A CAUTION:
Rust or dirt on the wheel, or on rne 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.
Remove any rust or dirt from the wheel bolts, mounting
surfaces
or spare wheel. Place the spare on the wheel
mounting surface.

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 p-per place.

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 kPa). The compact spare is made to go up to 3,000
miles (5000 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.
Your anti-lock brake system warning light may come
on
when you are driving with a compact spare. See
"Anti-Lock Brake System Warning Light"
in the Index.
NOTICE:
' Don't take your compact spare through an
automatic car wash with guide rails. The
compact spare can get caught
on the rails. Tha
can damage the tire and wheel, and maybe other
parts of your vehicle.

Don't use your compact spare on some other vehicle.
And don't mix your compact spare or wheel with other
wheels
or tires. They won't fit. Keep your spare and its
wheel together.
Tire chains won't fit your compact spare. Using
them will damage your vehicle and destroy the
chains too. Don't use tire chains on your

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 kPa).
How to Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking 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 “Scheduled Maintenance
Services”
in the Index.
I
I‘
Use this rotation pattern.
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 “Wheel Nut Torque”
in the
Index.

When It’s Time for New Tires
b One wav to tell when it’s r’
time for new tires is to

indicators, which will
appear when your tires
have only
2/32 inch (1.6
mm) or less of tread
remaining.

1/2) times as well on the government 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.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B,
and C. They represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on
specified government test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire
is based
on braking (straight-ahead) traction tests and does not
include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade
C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire
is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or
in combination,
can cause heat buildup and possible tire failure.
These grades are molded
on the sidewalls of passenger
car tires.
While the tires available
as standard or optional
equipment
on General Motors vehicles may vary with
respect to these grades, all such tires meet General
Motors performance standards and have been approved
for use on General Motors vehicles. All passenger type
(P Metric) tires must conform to Federal safety
requirements
in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give
you the longest tire life
and best overall performance.
