holes in the inner and outer wheels on each side
are lined up.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Tire and Loading Information label. See Loading
Your Vehicle on page 409.
Make certain that all wheel nuts are properly
tightened. See "Wheel Nut Torque" under
Capacities and Specifications on page 609.
