Understanding Tire Markings
Laws require tire manufacturers to place standardized information on the sidewall of all tires. This information
identifies and describes the fundamental characteristics of the tire. It also provides the tire identification number
(TIN) for certification of safety standards, and in case of a recall.
1Tire category. P indicates that the tire is for passenger vehicles.2Tire width. This 3-digit number is the width (in millimeters) of the tire from sidewall edge to sidewall edge.3Aspect ratio. This 2-digit number is the sidewall height as a percentage of the tread width. So, if the tread width is 205 mm, and the aspect ratio is 50, the sidewall height is 102 mm.4Tire construction. R indicates that the tire is of Radial ply construction.5Wheel diameter. This 2-digit number is the diameter of the wheel rim in inches.6Load index. This 2 or 3-digit number is the weight each tire can support. This number is not always shown.7Speed rating. When stated, indicates the maximum speed (in mph) at which the tire can be used for
extended periods. Q=99 mph (160 km/h), R=106 mph (170 km/h), S=112 mph (180 km/h), T=118 mph (190 km/h), U=124 mph (200 km/h), H=130 mph (210 km/h), V=149 mph (240 km/h), W=168 mph
(270 km/h), Y=186 mph (300 km/h).

8Load 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.
9Tire 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.10Maximum tire load. The maximum load which can be carried by the tire.11Maximum permissible inflation pressure. This pressure should not be used for normal driving.12U.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’s discretion. This
information can be used to contact consumers if a tire defect requires a recall.13Treadwear grade. This number indicates the tire’s wear rate. The higher the treadwear number is, the longer it
should take for the tread to wear down. A tire rated at 400, for example, lasts twice as long as a tire rated at
200.14Traction grade. Indicates a tire’s ability to stop on wet roads. A higher graded tire should allow you to stop
your vehicle in a shorter distance than a tire with a lower grade. Traction is graded from highest to lowest as
AA, A, B, and C.15Temperature grade. The tire’s resistance to heat is grade A, B, or C, with A indicating the greatest resistance.
This grading is provided for a correctly
inflated tire, which is being used within its speed and loading limits.

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 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 plus the rated amount of load/luggage.
Load Carrying Definitions
Normal occupant weight68 kilograms (150 lbs) times the number of occupants specified in the second column
of the tables for calculating load limits (see
Vehicle Loading on page 179).
