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 192
) equal or
exceed those of the original specification.
For the specification of the original wheels and tires
installed on Model Y, see
.
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
).
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's tires. The speed rating is shown on the
sidewall of your tires (see
).
Asymmetric Tires
Model Y tires are asymmetric and must be mounted on
the wheel with the correct sidewall facing outward. The
sidewall of the tire is marked with the word OUTSIDE.
When new tires are installed, make sure that the tires are
correctly mounted on the wheels.
WARNING:
Road holding is seriously impaired if
the tires are incorrectly installed on the wheels.
Removing and Installing Aero Covers
If your Model Y is equipped with aero covers, you must
remove them to access the lug nuts.
To remove an aero cover:
1. Grasp the aero cover firmly with both hands.
2. Pull the aero cover toward you to release the
retaining clips.
To install an aero cover:
1. Align the aero cover into position so that the notch at
the base of the Tesla "T" is aligned with the tire's
valve stem.
2. Push firmly around the perimeter of the aero cover
until it fully snaps into place.
CAUTION:
To prevent the aero cover from
falling off, ensure that it is fully secured before
driving.
Removing and Installing Lug Nut Covers
If your Model Y is equipped with lug nut covers, you
must remove them to access the lug nuts.
