OPEN SPLICE
Any parting at any junction of tread, side wall, or inner liner that
extends to cord material.
OUTER DIAMETER
Then overall diameter of an inflated new tire.
OVERALL WIDTH
The linear distance between the exteriors of the side walls of an
inflated tire, including elevations due to labeling, decorations, or
protective band or ribs.
PLY
A layer of rubber-coated parallel cords.
PLY SEPARATION
A parting of rubber compound between adjacent plies.
PNEUMATIC TIRE
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
The combined weight of those installed regular production options
weighing over 2.3 kilograms (5 lbs.) 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
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
This is the inflation pressure provided by the vehicle manufacturer
on the Tire Information Label and the Certification/ VIN tag.
REINFORCED TIRE
A tire designed to operate at higher loads and at higher inflation
pressures than the corresponding standard tire.
RIM
A metal support for a tire or a tire and tube assembly upon which
the tire beads are seated.
RIM DIAMETER
This means the nominal diameter of the bead seat.
RIM SIZE DESIGNATION
This means the rim diameter and width.
RIM TYPE DESIGNATION
This means the industry of manufacturer’s designation for a rim by
style or code.
RIM WIDTH
This means the nominal distance between rim flanges.
SECTION WIDTH
The linear distance between the exteriors of the side walls of an
inflated tire, excluding elevations due to labeling, decoration, or
protective bands.
SIDEWALL
That portion of a tire between the tread and bead.
INNERLINER SEPARATION
The parting of the inner liner from cord material in the carcass.
INTENDED OUTBOARD SIDEWALL
The side wall that contains a white-wall, bears white lettering or
bears manufacturer, brand, and/or model name molding that is
higher or deeper than the same molding on the other side wall of
the tire or the outward facing side wall of an asymmetrical tire that
has a particular side that must always face outward when mounted
on a vehicle.
LIGHT TRUCK (LT) TIRE
A tire designed by its manufacturer as primarily intended for use on
lightweight trucks or multipurpose passenger vehicles.
LOAD RATING
The maximum load that a tire is rated to carry for a given inflation
pressure.
MAXIMUM LOAD RATING
The load rating for a tire at the maximum permissible inflation pres-
sure for that tire.
MAXIMUM PERMISSIBLE INFLATION PRESSURE
The maximum cold inflation pressure to which a tire may be in-
flated.
MAXIMUM LOADED VEHICLE WEIGHT
The sum of curb weight, accessory weight, vehicle weight, and pro-
duction options weight.
MEASURING RIM
The rim on which a tire is fitted for physical dimension require-
ments.
NON-PNEUMATIC RIM
A mechanical device which, when a non-pneumatic tire assembly
incorporates a wheel, supports the tire, and attaches, either inte-
grally or separably, to the wheel center member and upon which
the tire is attached.
NON-PNEUMATIC SPARE TIRE ASSEMBLY
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
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
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
This means 68 kilograms (150 lbs.) times the number of occu-
pants.
OCCUPANT DISTRIBUTION
The distribution of occupants in a vehicle as specified.
