The combined weight (in excess of those items replaced) of items available as factory
installed equipment.
The inner edge of a tire that is shaped to fit to the rim and form an air tight seal. The
bead is constructed of steel wires which are wrapped, or reinforced, by the ply cords.
The air pressure in a tire that has been standing in excess of three hours, or driven for less
than one mile.
The weight of a standard vehicle, including any optional equipment fitted, and with the
correct fluid levels.
The maximum permissible weight of a vehicle with driver, passengers, load, luggage, and
equipment.
A metric unit used to measure pressure. One kilo pascal equals approximately 0.145 psi.
The maximum pressure to which the tire should be inflated. This pressure is given on the
2
tire side wall in psi (lbf/in
CAUTION: This pressure marked on the tire is the maximum allowed by the tire
manufacturer. It is not the pressure Tesla recommends using for Model S.
The sum of curb weight, accessory weight, vehicle capacity weight, and production
options weight.
The combined weight of options installed which weigh in excess of 3 lb (1.4 kg) more
than the standard items that they replaced, and are not already considered in curb or
accessory weights.
Pounds per square inch (the unit used to measure tire pressure).
Tire inflation pressure, established by Tesla, which is based on the type of tires that are
mounted on the vehicle at the factory. This information can be found on the Tire and
Loading Information label located on the door pillar.
The metal support for a tire, or tire and tube, upon which the tire beads are seated.
The number of seats multiplied by 150 lbs (68 kg) plus the rated amount of load/luggage.
68 kilograms (150 lbs) times the number of occupants specified in the second column
of the tables for calculating load limits (see
Distribution of occupants in a vehicle.
A tire intended for use on passenger cars, multipurpose passenger vehicles, and
trucks, that have a gross vehicle weight rating (GVWR) of 10,000 lbs (4536 kg) or less.
Nominal diameter of the bead seat.
Rim diameter and width.
The manufacturing industry's designation for a rim by style or code.
Nominal distance between the rim's flanges.
