Rotation Pattern for Non-GXP Tires Only
The correct rotation pattern shown here is only for
non-GXP tires.
Do not include the compact spare tire, if equipped,
in your vehicle's tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Tire and Loading Information label, and reset
the Tire Pressure Monitor System. See Tire
Pressure Monitor System on page 415 for
additional information.
Make certain that all wheel nuts are properly
tightened. See "Wheel Nut Torque" under
Capacities and Specifications on page 474.
CAUTION:
{
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. See Changing a Flat Tire on page 442.
