The purpose of regular rotation is to achieve more
uniform wear for all tires
on the
vehicle. The first
rotation is the most important. See "Scheduled
Maintenance Services" in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating your tires, always use the correct
rotation pattern shown here.
Don't include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel nuts
are properly tightened. See "Wheel Nut Torque" in
the Index.
I
A
CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel
nuts
become loose
after a 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 you
need to, to get all the rust or dirt off. (See
"Changing a Flat Tire" in the Index.)
