Tire Inspection

We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
The indicators at three or
more places around the tire
can be seen.
There is cord or fabric
showing through the tire's
rubber.
The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
Vehicle Care
The tire has a bump, bulge,
or split.
The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.

Tire Rotation

Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule on
page 11 3.
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Any time unusual wear is
noticed, rotate the tires as
soon as possible and check
the wheel alignment. Also check
for damaged tires or wheels.
