Different Size Tires and Wheels
If wheels or tires are added that are a different
size than the 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.
{
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 the specific wheel and
tire systems developed for your vehicle,
and have them properly installed.
See Accessories and Modifications on page 191
