flat tire TESLA MODEL S 2023 Owners Manual

If tires need to be replaced early, for example due to a
flat tire, we recommend replacing the tires in pairs
unless the other tires are within
2/32 in (1.5 mm) of tread
depth of the new tire. When replacing tires, it is important to match the brand and model of the older
tires. Always place a pair of new tires on the rear if all four tires are the same size. Always balance the wheel and tire after replacing a tire. Consult with a professional tire retailer and installer for further guidance.
NOTE: Regardless of the number of tires replaced, a
complete set of matching tires is recommended for
optimum performance.
If tires other than those specified are used, ensure that
the load and speed ratings marked on the tire
(see
Understanding Tire Markings on page 195) equal or
exceed those of the original
specification.
For the specification of the original wheels and tires
installed on
Model S, see Wheels and Tires on page 194.
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 Automatic Reset of TPMS Sensors on
page 176).
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

the size indicated on the vehicle placard or tire inflation
pressure label, determine the proper tire inflation
pressure for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that displays a tire pressure telltale (Tire Pressure Warning) on the
instrument panel
when one or more of your tires is significantly under- or
over-inflated. Accordingly, when the Tire Pressure
indicator light displays on the
instrument panel to alert
you about tire pressure, stop and check your tires as soon as possible, and
inflate them to the proper pressure
(see
Maintaining Tire Pressures on page 173). Driving on
a
significantly under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also
reduces range
efficiency and tire tread life, and may
affect the vehicle

8. Tire 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.
10.
Maximum permissible inflation pressure: This pressure should not be used for normal driving.
11.
U.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

DO NOT TRANSPORT WITH
WHEELS ON THE GROUND
The front and rear motors in Model S generate power
when the wheels spin. Always transport
Model S with all
four tires
off the ground. Ensure that the tires are unable
to spin at any time during transport.
WARNING: NEVER TRANSPORT YOUR VEHICLE
WITH THE TIRES IN A POSITION WHERE THEY
CAN SPIN. DOING SO CAN LEAD TO SIGNIFICANT
DAMAGE AND OVERHEATING. IN RARE CASES
EXTREME OVERHEATING MAY CAUSE THE
SURROUNDING COMPONENTS TO IGNITE.
Do not transport Model S using any method that is not
specified by Tesla. Adhere to the instructions provided in
the following sections and observe all warnings and
cautions provided. Damage caused by improper
transporting of your vehicle is not covered by the
warranty.
NOTE: Tesla is not liable or responsible for reimbursing
services not dispatched through Tesla Roadside Assistance.
Approved Methods for Transporting
A flatbed truck or comparable transport vehicle is the
recommended method of transporting
Model S. The
vehicle can face either direction when using a
flatbed.
If Model S must be transported without a flatbed truck,
then wheel lifts and dollies must be used to ensure that
all four wheels are
off of the ground. This method may
only be used for a maximum of
35 miles (55 km), and
must not exceed the manufacturer speed rating of the
dollies. With this method, Tesla recommends the vehicle
faces forward so that the front wheels are lifted and the rear wheels are on dollies.
NOTE: Transporting Model S with the front wheels on
dollies is not recommended, but may be done if an
external
steering yoke (or steering wheel) lock is applied
and care is taken to prevent the front wheels from
spinning.
CAUTION: DO NOT TRANSPORT YOUR VEHICLE
IF THERE IS ANY CHANCE OF ANY OF THE
WHEELS SPINNING.
CAUTION: Enable Transport Mode (see Activate
Transport Mode on page 203) before winching
Model S onto a flatbed truck. If Transport Mode is
not available or the touchscreen is not accessible,
self-loading dollies or tire skates must be used to
load the vehicle into the approved transportation
position. Tesla is not responsible for any damage
caused by or during the transport of Model S,
including personal property damage or damage
caused by using self-loading dollies or tire skates.
NOTE: Transport Mode is only intended to allow for
winching
Model S onto a flatbed truck or repositioning
the vehicle out of a parking space. While in Transport Mode, the tires are allowed to rotate slowly (under
3
mph or 5 km/h) and for a very short distance (less than
30 feet or 10 meters). See Activate Transport Mode on
page 203. Exceeding these boundaries can lead to
significant damage and overheating that is not covered
by the warranty.
WARNING: Model S is equipped with high voltage
components that may be compromised as a result
of a collision (see High Voltage Components on
page 159). Before transporting Model S, it is
important to assume these components are
energized. Always follow high voltage safety
precautions (wearing personal protection
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.
Instructions for Transporters
202MODEL S Owner

This alert indicates that one or more of the tires on your vehicle is extremely low or flat.
The tire pressure monitoring system (TPMS) has detected that the air pressure in one or more of your tires is
significantly lower than the recommended cold tire pressure.
What to do:
You should pull over carefully as soon as possible. In a safe location, check for a flat tire.
You can request Tesla roadside assistance options (mobile tire, loaner wheel, tow) if required. See Contacting Tesla
Roadside Assistance on page 201 for more information.
In a non-emergency situation, it is recommended that you visit a local tire shop for assistance or schedule service
using your Tesla Mobile App.
See Maintaining Tire Pressures on page 173 for detailed information on where to find the recommended cold
pressure (RCP) for your vehicle
