Different Size Tires And Wheels - Hummer 2006 H3 Owner's Manual

If you must replace your vehicle's tires with those that
do not have a TPC Spec number, make sure they
are the same size, load range, speed rating, and
construction type (radial and bias-belted tires) as your
vehicle's original tires.
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 5-61.
Your vehicle's original equipment tires are listed on
the Tire and Loading Information Label. This label
is attached to the vehicle's center pillar (B-pillar).
See Loading Your Vehicle on page 4-52, for more
information about the Tire and Loading Information
Label.

Different Size Tires and Wheels

If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
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, antilock brakes; 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.
See Buying New Tires on page 5-66 and Accessories
and Modifications on page 5-3 for additional information.
