1998 PONTIAC FIREBIRD flat tire

Position the jack under the vehicle. There is a notch in
the vehicle’s rocker flange on the coupe model. Raise
the jack head until
it fits firmly into the notch nearest the
flat tire.
On convertible models, place the jack in a similar location.

3. Raise the vehicle by rotating the wheel wrench to
the right (clockwise). Raise the vehicle far enough
off the ground so there is enough room for the spare
tire
to fit. Remove all the wheel nuts and take off
the flat tire.
4. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and
spare wheel.
A CAUTION:
Rust or dirt on the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after
a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the 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.

NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
Don’t try to put
a center cap on your compact spare
tire. It won’t fit. Store the center cap in the rear area
until
you have the flat tire repaired or replaced.
I NOTICE:
Center caps won’t fit on your compact spare. If
you try to put a center cap on your compact
spare, you could damage the cover or the spare.
Storing a Flat or Spare Tire and Tools
A 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.

Replace the jack, wheel wrench and flat tire using the
storage instructions. When
you replace the trim panel,
be sure to tuck it under the weatherstrip.

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 inflation pressure regularly. It 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
perfom well at speeds up
to 65 mph (105 km/h) for
distances
up to 3,000 miles (5 OOO km), so you can finish
your trip and have your full-size tire repaired or replaced
where you want. (When the compact spare is used on the
rear axle, see Notice following.) 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:
If the compact spare is used as a rear tire, do not
drive faster than
50 mph (80 M). Damage to
the rear axle may occur if the compact spare is
driven faster than
50 mph (80 km/h).
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.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about
your tire wmanty and where to obtain service, see
your Pontiac Warranty booklet for details.
I A CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause
overheating as a result
of too much friction.
You could have an air-out
and a serious
accident. See “Loading
Your Vehicle” in
the Index.
Underinflated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued) CAUTION:
(Continued)
I
Overinflated tires are mo
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or
if your tires have
been damaged, replace them.
See “Inflation
-- Tire Pressure” in this section
for inflation pressure adjustment for higher
speed driving.

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
driver’s door, shows the correct inflation pressures
for
your tires when they’re cold. “Cold” means your vehicle\
has been sitting for at least three hours
or driven no
more than
I mile (1.6 km).
If you’ll be driving at high speeds (e.g., speeds of
100 mph (160 km/h or higher), where it is legal, set
the cold inflation pressure to the maximum inflation
pressure shown on the tire sidewall, or to
38 psi
(265 Wa), whichever is lower. See the example below.
When you end this high-speed driving, return to the cold inflation pressures shown on the Tire-Loading
Information label.
Example: You’ll find maximum load and inflation pressure
molded on the tire’s sidewall, in small letters, near the
rim flange. It will read something like this: Maximum
load
690 kg (1521 lbs.) 0 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high-speed driving at
38 psi (265 Wa).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right.
It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
0 Bad handling
0 Rough ride
0 Needless damage from road hazards.

When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be
at
60 psi (420 Pa).
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.
