Buying New Tires - Chevrolet 2005 SSR Pickup Owner's Manual

Buying New Tires

To find out what kind and size of tires your vehicle
needs, look at the Certification/Tire label or the Tire and
Loading Information label. See Loading Your Vehicle
on page 4-29, for examples of these labels and
where they are located on your vehicle.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire's sidewall. When you get new
tires, GM recommends that you get tires with that same
TPC Spec number. That way your vehicle will continue
to have tires that are designed to give proper endurance,
handling, load range, speed rating, traction, ride and
other characteristics during normal service on your
vehicle. If your tires have an all-season tread design,
the TPC number will be followed by an "MS" (for
mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
Winter tires with the same speed rating as your
original equipment tires may not be available for H, V,
W 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) 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 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.
