tire size TESLA MODEL S 2023 Owners Manual

If tires need to be replaced early, for example due to a
flat tire, we recommend replacing the tires in pairs
unless the other tires are within
2/32 in (1.5 mm) of tread
depth of the new tire. When replacing tires, it is important to match the brand and model of the older
tires. Always place a pair of new tires on the rear if all four tires are the same size. Always balance the wheel and tire after replacing a tire. Consult with a professional tire retailer and installer for further guidance.
NOTE: Regardless of the number of tires replaced, a
complete set of matching tires is recommended for
optimum performance.
If tires other than those specified are used, ensure that
the load and speed ratings marked on the tire
(see
Understanding Tire Markings on page 195) equal or
exceed those of the original
specification.
For the specification of the original wheels and tires
installed on
Model S, see Wheels and Tires on page 194.
If you replace a wheel, the TPMS (Tire Pressure Monitoring System) sensors need to be reset to ensure they provide accurate warnings when tires are under-
or
over-inflated (see Automatic Reset of TPMS Sensors on
page 176).
WARNING: For your safety, use only tires and
wheels that match the original specification. Tires
that do not match the original specification can
affect the operation of the TPMS.
WARNING: Never exceed the speed rating of your
vehicle

the size indicated on the vehicle placard or tire inflation
pressure label, determine the proper tire inflation
pressure for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that displays a tire pressure telltale (Tire Pressure Warning) on the
instrument panel
when one or more of your tires is significantly under- or
over-inflated. Accordingly, when the Tire Pressure
indicator light displays on the
instrument panel to alert
you about tire pressure, stop and check your tires as soon as possible, and
inflate them to the proper pressure
(see
Maintaining Tire Pressures on page 173). Driving on
a
significantly under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also
reduces range
efficiency and tire tread life, and may
affect the vehicle

General Wheel and Tire Terms
Accessory 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 that 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
Pressure
The maximum pressure to which the tire should be inflated. This pressure is given on the
tire side wall in psi (lbf/in2).
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.
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 lb (1.4 kg) 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 (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.
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 (68 kg) plus the rated amount of load/luggage.
