Saab 2006 9-7X - Manual (Page 349)

Buying New Tires
The original equipment tires installed on your vehicle,
when it was new, were designed to meet the Tire
Performance Criteria Specification (TPC spec) system
rating. If you need replacement tires, Saab 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.
The 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. The 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 5-57 for additional
information.
{ CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes,
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, brands, or types may also cause damage
to your vehicle. Be sure to use the correct size,
brand, and type of tires on your vehicle’s
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.
