Buick 2011 Regal Owner's Manual page 315

Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low pressure warning if non TPC
Spec rated tires are installed on
the vehicle. 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
.
The vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
for more information
about the Tire and Loading
Information label and its location
on the vehicle.
If you add wheels or tires that are a
different size than the original
equipment wheels and tires, this
could affect the way the vehicle
performs, including its braking, ride
and handling characteristics,
stability, and resistance to rollover.
Additionally, if the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.
