Consumer information and Reporting safety defects/Tire information
. Extra load tire
A tire designed to operate at higher
loads and higher inflation pressure
than the corresponding standard
tire.
. Groove
The space between two adjacent
tread ribs.
. Innerliner
The layer(s) forming the inside sur-
face of a tubeless tire that contains
the inflating medium within the tire.
. Innerliner separation
The parting of the innerliner from
cord material in the carcass.
. Intended outboard sidewall
(1) The sidewall that contains a
whitewall, 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
(2) The outward facing sidewall
of an asymmetrical tire that has a
particular side that must always
face outward when mounting on
a vehicle.
. Light truck (LT) tire
A tire designated by its manufac-
turer as primarily intended for use
on lightweight trucks or multipur-
pose passenger vehicles.
. Load rating
The maximum load that a tire is
rated to carry for a given inflation
pressure.
. Maximum inflation pressure
The maximum cold inflation pres-
sure to which a tire may be inflated.
. Measuring rim
The rim on which a tire is fitted for
physical dimension requirements.
. Normal occupant weight
150 lbs (68 kg) times the number of
occupants specified in the second
column of Table 1 that is appended
to the end of this section.
. Occupant distribution
Distribution of occupants in a vehi-
cle as specified in the third column
of Table 1 that is appended to the
end of this section.
. Maximum load rating . Open splice
The load rating for a tire at the
maximum permissible inflation
pressure for that tire. Any parting at any junction of tread,
sidewall, or innerliner that extends
to cord material.
. Maximum loaded vehicle weight . Outer diameter
The sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight
(d) Production options weight The overall diameter of an inflated
new tire.
. Maximum permissible inflation
pressure
The maximum cold inflation pres-
sure to which a tire may be inflated.
. Overall width
The linear distance between the
exteriors of the sidewalls of an
inflated tire, including elevations
due to labeling, decorations, or
protective bands or ribs.
