Tire Terminology and Definitions
Curb Weight: This means the weight of a motor
vehicle with standard and optional equipment including
the maximum capacity of fuel, oil and coolant, but
without passengers and cargo.
Air Pressure: The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure
is expressed in pounds per square inch (psi) or
kilopascal (kPa).
DOT Markings: A code molded into the sidewall of a
tire signifying that the tire is in compliance with the
U.S. Department of Transportation motor vehicle safety
standards. The DOT code includes the Tire Identification
Number (TIN), an alphanumeric designator which can
also identify the tire manufacturer, production plant,
brand and date of production.
Accessory Weight: This means the combined weight
of optional accessories. Some examples of optional
accessories are, automatic transmission, power steering,
power brakes, power windows, power seats, and air
conditioning.
Aspect Ratio: The relationship of a tire’s height to
its width.
GVWR: Gross Vehicle Weight Rating, see Loading
Your Vehicle on page 4-48.
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.
GAWR FRT: Gross Axle Weight Rating for the front
axle, see Loading Your Vehicle on page 4-48.
GAWR RR: Gross Axle Weight Rating for the rear axle,
Bead: The tire bead contains steel wires wrapped by

steel cords that hold the tire onto the rim.
Intended Outboard Sidewall: The side of an
asymmetrical tire that must always face outward when
mounted on a vehicle.
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.
Kilopascal (kPa): The metric unit for air pressure.
Cold Inflation 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. See Inflation - Tire Pressure on page 5-68.
There are 6.9 kPa’s to one psi.
Light Truck (LT-Metric) Tire: A tire used on light duty
trucks and some multipurpose passenger vehicles.
