Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon
as possible and check
wheel alignment. Also crheck for damaged tires or
wheels.
See “When It’s ‘Time for New Tires”
and “Wheel Replacement” later in this section for
more information.
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 Index for scheduled
rotation intervals.
1
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
CertificatiodTire label. Make certain that all wheel
nuts are properly tightened. See “Wheel Nut Torque”
in the Index.
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.)
