malfunction indicator is on, the system might not be able to detect or signal
under-inflated tires as intended.
TPMS malfunctions can occur for a variety of reasons,
including installing replacement or alternate tires or wheels that prevent the TPMS from functioning properly. Always check the TPMS malfunction indicator light after replacing one or more tires or wheels on your vehicle to
ensure that the replacement tires or wheels allow the
TPMS to continue to function properly.
NOTE: If a tire has been replaced or repaired using a
different tire sealant than the one available from Tesla,
and a low tire pressure is detected, it is possible that the tire sensor has been damaged. Contact Tesla to have the fault repaired as soon as possible.
Seasonal Tire Types
Understand Your Tire Type
The type of tires that your vehicle is originally equipped
with depends on vehicle model and market region. It is important to understand the capabilities of your vehicle

8. Load range: Shown as Standard Load (SL) or Extra Load (XL), the load range determines how much weight your
tires can support at a
specified tire pressure. When replacing tires, only use tires of the same load range. If towing
with snow tires, ensure they are the same load range of the tires your vehicle came equipped with.
9.
Tire composition and materials: The number of plies in both the tread area and the sidewall area indicates how
many layers of rubber coated material make up the structure of the tire. Information is also provided on the type
of materials used.
10.
Maximum tire load: The maximum load which can be carried by the tire.
11.
Maximum permissible inflation pressure: This pressure should not be used for normal driving.
12.
U.S. DOT Tire Identification Number (TIN): Begins with the letters DOT and indicates that the tire meets all federal
standards. The next 2 digits/letters represent the plant code where it was manufactured, and the last 4 digits represent the week and year of manufacture. For example, the number 1712 is used to represent the 17th week of 2012. The other numbers are marketing codes used at the manufacturer

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 Y.
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.
