Inspecting the Tires and Wheel
Valve Stems
Periodically inspect the tire treads
for uneven or excessive wear and
remove objects, for example
stones, nails or glass that may be
wedged in the tread grooves.
Check the tire and valve stems for
holes, cracks, or cuts that may
permit air leakage and repair or
replace the tire and replace the
valve stem. Inspect the tire
sidewalls for cracking, cuts,
bruises and other signs of damage
or excessive wear. If internal
damage to the tire is suspected,
have the tire removed and
inspected in case it needs to be
repaired or replaced. For your
safety, tires that are damaged or
show signs of excessive wear
should not be used because they
are more likely to blow out or fail.
Incorrect or inadequate vehicle
maintenance can cause tires to
wear abnormally. Inspect all the
tires, including the spare,
frequently, and replace them if
one or more of the following
conditions exist:

Tire Wear
E142546
When the tread is worn down to
0.08 in (2 mm), tires must be
replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or wear bars, which
look like narrow strips of smooth
rubber across the tread will
appear on the tire when the tread
is worn down to 0.08 in (2 mm).
When the tire tread wears down
to the same height as these wear
bars, the tire is worn out and must
be replaced.
Tire Damage
Periodically inspect the tire treads
and sidewalls for damage, for
example bulges in the tread or
sidewalls, cracks in the tread
groove or separation in the tread
or sidewall. If damage is observed
or suspected have the tire
inspected by a tire professional.
Tires can be damaged during
off-road use, so inspection after
off-road use is also
recommended.
