trucks or multipurpose passenger vehicles.
Load rating means the maximum load that a tire is rated
to carry for a given inflation pressure.
Maximum load rating means the load rating for a tire at
the maximum permissible inflation pressure for that tire.
Maximum permissible inflation pressure means the
maximum cold inflation pressure to which a tire may be
inflated.
Maximum loaded vehicle weight means the sum of (a)
Curb weight; (b) Accessory weight; (c) Vehicle capacity
weight; and (d) Production options weight.
Measuring rim means the rim on which a tire is fitted for
physical dimension requirements.
Non-pneumatic rim means a mechanical device which,
when a non-pneumatic tire assembly incorporates a
wheel, supports the tire, and attaches, either integrally or
separably, to the wheel center member and upon which
the tire is attached.
Non-pneumatic spare tire assembly means a non-
pneumatic tire assembly intended for temporary use in
place of one of the pneumatic tires and rims that are fitted
to a passenger car in compliance with the requirements
of this standard.
Non-pneumatic tire means a mechanical device which
transmits, either directly or through a wheel or wheel
center member, the vertical load and tractive forces from
the roadway to the vehicle, generates the tractive forces
that provide the directional control of the vehicle and
does not rely on the containment of any gas or fluid for
providing those functions.
Non-pneumatic tire assembly means a non-pneumatic
tire, alone or in combination with a wheel or wheel center
member, which can be mounted on a vehicle.
Normal occupant weight means 68 kilograms (150 lbs.)
times the number of occupants specified in the second

sidewall, or innerliner that extends to cord material.
Outer diameter means the overall diameter of an inflated
new tire.

Overall width means the linear distance between the
exteriors of the sidewalls of an inflated tire, including
elevations due to labeling, decorations, or protective
bands or ribs.
Passenger car tire means a tire intended for use on
passenger cars, multipurpose passenger vehicles, and
trucks, that have a gross vehicle weight rating (GVWR) of
10,000 pounds or less.
Pin weight means the downward force applied to the 5th
wheel or gooseneck ball, by the trailer kingpin or
gooseneck coupler.
Ply means a layer of rubber-coated parallel cords.
Ply separation means a parting of rubber compound
between adjacent plies.
Pneumatic tire means a mechanical device made of
rubber, chemicals, fabric and steel or other materials,
that, when mounted on an automotive wheel, provides
the traction and contains the gas or fluid that sustains the
load.
Production options weight means the combined weight of
those installed regular production options weighing over
2.3 kilograms in excess of those standard items which
they replace, not previously considered in curb weight or
accessory weight, including heavy duty brakes, ride
levelers, roof rack, heavy duty battery, and special trim.
Radial ply tire means a pneumatic tire in which the ply
cords that extend to the beads are laid at substantially 90
degrees to the centerline of the tread.
Recommended inflation pressure means the proper Cold
Inflation Pressure as shown on the Tire Information label.
Reinforced tire means a tire designed to operate at
higher loads and at higher inflation pressures than the
corresponding standard fire.
Rim means a metal support for a tire or a tire and tube
assembly upon which the tire beads are seated.
Rim diameter means nominal diameter of the bead seat.
Rim size designation means rim diameter and width.
Rim type designation
manufacturer's designation for a rim by style or code.
Rim width means nominal distance between rim flanges.
Section width means the linear distance between the
exteriors of the sidewalls of an inflated tire, excluding
elevations due to labeling, decoration, or protective
bands.
Sidewall means that portion of a tire between the tread
and bead.
Sidewall separation means the parting of the rubber
compound from the cord material in the sidewall.
ST tire means a tire designed for use only on trailers
drawn on a road.
Test rim means the rim on which a tire is fitted for testing,
and may be any rim listed as appropriate for use with that
tire.
