To make your tires last longer, have them inspected and rotated a\
t the
mileages recommended in the Maintenance Schedule. See “Scheduled
Maintenance Services” in the Index.
Use this rotation pattern.
If your vehicle has front tires with different load ratings or tread designs (such
as all season vs. on/off road) than the rear tires, don’t \
rotate your tires front
to rear.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the CertificationRire label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.
CAUTION I
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 an\
y

an emergency, you can use a cloth or 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.)

6,000 miles (1 0 000
kilometers) for Schedule I or 7,500 miles (12 500 kilometers) for
Schedule
II and then every 7,500 miles (12 500 kilometers) thereafter.

wear and rotors for surface condition.
Also inspect drum brake linings for
wear and cracks. Inspect other brake parts, including drums, wh\
