Gross Vehicle WeightThe maximum permissible weight of a vehicle with driver, 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
Pressure
The maximum pressure to which the tire should be inflated. This pressure is given on the
tire side wall in psi (lbf/in2).
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 Y.
Maximum Loaded

Wheels and Tires
220MODEL Y Owner
DO NOT TRANSPORT WITH
WHEELS ON THE GROUND
The motors in Model Y generate power when the wheels
spin. Always transport
Model Y 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 Y 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 Y. The
vehicle can face either direction when using a
flatbed.
If Model Y 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
facing forward so that the front wheels are lifted and the rear wheels are on dollies.CAUTION: Enable Transport Mode (see Activate
Transport Mode on page 223) before winching Model
Y onto a flatbed truck (see Pull Onto Flatbed Truck
From Front on page 224 and Pull Onto Flatbed Truck
From Rear on page 224). 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 Y,
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 Y 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 223. Exceeding these boundaries can lead to
significant damage and overheating that is not covered
by the warranty.
WARNING: Model Y is equipped with high voltage
components that may be compromised as a result
of a collision (see High Voltage Components on
page 165). Before transporting Model Y, 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.
Activate Transport Mode
Transport Mode keeps the parking brake disengaged
while winching
Model Y onto a flatbed truck. When
active, Transport Mode displays a message indicating that the vehicle will remain free-rolling. To enable
Transport Mode:
1. Ensure Model Y is in Park.2.
Chock the tires or make sure Model Y is secure.
3.
Press and hold the brake pedal, then on the touchscreen, touch
Controls > Service > Towing. The
touchscreen displays a message reminding you how
to properly transport
Model Y.
4.
Press and hold the Transport Mode button until it
turns blue.
Model Y is now free-rolling and can slowly
be rolled (no faster than walking speed) or winched.
To cancel Transport Mode, shift Model Y into Park.
NOTE: If your vehicle is equipped with a lead-acid low
voltage battery (see
Jump Starting on page 227):
Transport Mode may cancel if
Model Y loses low voltage
power after Transport Mode is enabled.
CAUTION: If the electrical system is not working,
and you therefore cannot use the touchscreen to
activate Transport Mode, use self-loading dollies or
tire skates. Before doing so, always check the
manufacturer
2.
Release the rear tow eye cover by pressing firmly on
its top right perimeter until it pivots inward, then
gently pulling the raised section toward you.
NOTE: Vehicles equipped with a hitch receiver cannot
be pulled from the rear tow eye. Use the tow bar or
hitch receiver only to pull the vehicle to a safe
location, such as onto a
flatbed truck. Do not
transport the vehicle with wheels on the ground.
3.
Fully insert the tow eye into the opening, then turn it
counter-clockwise until securely fastened.
4.
Attach the winch cable to the tow eye.
CAUTION: Before pulling, make sure the tow
eye is securely tightened.
5.
Activate Transport Mode.
6.
Pull Model Y slowly onto the flatbed truck.
Secure the Tires

Rear tire tread depth low - Schedule service
Inspect tires for rotation/replacement
What this alert means:
NOTE: This alert does NOT indicate that there is a flat tire.
Your vehicle has detected that the rear tires have experienced more wear over time than the front tires, exceeding the recommended
difference.
What to do:
It is recommended that the tread depth on all tires be inspected. As your tires wear during normal driving, the rear tires generally wear more quickly than the front tires.
Tire rotation is important to balance tire wear evenly across all tires. 3When staggered tires (different front and rear
tire sizes) are installed, regularly rotating the front and rear tires between the left and right sides of your vehicle will
still make your tires wear more evenly and extend their life.
Failure to rotate tires as recommended poses a risk of hydroplaning and losing control of the vehicle on wet roads.
Failure to rotate tires also decreases the life of your tires, requiring premature replacement.
It is recommended that you schedule service via your Tesla Mobile App or with an independent service provider to
have your tires rotated when:
The alert will clear once the Tire Pressure Monitoring System detects that each of your tires is inflated to the
recommended cold pressure.
