*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.
