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.
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. See
When It Is Time for New Tires
on page 10 60 and Wheel
Replacement on page 10 64.
