8Load range. Shown as Standard Load (SL) or Extra Load (XL), the load range determines how much weight
your tires can support at a
specified tire pressure. When replacing tires, only use tires of the same load range. If
towing with snow tires, ensure they are the same load range of the tires your vehicle came equipped with.
9Tire 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.10Maximum tire load. The maximum load which can be carried by the tire.11Maximum permissible inflation pressure. This pressure should not be used for normal driving.12U.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

Uniform Tire Quality Grading
The following information relates to the tire grading system developed by the National Highway Traffic Safety
Administration (NHTSA), which grades tires by tread wear, traction and temperature performance. Tires that have
deep tread, and winter tires, are exempt from these marking requirements.
Where applicable, quality grades are found on the tire

DO NOT TRANSPORT WITH
WHEELS ON THE GROUND
The rear motor in Model Y generates 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
NOTE: 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) only when Transport Mode is
enabled (see
Activate Transport Mode on page )
while the vehicle is being winched onto a
flatbed truck
or pulled out of a parking space for repositioning.
Exceeding these boundaries can lead to
significant
damage and overheating that is not covered by the
warranty.
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 ) before winching
Model Y onto a flatbed truck (see Pull Onto
Flatbed Truck From Front on page and Pull
Onto Flatbed Truck From Rear on page ). 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.
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 156). 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. The following are
required to enable Transport Mode:
