Buying New Tires GM has developed and matched specific tires for your vehicle. The original equipment tires installed on your vehicle, when it was new, were designed to meet General Motors Tire Performance Criteria Specification (TPC Spec) system rating. If you need replacement tires, GM strongly recommends that you get tires with the same TPC Spec rating. This way, your vehicle will continue to have tires that are designed to give the same performance and vehicle safety, during normal use, as the original tires. GM's exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of your 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 an MS for mud and snow. See Tire Sidewall Labeling on page 5-63 for additional information. GM recommends replacing tires in sets of four. This is because uniform tread depth on all tires will help keep your vehicle performing most like it did when the tires were new. Replacing less than a full set of tires can affect the braking and handling performance of your vehicle. See Tire Inspection and Rotation on page 5-75 for information on proper tire rotation. {CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes (other than those originally installed on your vehicle), brands, or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes (other than those originally installed on your vehicle) may also cause damage to your vehicle. Be sure to use the correct size, brand, and type tires on all wheels. If your vehicle has a compact spare tire, it is all right to drive your vehicle with the compact spare temporarily. It was developed for use on your vehicle.

Buying New Tires

GM has developed and matched speciﬁc tires for

your vehicle. The original equipment tires installed

on your vehicle, when it was new, were designed to

meet General Motors Tire Performance Criteria

Speciﬁcation (TPC Spec) system rating. If you need

replacement tires, GM strongly recommends that

you get tires with the same TPC Spec rating. This

way, your vehicle will continue to have tires that are

designed to give the same performance and vehicle

safety, during normal use, as the original tires.

GM’s exclusive TPC Spec system considers over

a dozen critical speciﬁcations that impact the

overall performance of your 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 an MS for mud and snow. See

Tire

Sidewall Labeling on page 5-63

for additional

information.

GM recommends replacing tires in sets of four.

This is because uniform tread depth on all tires will

help keep your vehicle performing most like it did

when the tires were new. Replacing less than a full

set of tires can affect the braking and handling

performance of your vehicle. See

Tire Inspection

CAUTION:

Mixing tires could cause you to lose

control while driving. If you mix tires of

different sizes (other than those originally

installed on your vehicle), brands, or types

(radial and bias-belted tires), the vehicle

may not handle properly, and you could

have a crash. Using tires of different sizes

(other than those originally installed on

your vehicle) may also cause damage to

your vehicle. Be sure to use the correct

size, brand, and type tires on all wheels.

If your vehicle has a compact spare tire, it

is all right to drive your vehicle with the

compact spare temporarily. It was
