Understanding Tire MarkingsLaws require tire manufacturers to place standardized information on the sidewall of all tires. Thisinformation
identifies and describes the fundamental characteristics of the tire.
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).8Tire composition and materials. The number of plies in both the tread area and thesidewall 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.9Maximum tire load. The maximum load which can be carried by the tire.

Tire and Loading GlossariesGeneral Wheel and Tire TermsAccessory 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 PressureThe 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 X.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 InflationPressureTire 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 specifiedin the second column of the tables for calculating load limits
(see Vehicle Loading on page 178).Occupant distributionDistribution of occupants in a vehicle.Passenger car tireA tire intended for use on passenger cars, multipurpose
passenger vehicles, and trucks, that have a gross vehicle weight
rating (GVWR) of 10,000 pounds or less.
