Cold Tire Pressure:The amount of
air pressure in a tire, measured in
kilopascals (kPa) or pounds per
square inch (psi) before a tire has
built up heat from driving.
Curb Weight:This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings:A code molded into
the sidewall of a tire signifying that
the tire is in compliance with the U.S.
Department of Transportation motor
vehicle safety standards. The DOT
code includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.GVWR:Gross Vehicle Weight Rating
GAWR FRT:Gross Axle Weight
Rating for the Front Axle.
GAWR RR:Gross Axle Weight
Rating for the Rear axle.
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 Index:An assigned number
ranging from 1 to 279 that corre-
sponds to the load carrying capacity
of a tire.
Load ratings:The maximum load
that a tire is rated to carry for a given
inflation pressure.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
rating for a tire at the maximum per-
missible 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
lbs. (68kg).
