When It Is Time for New Tires

One way to tell when it is

time for new tires is to

check the treadwear

indicators, which will

appear when your tires

have only 1/16 inch

(1.6 mm) or less of tread

remaining. Some

commercial truck tires

may not have treadwear

indicators.

You need a new tire if any of the following

statements are true:

• You can see the indicators at three or more

places around the tire.

• You can see cord or fabric showing through

the tire’s rubber.

• The tread or sidewall is cracked, cut or

snagged deep enough to show cord or fabric.

• The tire has a bump, bulge, or split.

• The tire has a puncture, cut, or other damage

that cannot be repaired well because of the size

or location of the damage.

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 by the tire manufacturer.

If the tires have an all-season tread design,

the TPC spec number will be followed by a MS,

for mud and snow. See Tire Sidewall Labeling

on page 445 for additional information.
