Maintaining Tire Pressures
Keep tires
inflated to the pressures shown on
the Tire and Loading Information label, even if
it
differs from the pressure printed on the tire
itself. The Tire and Loading Information label is
located on the center door pillar and is visible
when the driver
Inspecting and Maintaining TiresRegularly inspect the tread and side walls for
any sign of distortion (bulges), foreign objects,
cuts or wear.Warning: Do not drive Model S if a tire is
damaged, excessively worn, or inflated to
an incorrect pressure. Check tires
regularly for wear, and ensure there are
no cuts, bulges or exposure of the ply/
cord structure.
Tire Wear
Adequate tread depth is important for proper
tire performance. Tires with a tread depth less
than 3 mm are more likely to hydroplane in
wet conditions and should not be used. Tires
with a tread depth less than 4 mm do not
perform well in snow and slush and should not
be used when driving in winter conditions.
Model S is originally
fitted with tires that have
wear indicators molded into the tread pattern. When the tread has been worn down to 3 mm,
the indicators start to appear at the surface of
the tread pattern, producing the
effect of a
continuous band of rubber across the width of
the tire. For optimal performance and safety,
Tesla recommends replacing tires before the
wear indicators are visible.
Tire Rotation, Balance, and Wheel Alignment
Tesla recommends rotating the tires every
10,000 km.
Unbalanced wheels (sometimes noticeable as
vibration through the steering wheel)
affectvehicle handling and tire life. Even with regular
use, wheels can get out of balance. Therefore,
they should be balanced as required.
If tire wear is uneven (on one side of the tire
only) or becomes abnormally excessive, check
the alignment of wheels.
Note: When replacing only two tires, always
install the new tires on the rear.
Punctured Tires
A puncture eventually causes the tire to lose
pressure, which is why it is important to check tire pressures frequently. Permanently repair
or replace punctured or damaged tires as
soon as possible.
Your tubeless tires may not leak when
penetrated, provided the object remains in the
tire. If, however, you feel a sudden vibration or
ride disturbance while driving, or you suspect a tire is damaged, immediately reduce your
speed. Drive slowly, while avoiding heavy
braking or sharp steering and, when safe to do so, stop the vehicle. Arrange to have Model S
transported to a Tesla Service Center, or to a nearby tire repair center.
Note: In some cases, you can temporarily
repair small tire punctures (under 6 mm) using
an optional tire repair kit available from Tesla.
This allows you to slowly drive Model S to Tesla or to a nearby tire repair facility.Warning: Do not drive with a punctured
tire, even if the puncture has not caused the tire to
deflate. A punctured tire candeflate suddenly at any time.
Flat Spots
If Model S is stationary for a long period in
high temperatures, tires can form
flat spots.
When Model S is driven, these flat spots cause
a vibration which gradually disappears as the
tires warm up and regain their original shape.
To minimize
flat spots during storage, inflatetires to the maximum pressure indicated on the tire wall. Then, before driving, release airto adjust tire pressure to the recommended
levels.
Improving Tire Mileage To improve the mileage you get from your
tires, maintain tires at the recommended tire
pressures, observe speed limits and advisory
speeds, and avoid:
Replacing Tires and Wheels
Tires degrade over time due to the
effects of
ultraviolet light, extreme temperatures, high
loads, and environmental conditions. It is
recommended that tires are replaced every six
years, or sooner if required.
Wheel and tires are matched to suit thehandling characteristics of the vehicle.
Replacement tires must comply with the
original
specification. If tires other than thosespecified are used, ensure that the load and
speed ratings marked on the tire (see Understanding Tire Markings on page 172)
equal or exceed those of the original
specification.
Ideally, you should replace all four tires at the same time. If this is not possible, replace the
tires in pairs, placing the new tires on the rear.
Always balance the wheel after replacing a
tire.
If you replace a wheel, the TPMS (Tire Pressure
Monitoring System) sensors need to be reset to ensure they provide accurate warnings
when tires are under- or
over-inflated (see
Resetting the TPMS Sensors on page 152).
For the
specification of the original wheels
and tires installed on Model S, see Wheels and
Tires on page 171.
Warning: For your safety, use only tires
and wheels that match the original
specification. Tires that do not match the
original specification can affect the
operation of the TPMS.
Warning: Never exceed the speed rating
of your vehicle
Tire Pressure MonitoringEach tire should be checked monthly when
cold and
inflated to the recommended
pressures that are printed on the Tire and
Loading Information label located on the driver
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

When Transporting Model SAlways transport Model S with all four tires
offthe ground. A flatbed truck or comparable
transport vehicle is recommended. A wheel lift
and dolly can be used only when transporting
Model S for a maximum of 15 miles (25 km), provided the driving speed does not exceed45 mph (70 km/h). When transporting,
whether on a
flatbed truck or using a wheel
lift and dolly, Model S can face either direction.
Do not transport Model S using any other method unless
specified by Tesla. Follow the
steps provided and observe all warnings and
cautions. Damage caused by transporting your
vehicle is not covered by the warranty.
Note: The following illustrations are for
demonstration purposes only.
Warning: Model S is equipped with high
voltage components (see High Voltage
Components on page 138). Before
transporting Model S as a result of an
event (such as a collision) that may have
compromised a high voltage component, it is important to assume that these
components are energized. Always follow
high voltage safety precautions (wearing
personal protective equipment, etc.) until
emergency response professionals have
evaluated the vehicle and can accurately
confirm that all high voltage systems are
no longer energized. Failure to do so may
result in serious injury or death.
Disable Self-Leveling (air
suspension vehicles only)
If Model S is equipped with Smart Air
Suspension, it automatically self-levels, even
when power is
off. To prevent damage, you
must activate Jack mode to disable self- leveling:
1. Touch Controls > Suspension on the
touchscreen.
2. Press the brake pedal, then touch Very
High to maximize height.
3. Touch Jack.
Note:
Jack mode cancels when Model S is
driven over 4 mph (7 km/h).Warning: Failure to activate Jack mode
on a Model S equipped with Smart Air
Suspension can result in the vehicle
becoming loose during transport, which
may cause
significant damage.
Activate Tow Mode
Model S may automatically shift into Park
when it detects the driver leaving the vehicle,
even if it has previously been shifted into
Neutral. To keep Model S in Neutral (which
disengages the parking brake), you must use
the touchscreen to activate Tow mode:
1. Shift into Park.
2. Chock the tires or otherwise ensure
Model S is stable.
3. Press and hold the brake pedal, then on
the touchscreen touch Controls >
Settings > Service & Reset > Tow Mode >
ON .
When Tow mode is active, Model S
displays this indicator light on the
instrument panel, along with a
message telling you that Model S is
free-rolling.
To cancel Tow Mode, shift Model S into Park.
Caution: If the electrical system is not
working, and you therefore cannot release
the electric parking brake, attempt to
jump start the 12V battery. For
instructions, call Tesla Roadside
Assistance. If a situation occurs where
you cannot disengage the parking brake,
use a self-loading dolly or tire skates.
Before doing so, always check the
manufacturer
