Buying New Tires - Cadillac XLR-V 2006 Owner's Manual

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 an MS for mud
and snow. See Tire Sidewall Labeling on page 6-52 for
additional information.
Winter tires with the same speed rating as your original
equipment tires may not be available for H, V, W, Y,
and ZR speed rated tires. If you choose snow tires with
a lower speed rating, never exceed the tire's maximum
speed capability.

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), brands or
types, may also cause damage to your vehicle.
Be sure to use the correct size, brand, and
type tires on all four wheels.
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.
