2015 TESLA MODEL S tire pressure

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 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.9Maximum tire load. The maximum load which can be carried by the tire.10Maximum permissible inflation pressure. This pressure should not be used for normal driving.11U.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.12Treadwear 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 200.13Traction 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.14Temperature 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.

Uniform Tire Quality Grading
The following information relates to the tire
grading system developed by the National
Highway Traffic Safety Administration
(NHTSA), which grades tires by tread wear,
traction and temperature performance. Tires
that have deep tread, and winter tires, are
exempt from these marking requirements.
Where applicable, quality grades are found on
the tire’s sidewall between the tread shoulder and maximum section width. For example:
• TREADWEAR 180
• TRACTION AA
• TEMPERATURE A
The quality grades are described next. Note: In addition to the marking requirements,
passenger car tires must conform to Federal Safety Requirements.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified government test course.
For example, a tire graded 150 wears one and
a half times better on a government test
course than a tire graded 100. The relative
performance of tires depends on the actual
conditions of their use, however, and can depart significantly from the norm due to
variations in driving habits, service practices, road characteristics, and climate.
Traction
The traction grades, from highest to lowest,
are: AA, A, B, and C. These grades represent a
tire’s ability to stop on wet pavement as
measured under controlled conditions on test
surfaces of asphalt and concrete. A tire
marked C might have poor traction performance.Warning: Defective tires are dangerous.
Do not drive if a tire is damaged,
excessively worn, or is inflated to an
incorrect pressure. The safety of the
vehicle and occupants can be adversely
affected. Check tires regularly for wear
and to ensure there are no cuts, bulges or
exposure of the ply/cord structure.Warning: The traction grade assigned to
the tire is based on straight-ahead
braking tests, and doesn’t include:acceleration, cornering, hydroplaning or
peak traction characteristics.
Temperature
The temperature grades are A (the highest), B, and C, representing the tire’s resistance tothe generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test wheel. Sustained high temperature cancause the tire to degenerate and reduce tirelife, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to the minimum
level of performance that all passenger car
tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A
represent levels of performance on the
laboratory test wheel that exceed the
minimum requirements.
Warning: A tire’s temperature grade is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in
combination, can cause heat buildup and
possible tire failure.

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/in).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

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/in)Pounds per square inch (the unit used to measure tirepressure).Recommended Tire Inflation
PressureTire inflation pressure, established by Tesla, which is based on the type of tires that are mounted on the vehicle at the factory.
