Vehicle Care 9-75
The vehicle needs new tires 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.
The rubber in tires degrades over
time. This is also true for the spare
tire, if the vehicle has one, even
if it is not being used. Multiple
conditions affect how fast this aging
takes place, including temperatures,
loading conditions, and inflation
pressure maintenance. With proper
care and maintenance tires typically
wear out before they degrade due to
age. If you are unsure about the
need to replace the tires as they get
older, consult the tire manufacturer
for more information.
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.
