flat tire TESLA MODEL S 2021 Owner´s Manual

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 front door is open.
The Tire Pressure indicator
light on the instrument panel alerts you if one or
more tires is under- or over-inflated.
The Tire Pressure indicator light does not immediately turn off when you adjust tire pressure. After inflating the tire to the
recommended pressure, you must drive over
15 mph (25 km/h) for more than 10 minutes to
activate the Tire Pressure Monitoring System
(TPMS), which turns
off the Tire Pressure
indicator light.
If the indicator light flashes for one minute
whenever you power on Model S, a fault with
the TPMS is detected (see TPMS Malfunction on page 192).
You can display tire pressures on the touchscreen by opening Controls > Service.
You can also choose whether you want to
display tire pressures using Bar or PSI by opening
Controls > Display > Tire Pressure.
WARNING: 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 the vehicle

Inspecting and Maintaining
Tires
Regularly 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
4/32” (3 mm) are more likely to
hydroplane in wet conditions and should not be used. Tires with a tread depth less than
5/32” (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
4/32” (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 6,250 miles (10,000 km) or if tread depth difference is 2/32 in (1.5 mm) or greater,
whichever comes first.
Unbalanced wheels (sometimes noticeable as
vibration through the steering yoke) affect
vehicle 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, install
the new tires on the rear if your vehicle

Replacing a Tire Sensor
If the Tire Pressure warning indicator displays
frequently, contact Tesla to determine if a tire
sensor needs to be replaced. If a non-Tesla
Service Center repairs or replaces a tire, the
tire sensor may not work until Tesla performs
the setup procedure.
TPMS Malfunction
Model S has also been equipped with a TPMS
malfunction indicator to indicate when the system is not operating properly.
The TPMS malfunction
indicator is combined with
the tire pressure indicator
light. When the system
detects a malfunction, the
indicator
flashes for
approximately one minute,
then remains continuously
lit. This sequence continues
upon subsequent vehicle
start-ups as long as the
malfunction exists. When
the TPMS malfunction
indicator is on, the system
might not be able to detect
or signal under-
or over-inflated tires as intended.
TPMS malfunctions can occur for a variety of reasons, including installing replacement or
alternate tires or wheels that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction indicator light
after replacing one or more tires or wheels on
your vehicle to ensure that the replacement tires or wheels allow the TPMS to continue to
function properly.
NOTE: If a tire has been replaced or repaired
using a different tire sealant than the one
available from Tesla, and a low tire pressure is
detected, it is possible that the tire sensor has
been damaged. Contact Tesla to have the
fault repaired as soon as possible.
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 installing the appropriate tires for winter conditions is important to ensure the safety and optimum performance of your Model S.
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
identified
by “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
diameter, brand, construction and tread
pattern on all four wheels. Contact Tesla for
winter tire recommendations.
Winter tires can be identified by a mountain/snowflake symbol on the
tire

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 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 219) 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 219. Exceeding
these boundaries can lead to significant
damage and overheating that is not covered
by the warranty.
Instructions for Transporters
218MODEL S Owner

While your vehicle is OK to drive when this alert is present, there is a chance that an issue affecting the primary power source could cause your vehicle to shut down unexpectedly.
It is recommended that you schedule service at your earliest opportunity, so the backup power source for the electrical system can be restored.
(VCSEC_a221)
Air pressure below recommendation for tires
Check pressure and refill air as needed
This alert does NOT indicate that there is a flat tire.
The tire pressure monitoring system (TPMS) has detected that the air pressure in one or more of your tires is at least 20% lower than the recommended cold tire pressure. This recommended
pressure should be displayed on the Tire and Loading information label.
See Maintaining Tire Pressures on page 188 for detailed information on how to keep the tires
properly inflated.
This alert may appear in cold weather because the air in your tires naturally contracts when it
becomes cold, decreasing tire pressures.

You can request Tesla roadside assistance options (mobile tire, loaner wheel, tow) if required.
See Contacting Tesla Roadside Assistance on page 217 for more information.
In a non-emergency situation, it is recommended that you visit your local Service Center for
assistance.
See Maintaining Tire Pressures on page 188 for detailed information on how to keep the tires
properly inflated.
The alert should clear once the Tire Pressure Monitoring System has a consistent tire pressure
measurement for each of your tires of at least 30 psi.
