1993 PONTIAC GRAND-PRIX inflation pressure

Compact Spare Tire
Although the compact spare 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 1tPa). The compact spare is
made to go up to 3,000 miles (5 000 lm),
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. Your anti-lock brake
system warning light may come on
when
you are driving with a compact
spare. See the
Index under Anti-Lock
Brake System Warning Light.

Loading Your Vehicle
Two labels on your vehicle show how
much weight it may properly carry. The
Tire-Loading Information label found
on the inside of the trunk lid tells you
the proper size, speed rating and
recommended inflation pressures for
the tires on your vehicle. It also gives
you important information about the
number of people that can be in your
vehicle and the total weight that you
can carry. This weight is called the
Vehicle Capacity Weight and includes
the weight of all occupants, cargo, and
all nonfactory-installed options.
The other label is the Certification label,
found on the rear edge of the driver’s
door. It tells you the gross weight
capacity of your vehicle, called the GVWR
(Gross Vehicle Weight Rating).
The GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your
vehicle, or the Gross Axle Weight
Rating (GAWR) for either the front or
rear axle.
And,
if you do have a heavy load, you
should spread it out. Don’t carry more
than
167 lbs. (75 kg) in your trunk.

Inflation-Tire Pressure
The Tire-Loading Information label
which is on the inside of the trunk lid
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 a mile. Don’t let anyone
tell you th

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 ItPa).
How to Check:
Use a good quality pocket-type gage to
check tire pressure. Simply loolting at
the tires will not tell you the pressure,
especially if you have radial tires-
which may
look properly inflated even if
they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt
and moisture.

Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See the
Index
under Scheduled Maintenance
Services.
Use this rotation pattern.
If you don't have P245/50ZR16 size
tires, use the rotation pattern shown
above for your size tires.
256
If you have P245/510ZR16 size tires,
they must roll
in a certain 'direction for
the best overall performance. The
direction is shown
by an arrow on both
sidewalls. Because these tirles are
directional, they should be rotated
as
shown in the example above. These
tires should only be moved
from front
to rear and rear to front
on the same
side
of the vehicle.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown
on the Tire-Loading Information
label. Make certain that
all wheel nuts
are properly tightened. See the Index
under Wheel Nut Torque.
Rust or dirt on a wheel, or on
ri the parts to which it is
fastened, can make 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
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
the
Index under Changing a Flat
Tire.)
