Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000
k m )
for any signs of unusual w e a r .
If unusual wear is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See "When It's Time for New
Tires" and "Wheel Replacement" later in this section for
more information.
When rotating your tires, always use the correct rotation
pattern shown here.
Don't include the compact.spa.re 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
The purpose of regular rotation is to achieve more
uniforrn wear for all tires on
the vehicle. The first
rotation is the most important. See "Scheduled
Maintenance Services"
in the
Index for scheduled
rotation
intervals.

Rust or dirt on
a
wheel, l r on the part
D
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.)
