1997 PONTIAC FIREBIRD spare wheel

When to Check
Check your tires once a month or more.
uon’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may
look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s
Time for New Tires” and
“Wheel Replacement’’ later in this section for
more information. The
purpose
of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.
If you don’t have P245/5OZR16 or P275/40ZR17
Goodyear Eagle GS-C tires, use the rotation pattern
shown above for your tires.

If you have P245/50ZRl6 or P27940ZR17 Goodyear
Eagle
GS-C tires, they must roll in a certain direction
for the best overall performance. The direction is shown
by an arrow on the sidewall. Because these tires are
directional, they should be rotated
as shown here. These
tires should
only be moved from front to rear and rear to
front on the same side of the vehicle.
Don’t include the compact spare tire in your tire
rotation.
After the tires
have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make
certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque” in
the Index.
I
Rust or dirt on a wheel, or on the pa; cJ to which
it is fastened, can make wheel nuts become loose
after a time.
The wheel could come off and caus’e
an accident.
When you change a wheel, remove
any rust or dirt frolm 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 you
need to,
to get all the rust or dirt off. (See
“Changing a Flat Tire” in the Index.)

Mixing tires could cause you to lose control while
driving.
If you mix tires of dif€erent sizes or types
(radi,al
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,
though. It was developed for use 0n your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, 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 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 lirnited-pro'duction 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 specified government test course. For
example, a tire graded 150 would wear one and a half
(1 1/2) times as well on the gov'esnrnent 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.
