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

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 tire.
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 means the industry of 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.

Tread rib means a tread section running circumferentially
around a tire.
Tread separation means pulling away of the tread from the
tire carcass.
Treadwear indicators (TWI) means the projections within the
principal grooves designed to give a visual indication of the
degrees of wear of the tread.
Vehicle capacity weight means the rated cargo and luggage
load plus 68 kilograms times the vehicle's designated seating
capacity.
Vehicle maximum load on the tire means that load on an
individual tire that is determined by distributing to each axle
its share of the maximum loaded vehicle weight and dividing
by two.
Vehicle normal load on the tire means that load on an
individual tire that is determined by distributing to each axle
its share of the curb weight, accessory weight, and normal
occupant weight (distributed in accordance with Table I of 49
CFR 571.110) and dividing by 2.
Wheel center member means, in the case of a non-
pneumatic tire assembly incorporating a wheel, a mechanical
device which attaches, either integrally or separably, to the
non-pneumatic rim and provides the connection between
the non-pneumatic rim and the vehicle; or in the case of
a nonpneumatic tire assembly not incorporating a wheel,
a mechanical device which attaches, either integrally or
