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 according to the
interval specified in the Maintenance
Schedule. See
Tires are rotated to achieve a more
uniform wear for all tires. The first
rotation is the most important.
Anytime unusual wear is noticed, rotate
the tires as soon as possible, check for
proper tire inflation pressure, and check
for damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel alignment.
