
{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
(Continued)
CAUTION (Continued)
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 9-68.
{CAUTION
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.
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.
See Tire Pressure Monitor System
on page 9-50.
The vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label. See
Vehicle Load Limits on page 8-12 ,
for more information about the Tire
and Loading Information label and
its location on the vehicle.
Vehicle Care 9-57

Different Size Tires and
Wheels
If you add wheels or tires that are
a different size than your original
equipment wheels and tires, this
could 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, traction control, and
electronic stability control, the
performance of these systems
can be affected.
SeeBuying New Tires on page 9-56
and Accessories and Modications
on page 9-3 for additional
information.
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.
9-58 Vehicle Care

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.
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 specified indoor
laboratory test wheel. Sustained
high temperature can cause thematerial 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 Motor Vehicle
Safety Standard No. 109.
Grades B and A represent
higher levels of performance
on the laboratory test wheel than
the minimum required by law.
It should be noted that the
temperature grade for this tire
is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
Vehicle Care 9-59

Wheel Alignment and
Tire Balance
The tires and wheels on the vehicle
were aligned and balanced carefully
at the factory to give 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 there
is unusual tire wear or the vehicle
pulls to one side or the other, the
alignment should be checked. If the
vehicle vibrates when driving on a
smooth road, the tires and wheels
might need to be rebalanced.
See your dealer/retailer for proper
diagnosis.
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.
See If a Tire Goes Flat on page 9-62
for more information.
9-60 Vehicle Care

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.
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(Continued)
CAUTION (Continued)
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.
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 find traction devices that
will fit, 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.
Vehicle Care 9-61

If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially if
you maintain your vehicle’s tires
properly. If air goes out of a tire,
it is much more likely to leak out
slowly. But if you should ever have
a blowout, here are a few tips about
what to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop well out of
the traffic lane.
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 bevery bumpy and noisy, but you can
still steer. Gently brake to a stop,
well off the road if possible.
{CAUTION
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
is designed only for changing a
flat tire. If it is used for anything
else, you or others could be badly
injured or killed if the vehicle slips
off the jack. If a jack is provided
with the vehicle, only use it for
changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. See Hazard
Warning Flashers on page 5-3 .
{CAUTION
Changing a tire can be dangerous.
The vehicle can slip off the jack
and roll over or fall on you or other
people. You and they could be
badly injured or even killed. Find
a level place to change your tire.
To help prevent the vehicle from
moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift lever in
P (Park), or shift a manual
transmission to 1 (First) or
R (Reverse).
3. Turn off the engine and do not restart while the vehicle
is raised.
4. Do not allow passengers to remain in the vehicle.
(Continued)
9-62 Vehicle Care

CAUTION (Continued)
To be certain the vehicle will not
move, put blocks at the front and
rear of the tire farthest away from
the one being changed. That
would be the tire on the other
side, at the opposite end of the
vehicle.
When the vehicle has a flat tire (B),
use the following example as a
guide to assist you in the placement
of wheel blocks (A).
