2003 PONTIAC GRAND PRIX wheel size

The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or
location of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service
on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).
If you ever replace your tires with those not having
a
TPC Spec number, make sure they are the same
size, load range, speed rating and construction type
(bias, bias-belted or radial) as your original tires.

while driving. If you mix tires of different sizes
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you could have a crash. Using tires of different
sizes may
also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels.
It’s all right to drive with your
compact spare temporarily,
it was developed
for use on your vehicle. See “Compact Spare
Tire”
in the index.

Tire Chains
If your vehicle is an SE model with P225/60R16
size tires, don’t use tire chains, there’s 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 your 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 your
vehicle and tire size combination and road
conditions.
Follow that manufacturer’s
CAUTION: (Continued) instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if
it’s contacting your vehicle, and don’t
spin your wheels.
If you do find traction devices that will fit,
install them on the front tires.
Notice; If your vehicle is a GT model, a GTP model,
or if you have an
SE model without P225/60R16
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 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.

10. Don’t try to put the wheel cover on your compact
spare tire. It won’t fit. Store the wheel cover in the
trunk until you have the flat tire repaired or
replaced.
Notice: Wheei covers won’t fit on your compact
spare.
If you try to put a wheel cover on your
compact spare, you could damage the cover or
the spare.
Storing the Flat Tire and Tools
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.
After you’ve put the compact spare tire on your vehicle,
you’ll need to store the flat tire in the trunk. Use the
following procedure to secure the flat tire in the trunk. When
storing a full-size tire, you must use the extension
to help avoid wheel surface damage. Use the extension
and protector/guide located in the foam holder.
To store a
full-size tire, place the tire in the trunk valve stem facing
down, with the protector/guide placed through a wheel
bolt hole. Remove the protector and attach the retainer
securely. When putting the compact spare back in the
trunk, place the protector/guide back
in the foam holder.
Store the cover as far forward as possible.

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time.
Check the inflatior! pressure regularly.
!t should be
60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact spare
is made to perform well at speeds up to
65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size
tire repaired or replaced where you want.
Of course,
it’s best to replace your spare with a full-size tire as soon
as you can. Your spare will last longer and be in good
shape in case you need
it again.
Notice: When the compact spare is installed, don’t
take your vehicle through an automatic car wash
with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare tire
and its wheel together.
Notice: Tire chains won’t fit your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don’t use tire chains on
your compact spare.
