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 Scheduled Maintenance 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.
