CAUTION:

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.

CAUTION:

If you use bias-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 Tire Quality Grading

Quality grades can be found where applicable on the tire

sidewall between tread shoulder and maximum section

width. For example:

Treadwear 200 Traction AA Temperature A

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.
