If your tires have too much air (overinflation),
you
can get the following:
0 Unusual wear
0 Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or n101-e. Also. check the
tire pressure
of the spare tire.
I! you have a compact spare tire. it should be at 60 psi
(420
k 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 thcm. Radial tires may look
properly inflated even when they're underintlatecl.
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 s11o111d be rotated every 6,000 to 8,000 miles
( IO 000 to 13 000 km). Any time you notice unusual
we;^. rotate your tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See "When 1t.s Time for New Tires" and
"Wheel Replacement" later
in this section for
more information.
Thc purpose
of' reg~~lar rotation is to achieve more
uniform wear
fur all tires on the vehicle. The first
rotation
is thu most important. See "Schecluled
Maintenance Services"
in the Index for scheduled
rotation intervals.

If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificatioflire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque’’ in
the Index.
Rust or dirt on a wheel, or on 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
“Changing a Flat Tire” in the Index.)

Mixing tires could cause you to lose control 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
(if you have one). It was developed for
use on
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 limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary
with respect to these
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
c Urades, they rnust also conform to Federal safety
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 government course as a tire
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 clilnate.
