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 at the
intervals specified in the
Maintenance Schedule. See
Maintenance Schedule 0 310.
Tires are rotated to achieve a
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.
