FORD 2014 F-150 Raptor v.3 - Manual (Page 273)

*Standard load: A class of
P-metric or Metric tires designed
to carry a maximum load at set
pressure. For example: For
P-Metric tires 35 psi (2.4 bar) or
36 psi (2.5 bar) depending on tire
size and for Metric 36 psi (2.5 bar).
Increasing the inflation pressure
beyond this pressure will not
increase the tire’s load carrying
capability.
*Extra load: A class of P-metric
or Metric tires designed to carry a
heavier maximum load at 42 psi
(2.9 bar). Increasing the inflation
pressure beyond this pressure will
not increase the tire’s load
carrying capability.
*kPa: Kilopascal, a metric unit of
air pressure.
*PSI: Pounds per square inch, a
standard unit of air pressure.
*Cold tire pressure: The tire
pressure when the vehicle has
been stationary and out of direct
sunlight for an hour or more and
prior to the vehicle being driven for
1 mile (1.6 kilometers).
*Recommended inflation
pressure: The cold inflation
pressure 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 located on
the B-pillar or the edge of the
driver's door.
B-pillar: The structural member
at the side of the vehicle behind
the front door.
*Bead area of the tire: Area of
the tire next to the rim.
* Sidewall of the tire: Area
between the bead area and the
tread.
*Tread area of the tire: Area of
the perimeter of the tire that
contacts the road when mounted
on the vehicle.
*Rim: The metal support (wheel)
for a tire or a tire and tube
assembly upon which the tire
beads are seated.
Information Contained on the
Tire Sidewall
Both United States and Canada
Federal regulations require tire
manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and
describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire
Identification Number for safety
standard certification and in case
of a recall.
