tire size PONTIAC G3 2009 User Guide

{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 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. SeeCompact Spare Tire on
page 5-78.
{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 your 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 5-58.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information Label. SeeLoading
the Vehicle on page 4-18, 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, 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 5-64andAccessories
and Modifications on page 5-3for 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. 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.

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 5-70for 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.
Tire Chains
Notice:Use tire chains only where legal and only
when you must. Use only SAE Class “S” type chains
that are the proper size for your 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 your 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 your vehicle.

Storing a Flat or Spare Tire and
Tools
{CAUTION:
Storing a jack, a tire, 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 all these
in the proper place.
To store a at or compact spare tire and tools:
1. Store the at tire or the compact spare in the
compact spare tire compartment.
2. Secure the retainer.
3. Store the tools securely in the foam tray and place
the tray back in the cargo area.
4. Replace the trim cover.
The compact spare tire is for temporary use only.
Replace the compact spare tire with a full-size tire
as soon as you can. SeeCompact Spare Tire on
page 5-78.
Compact Spare Tire
{CAUTION:
Driving with more than one compact spare tire at
a time could result in loss of braking and handling.
This could lead to a crash and you or others could
be injured. Use only one compact spare tire at
a time.
The compact spare tire was fully inated when the
vehicle was new, it can lose air after a time. Check the
ination pressure regularly. It should be 60 psi (414 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inated. The compact spare
is intended to perform well at speeds up to 50 mph
(80 km/h), so you can nish your trip and have your
full-size tire repaired or replaced where you want.
Replace your spare with a full-size tire as soon as
you can.
Notice:When the compact spare is installed, do not
take the vehicle through an automatic car wash with
guide rails. The compact spare can get caught on the
rails which can damage the tire, wheel and other
parts of the vehicle.
