Bead separation means a breakdown of the bond
between components in the bead.
Bias ply tire means a pneumatic tire in which the ply
cords that extend to the beads are laid at alternate angles
substantially less than 90 degrees to the centerline of the
tread.
Carcass means the tire structure, except tread and
sidewall rubber which, when inflated, bears the load.
Chunking means the breaking away of pieces of the
tread or sidewall.
Cord means the strands forming the plies in the tire.
Cord separation means the parting of cords from
adjacent rubber compounds.
Cracking means any parting within the tread, sidewall, or
inner liner of the tire extending to cord material.
Curb weight means the weight of a motor vehicle with
standard equipment including the maximum capacity of
fuel, oil, and coolant, and, if so equipped, air conditioning
and additional weight optional engine.
Cold inflation pressure means the tire pressure when
the vehicle hasn't been driven for at least three hours.
Extra load tire means a tire designed to operate at higher
loads and higher inflation pressure than the corresponding
standard tire.
Groove means the space between two adjacent tread
ribs.
Gross Axle Weight Rating or GAWR means the value
specified by the vehicle manufacturer as the load-carrying
capacity of a single axle system, as measured at the tire-
ground interfaces.
Gross vehicle weight rating or GVWR means the value
specified by the manufacturer as the loaded weight of a
single vehicle.
Hitch Weight means the downward force exerted on the
hitch ball by the trailer coupler.
Innerliner means the layer(s) forming the inside surface
of a tubeless tire that contains the inflating medium within
the tire.
Innerliner separation means the parting of the innerliner
from cord material in the carcass.
Light truck (LT) tire means a tire designated by its
manufacturer as primarily intended for use on lightweight
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.
24
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
column of Table I of 49 CFR 571.110.
Occupant distribution means distribution of occupants
in a vehicle as specified in the third column of Table I of
49 CFR 571.110.
Open splice means any parting at any junction of tread,
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.
