FORD 2013 F-150 v.3 - Manual (Page 375)

Maximum Inflation Pressure is the tire manufacturer’s maximum
permissible pressure or the pressure at which the maximum load can be
carried by the tire. This pressure is normally higher than the manufacturer’s
recommended cold inflation pressure, which can be found on the Safety
Compliance Certification Label (affixed to either the door hinge pillar,
door-latch post, or the door edge that meets the door-latch post, next to
the driver’s seating position), or Tire Label which is located on the B-Pillar
or the edge of the driver’s door. The cold inflation pressure should never
be set lower than the recommended pressure on the Safety Compliance
Certification Label or Tire Label.
When weather temperature changes occur, tire inflation pressures also
change. A 10°F (6°C) temperature drop can cause a corresponding
drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures
frequently and adjust them to the proper pressure which can be found
on the Safety Compliance Certification Label or Tire Label.
To check the pressure in your tire(s):
1. Make sure the tires are cool, meaning they are not hot from driving
even a mile.
Note: If you are checking tire pressure when the tire is hot (for
example, driven more than 1 mile [1.6 kilometers]), never bleed or
reduce air 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 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.
