Owner's Manual

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,
though.
It was developed for use on your vehicle.
If you use bic 'ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles
of driving. A tire and/or wheel could
fail suddenly, causing
a crash. Use only radial-ply
tires with the wheels
on your vehicle.
Uniform '--I 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
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
