WARNING:
A tire’s temperature grade is established for a tire that is properly inflated
and not overloaded. Excessive speed, under-inflation, or excessive loading, either
separately or in combination, can cause heat buildup and possible tire failure.
Tire and Loading Glossaries
General Wheel and Tire Terms
Accessory Weight
The combined weight (in excess of those items replaced) of items
available as factory installed equipment.
Bead
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.
Cold Tire Pressure
The air pressure in a tire that has been standing in excess of three
hours, or driven for less than one mile.
Curb Weight
The weight of a standard vehicle, including any optional equipment
fitted, and with the correct fluid levels.
Gross Vehicle Weight The maximum permissible weight of a vehicle with driver, passengers,
load, luggage, and equipment.
kPa (kilo pascal)
A metric unit used to measure pressure. One kilo pascal equals
approximately 0.145 psi.
Maximum Inflation
Pressure
The maximum pressure to which the tire should be inflated. This
pressure is given on the tire side wall in psi (lbf/in
2
).
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 X.
Maximum Loaded
Vehicle Weight
The sum of curb weight, accessory weight, vehicle capacity weight,
and production options weight.
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.
PSI (lbf/in
2
)
Pounds per square inch (the unit used to measure tire pressure).
Recommended Tire
Inflation 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.
Rim
The metal support for a tire, or tire and tube, upon which the tire
beads are seated.
Vehicle Capacity
Weight
The number of seats multiplied by 150 lbs (68 kg) plus the rated
amount of load/luggage.
