firmly into the notch in the vehicle’s frame nearest
the flat tire. Put the compact spare tire near you.

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
(42Q Wa).
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 perfonnwell at posted speed limits for
distances up to.3,OOO miles
(5 000 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.
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.
Don’t use your compact spare on other vehicles.
And don’t
mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
i
NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
,the chains too. Don’t use tire chains on’-your
compact spare.

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 four wheels.
It's all right to drive with your compact spare,
though. 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 temporqy 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
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 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.
