22OWNER SAFETY INFORMATION
WHEELS AND TIRES GLOSSARYAccessory weightThe combined weight (in excess of those items replaced) of items available as factory installed equipment.
BeadThe 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 pressureThe air pressure in a tire which has been standing in excess of three hours, or driven for less than one mile.
Curb weightThe weight of a standard vehicle, including any optional equipment fitted, and with the correct fluid levels.
Gross vehicle weightThe 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 pressureThe maximum pressure to which the tire should be inflated. This pressure is given on the tire side wall in psi (lbf/in2).
This pressure is the maximum allowed by the tire manufacturer. It is not the pressure recommended for use.
Maximum loaded vehicle
weightThe sum of curb weight, accessory weight, vehicle capacity weight, and production options weight.
Production options weightThe combined weight of options installed which weigh in excess of 3 lbs more than the standard items that they replaced, and are not
already considered in curb or accessory weights.
PSI (lbf/in2)Pounds per square inch, unit of measure for pressure.
RimThe metal support for a tire, or tire and tube, upon which the tire beads are seated.
Vehicle capacity weightThe number of seats multiplied by 150 lbs plus the rated amount of load/luggage.

23OWNER SAFETY INFORMATION
VEHICLE LOAD LIMIT
WARNINGS:
Overloading the vehicle will have an adverse effect on braking and
handling, which could compromise your safety or damage Model S.
Therefore you must understand how much weight your Model S can
safely carry. This weight is called the vehicle capacity weight and includes
the weight of all occupants, cargo and any additional equipment fitted to
Model S since it was manufactured.
Always ensure tires are inflated to their recommended levels. Doing so is
especially important when carrying heavy loads.
To calculate load limit1. Locate the statement “The combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs” on your vehicle’s TIRE AND
LOADING INFORMATION label (illustrated on page 16).
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage
load capacity. For example, if the “XXX” amount equals 1400 lbs,
and there will be five 150 lb (68 kg) passengers in the vehicle,
the amount of available cargo and luggage capacity is 650 lbs.
(1400 - 750 (5 x 150) = 650 lbs).
5. Determine the combined weight of luggage and cargo being loaded on
the vehicle. That weight may not safely exceed the available cargo and
luggage load capacity calculated in Step 4.
Example load limit calculationHow much cargo you can carry in Model S depends on the number and
weight of passengers. The following are typical examples of calculated
load limits. These examples assume passengers weighing 150 lbs (68 kg).
If the passengers weigh more or less, the available cargo and luggage
load capacity will decrease or increase respectively.
Example 1: Driver and one passengerDescription Total
Vehicle Capacity Weight 954 lbs
Subtract Occupant Weight (2 x 150 lbs) 300 lbs
Available Cargo Weight 654 lbsExample 2: Driver and four passengersDescription Total
Vehicle Capacity Weight 954 lbs
Subtract Occupant Weight (5 x 150 lbs) 750 lbs
Available Cargo Weight 204 lbsThe available cargo or luggage weight should then be distributed between
the front trunk and the trunk.
CAUTION: Never load more than 300 lbs (136 kg) into the front trunk.
