Different Size Tires And Wheels - GMC 2008 Envoy Denali Owner's Manual

Vehicles equipped with a tire pressure monitoring
system may give an inaccurate low-pressure
warning if non-TPC spec rated tires are installed
on your 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 Tire Pressure Monitor
System on page 5-67.
Your vehicle's original equipment tires are listed
on the Tire and Loading Information Label. See
Loading Your Vehicle on page 4-34, 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, rollover
airbags, traction control, and electronic stability control,
the performance of these systems can be affected.

CAUTION:
{
If you add different sized wheels, your vehicle
may not provide an acceptable level of
performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will
crash and suffer serious injury. Only use GM
specific wheel and tire systems developed for
your vehicle, and have them properly installed
by a GM certified technician.
