FOR OWNERS,” included in your owner documentation package.

17OWNER SAFETY INFORMATION
MAINTAIN PROPER TIRE PRESSURESCheck tire pressures monthly when tires are cold and Model S has been parked
for over three hours. Inflate tires to the Tesla recommended inflation pressures,
printed on the Tire and Loading Information Label (see page 16). These
recommended pressures provide optimum ride and handling characteristics.
WARNINGS:Under-inflation is the most common cause of tire failures and can cause a tire
to overheat, resulting in severe tire cracking, tread separation, or “blowout”,
which causes unexpected loss of vehicle control and increased risk of injury.
Under-inflation also reduces Battery range and tire tread life.
Check tire pressures using an accurate pressure gauge when tires are
cold. It takes only one mile of driving to warm up the tires sufficiently to
affect tire pressures. Parking the vehicle in direct sunlight or in high ambient
temperatures can also affect tire pressures. If you must check warm tires,
expect increased pressures. Don’t let air out of warm tires in an attempt
to match recommended cold tire pressures. A hot tire at or below the
recommended cold tire inflation pressure is dangerously under-inflated.
To check and adjust tire pressures1. Remove the valve cap, then firmly press the tire gauge onto the valve.
2. If required, add air to reach the recommended pressure.
3. Re-check pressure by removing and re-attaching the tire gauge.
4. If you added too much air, release air by pushing on the metal stem in the
center of the valve. Re-check and adjust if necessary.
5. Screw the valve cap back on to prevent dirt from entering (periodically
inspect the valve cap for damage such as cracking).TIRE PRESSURE MONITORING SYSTEM (TPMS)Each tire should be checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-iinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and
it is the driver’s responsibility to maintain correct tire pressures, even if under-
inflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator light
to indicate when the system is not operating properly.
The TPMS malfunction indicator light is combined with the low tire pressure
telltale. When the sytem detects a malfunction, the telltale flashes for
approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator light is illuminated, the system may not be
able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function properly.
The tire pressure warning on the instrument panel alerts you
if one or more of your tires is significantly under-inflated. Stop
and check tire pressures as soon as possible, and inflate to
the recommended pressures
.
NOTE: The warning light does not turn off immediately after you adjust tire
pressures. It turns off when you drive Model S above 25 mph (40 km/h) for
more than 10 minutes with tires at the recommended pressures.
TIRE PRESSURES

20OWNER SAFETY INFORMATION
UNDERSTANDING TIRE MARKINGSFederal law requires tire manufacturers to place standardized information
on the sidewall of all tires. This information identifies and describes
the fundamental characteristics of the tire and also provides the tire
identification number (TIN) for safety standard certification and in case of
a recall.1 Tire 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 will be 102 mm.
4Tire construction. R indicates that the tire is of Radial ply construction.
5 Wheel 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 at which the tire can
be used for extended periods.
Q 99 T 118 V 149
R 106 U 124 W 168
S 112 H 130 Y 186
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.
9 Maximum tire load. The maximum load which can be carried by the tire.
10Maximum permissible inflation pressure. The maximum inflation pressure for
the tire. 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 numbers 1712
means 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, will last twice as long as a tire rated at 200. See
page 21.
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.
See page 21.
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. See page
21.
TIRE MARKINGS

21OWNER SAFETY INFORMATION
UNIFORM TIRE QUALITY GRADINGThe following information relates to the tire grading system developed by
the National Highway Traffic Safety Administration (NHTSA) which will
grade tires by tread wear, traction and temperature performance. Tires
that have deep tread, and winter tires, are exempt from these marking
requirements.Quality gradesWhere applicable, quality grades can be found on the tire sidewall
between the tread shoulder and maximum section width. For example:TREADWEAR 180 TRACTION AA TEMPERATURE AIn addition to the marking requirements, passenger car tires must conform
to Federal Safety Requirements.TreadwearThe 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 would wear 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 may
depart significantly from the norm due to variations in driving habits,
service practices, and differences in road characteristics and climate.TractionThe 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 may have poor traction performance.
WARNINGS:
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 will be adversely affected. Check tires regularly for wear and to
ensure there are no cuts, bulges or exposure of the ply/cord structure.
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.
TemperatureThe temperature grades are A (the highest), B, and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the tire to degenerate
and reduce tire life, 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.
Tire performance decreases at low ambient temperatures, resulting in
reduced grip and increased susceptibility to damage from impacts. In
temperatures below 15° F (-10° C), winter tires are recommended. Contact
Tesla for recommended winter tire specifications.
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.
