Different Size Tires And Wheels; Uniform Tire Quality; Grading - Cadillac CTS 2011 Owner's Manual

Vehicles that have a tire pressure
monitoring system could give an
inaccurate low pressure warning if
non TPC Spec rated tires are
installed on it. Non TPC Spec rated
tires may give a low pressure
warning that is higher or lower than
the proper warning level you would
get with TPC Spec rated tires. See
Tire Pressure Monitor Operation on
page 10 77.
Your vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9 11,
for more information about the Tire
and Loading Information label and
its location on your vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires, this
could affect the way your vehicle
performs, including its braking, ride
and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as anti lock
brakes, traction control, and
electronic stability control, the
performance of these systems can
be affected.

page 10 83 and Accessories and
