6. Visually inspect the tires to

make sure there are no nails or
other objects embedded that
could poke a hole in the tire
and cause an air leak.

7. Check the sidewalls to make

sure there are no gouges, cuts
or bulges.

Note:

If you are checking tire

pressure when the tire is hot, for
example you have driven more than
1.0 mi (1.6 km), never bleed or
reduce tire pressure. The tires are
hot from driving and it is normal for
pressures to increase above
recommended cold pressures. A
hot tire at or below recommended
cold inflation pressure could be
significantly under-inflated.

Note:

If you have to drive a

distance to get air for the tires,
check and record the tire pressure
first and add the appropriate air
pressure when you get to the
pump. It is normal for tires to heat
up and the tire pressure to increase
as you drive.

Note:

If you over inflate the tire,

release air by pressing on the metal
stem in the center of the valve.
Then recheck the pressure with
your tire gauge.

Note:

Some spare tires operate at

a higher inflation pressure than the
other tires. For T-type mini-spare
tires, refer to the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at 60 psi (4.15 bar).
For full-size and dissimilar spare
tires, refer to the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at the higher of the
front and rear inflation pressure as
shown on the Tire Label.

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.
