Your vehicle’s original equipment tires are listed on the
Tire and Loading Information label. See Loading
Your Vehicle on page 4-26, for more information about
the Tire and Loading Information label and its location
on your vehicle.
Vehicles that have performance tires P235/50R17 95V
(front axle) and P255/45R17 98V (rear axle) are mounted
on wheels with different rim widths. The front axle tires
are mounted on rims 7.5 inches (19.05 cm) wide and
the rear axle tires require wheels with a minimum rim
width of 8 inches (20.32 cm). The original equipment
wheels designed for P255/45R17 98V size tires are
etched with the words REAR ONLY. When replacing
P255/45R17 98V size tires have them mounted on
wheels with a minimum width of 8 inches (20.32 cm) and
marked REAR ONLY. See Wheel Replacement on
page 5-80.
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, anti-lock 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.
