GM has developed and matched specific tires for the vehicle. The original equipment tires installed were designed to meet General Motors Tire Performance Criteria Specification (TPC Spec) system rating. When replacement tires are needed, GM strongly recommends buying tires with the same TPC Spec rating.
GM's exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of the vehicle, including brake system performance, ride and handling, traction control, and tire pressure monitoring performance. GM's TPC Spec number is molded onto the tire's sidewall near the tire size. If the tires have an all-season tread design, the TPC Spec number will be followed by MS for mud and snow.
GM recommends replacing worn tires in complete sets of four.
Uniform tread depth on all tires will help to maintain the performance of the vehicle.
Braking and handling performance may be adversely affected if all the tires are not replaced at the same time.
If proper rotation and maintenance have been done, all four tires should wear out at about the same time.
However, if it is necessary to replace only one axle set of worn tires, place the new tires on the rear axle.
Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y and ZR speed rated tires. Never exceed the winter tire's maximum speed capability when using winter tires with a lower speed rating.
WARNING
Tires could explode during improper service. Attempting to mount or dismount a tire could cause injury or death.
Only your dealer or authorized tire service center should mount or dismount the tires.
WARNING
Mixing tires of different sizes, brands, or types may cause loss of control of the vehicle, resulting in a crash or other vehicle damage. Use the correct size, brand, and type of tires on all wheels.
WARNING
Using bias-ply tires on the vehicle may cause the wheel rim flanges to develop cracks after many miles of driving.
A tire and/or wheel could fail suddenly and cause a crash.
Use only radial-ply tires with the wheels on the vehicle.
If the vehicle tires must be replaced with a tire that does not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction (radial) as the original tires.
Vehicles that have a tire pressure monitoring system could give an inaccurate low-pressure warning if non-TPC Spec rated tires are installed.
The Tire and Loading Information label indicates the original equipment tires on the vehicle.
