spare wheel PONTIAC FIREBIRD 1997 User Guide

Mixing tires could cause you to lose control while
driving.
If you mix tires of dif€erent sizes or types
(radi,al
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 0n 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 lirnited-pro'duction 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 gov'esnrnent 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.
