I030D01JM-AATTIRE TERMINOLOGY AND DEFINI-
TIONS
Air Pressure: The amount of air inside
the tire pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight: This means the
combined weight of optional accesso-
ries. Some examples of optional ac-
cessories are, automatic transmission,
power seats, and air conditioning.
Aspect Ratio: The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords that
is located between the plies and the
tread. Cords may be made from steel or
other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that hold
the tire onto the rim.
Bias Ply Tire: A pneumatic tire in which
the plies are laid at alternate angles
less than 90 degrees to the centerline of
the tread.Cold Tire Pressure: The amount of air
pressure in a tire, measured in pounds
per square inch (psi) or kilopascals
(kPa) before a tire has built up heat from
driving.
Curb Weight: This means the weight of
a motor vehicle with standard and op-
tional equipment including the maxi-
mum capacity of fuel, oil and coolant,
but without passengers and cargo.
DOT Markings: A code molded into the
sidewall of a tire signifying that the tire
is in compliance with the U.S. Depart-
ment of Transportation motor vehicle
safety standards. The DOT code in-
cludes the Tire Identification Number
(TIN), an alphanumeric designator which
can also identify the tire manufacturer,
production plant, brand and date of
production.
GVWR: Gross Vehicle Weight Rating
GAWR FRT: Gross Axle Weight Rating
for the front Axle.
GAWR RR: Gross Axle Weight Rating
for the rear axle.Intended Outboard Sidewall: The side
of an asymmetrical tire, that must al-
ways face outward when mounted on a
vehicle.
Kilopascal (kPa): The metric unit for
air pressure.
Load Index: An assigned number rang-
ing from 1 to 279 that corresponds to
the load carrying capacity of a tire.
Maximum Inflation Pressure: The
maximum air pressure to which a cold
tire may be inflated. The maximum air
pressure is molded onto the sidewall.
Maximum Load Rating: The load rat-
ing for a tire at the maximum permis-
sible inflation pressure for that tire.
Maximum Loaded Vehicle Weight:
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight: The num-
ber of occupants a vehicle is designed
to seat multiplied by 150 pounds (68
kg).
