Note: If you have to drive a
distance to get air for your tire(s),
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 air pressure inside to go
up as you drive.
2. Remove the cap from the valve
on one tire, then firmly press the
tire gauge onto the valve and
measure the pressure.
3. Add enough air to reach the
recommended air pressure.
Note: If you overfill the tire, release
air by pressing on the metal stem
in the center of the valve. Then
recheck the pressure with your tire
gauge.
4. Replace the valve cap.
5. Repeat this procedure for each
tire, including the spare.
Note: Some spare tires operate at
a higher inflation pressure than the
other tires. For T type mini-spare
tires, (see 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, see 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
Safety Compliance Certification
Label or Tire Label.

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.
Tire Inflation Information
improperly used, serviced or
maintained. To reduce the risk of
serious injury, never attempt to
re-inflate a tire which has been run
flat or seriously under-inflated
without first removing the tire
from the wheel assembly for
inspection. Do not attempt to add
air to tires or replace tires or
wheels without first taking
precautions to protect persons
and property.
All tires with Steel Carcass Plies
(if equipped):
This type of tire utilizes steel cords
in the sidewalls. As such, they
cannot be treated like normal light
truck tires. Tire service, including
adjusting tire pressure, must be
performed by personnel trained,
supervised and equipped
according to Federal Occupational
Safety and Health Administration
regulations. For example, during
