Intended Outboard Sidewall:The
side of an asymmetrical tire, that
must always face outward when
mounted on a vehicle.
Kilopascal (kPa): The metric unit for
air pressure.
Light truck(LT) tire: A tire designat-
ed by its manufacturer as primarily
intended for use on lightweight trucks
or multipurpose passenger vehicles.
Load ratings: The maximum load
that a tire is rated to carry for a given
inflation pressure.
Load Index: An assigned number
ranging from 1 to 279 that corre-
sponds to the load carrying capacity
of a tire.
Maximum Inflation Pressure: The
maximum air pressure to which a
cold tire may be inflated. The maxi-
mum air pressure is molded onto the
sidewall. Maximum Load Rating:
The load rat-
ing for a tire at the maximum permissi-
ble inflation pressure for that tire.
Maximum Loaded Vehicle Weight:
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight: The
number of occupants a vehicle is
designed to seat multiplied by 150
pounds (68 kg).
Occupant Distribution: Designated
seating positions.
Outward Facing Sidewall: The side
of a asymmetrical tire that has a par-
ticular side that faces outward when
mounted on a vehicle. The outward
facing sidewall bears white lettering
or bears manufacturer, brand, and/or
model name molding that is higher or
deeper than the same moldings on
the inner facing sidewall.
Passenger (P-Metric) Tire: A tire
used on passenger cars and some
light duty trucks and multipurpose
vehicles. Ply:
A layer of rubber-coated parallel
cords
Pneumatic tire: A mechanical
device made of rubber, chemicals,
fabric and steel or other materials,
that, when mounted on an automo-
tive wheel, provides the traction and
contains the gas or fluid that sustains
the load.
Production options weight: The
combined weight of installed regular
production options weighing over 5
lb.(2.3 kg) in excess of the standard
items which they replace, not previ-
ously considered in curb weight or
accessory weight, including heavy
duty brakes, ride levelers, roof rack,
heavy duty battery, and special trim.
Recommended Inflation Pressure:
Vehicle manufacturer's recommend-
ed tire inflation pressure and shown
on the tire placard.
Radial Ply Tire: A pneumatic tire in
which the ply cords that extend to the
beads are laid at 90 degrees to the
centerline of the tread.
