WARNING: Forward Collision Warning and
Automatic Emergency Braking (if equipped) do
not operate when driving at very low speeds (see
Collision Avoidance Assist on page 117). Do not
rely on these features to warn you, or to prevent or
reduce the impact of a collision.
NOTE: Your chosen setting is retained in your Driver
Profile until you manually change it.
Parking Brake
To engage the parking brake, touch Controls > Safety &
Security > Parking Brake. Follow the onscreen
instructions.
You can also engage the parking brake by
pressing and holding the button on the end of the drive
stalk while in Park.
NOTE: The parking brake operates on the rear wheels
only, and is independent of the pedal-operated brake
system.
WARNING: In snowy or icy conditions the rear
wheels may not have sufficient traction to prevent
Model Y from sliding down a slope, particularly if
not using winter tires. Avoid parking on hills in
snowy or icy conditions. You are always
responsible for parking safely.
WARNING: Your Model Y may display an alert if
the road is too steep to safely park on, or if the
parking brakes are not properly engaged. These
alerts are for guidance purposes only and are not a
substitute for the driver

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 Y 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.
If Model Y comes with staggered wheels, tires cannot be rotated, as tires are asymmetrical and front tires are a
different size from rear tires.
Unbalanced wheels (sometimes noticeable as vibration through the
steering wheel) 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
Page 170 of 250

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-
inflated (see Automatic Reset of TPMS Sensors on page
169).
For the specification of the original wheels and tires
installed on
Model Y, see Wheels and Tires on page 189.
NOTE: Installing winter tires with aggressive compound
and tread design may result in temporarily-reduced regenerative braking power. However, your vehicle is
designed to continuously recalibrate itself, and after changing tires it will increasingly restore regenerative
braking power after some moderate-torque straight-line accelerations. For most drivers this occurs after a short period of normal driving, but drivers who normally accelerate lightly may need to use slightly harder accelerations while the recalibration is in progress.
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

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
