Seasonal Tire Types
Summer Tires
Your vehicle may be originally equipped with high performance summer tires or all season
tires. Tesla recommends using winter tires if
driving in cold temperatures or on roads
where snow or ice may be present. Contact
Tesla for winter tire recommendations.Warning: In cold temperatures or on
snow or ice, summer tires do not provide adequate traction. Selecting and installingthe appropriate tires for winter conditions
is important to ensure the safety and
optimum performance of your Model S,
even when equipped with dual-motors.
All-Season Tires
Your Model S may be originally equipped with
all-season tires. These tires are designed to provide adequate traction in most conditions
year-round, but may not provide the same level of traction as winter tires in snowy or icy
conditions. All-season tires can be
identifiedby “ALL SEASON" and/or "M+S” (mud and
snow) on the tire sidewall.
Winter Tires
Use winter tires to increase traction in snowy
or icy conditions. When installing winter tires,
always install a complete set of four tires at
the same time. Winter tires must be the same
size, brand, construction and tread pattern on all four wheels. Contact Tesla for winter tire
recommendations.
When equipped with winter tires, refer to the
tire warning label on the door pillar.
Winter tires can be identified by amountain/snowflake symbol on the
tire

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 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 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

(see Vehicle Loading on page 165).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.
