Wheels and tires
Note: If tire wear is uneven (on one side of the
tire only) or becomes abnormally excessive,
the wheel alignment should be checked.
Age degradation
Tires degrade over time due to the effects of
ultraviolet light, extreme temperatures, high
loads, and environmental conditions. It is
recommended that tires are replaced every
six years, or sooner if required.
Punctured tires
Your vehicle is fitted with tubeless tires,
which may not leak when penetrated,
provided the object remains in the tire.
If, however, you feel a sudden vibration or ride
disturbance while driving, reduce your speed
and when safe to do so, stop and check for
the cause of the vibration.
A puncture will eventually cause the tire to
lose pressure, which is why frequent checking
of tire pressures is important. Punctured or
damaged tires must be permanently repaired
or replaced as soon as possible.

Directional tires
WARNING: Road holding will be
seriously impaired if directional tires
are incorrectly installed.
Your vehicle is fitted with directional tires. An
arrow on the tire wall shows the direction of
rotation. These tires must be fitted to rotate
in the direction of the arrow when the vehicle
is moving forward.
For this reason, tires must not be swapped
from one side of the vehicle to the other, and
replacements must be fitted with regard for
axle/wheel rotation.
Replacement wheels and tires
WARNING: For your safety, it is
recommended that only wheels and
tires that match the original specification are
used on the vehicle.
Wheel rims and tires are matched to suit
handling characteristics of the vehicle.
Always check that replacement tires comply
with the original specification. If tires other
than those specified are used, ensure that the
load and speed ratings (shown on the tire
side wall) equal or exceed those of the
original specification.
For the specification of the original wheels
and tires installed on the vehicle, refer to
Specifications and tire pressures, page
Note: Different sizes are specified for front
and rear tires. Therefore, wheels must not be
swapped from front to rear or vice versa.
Winter tires and chains
WARNING: For your safety, it is
recommended that if winter tires or
chains are needed, you use only those that
are recommended by Tesla Motors.
Tesla recommends the following winter tires
and tire pressure settings:
• Front: Pirelli 210 Snowsport 195/50/R16
84H at 25 PSI (172 kPa)
• Rear: Pirelli 240 Snowsport 215/45/R17
91H at 36 PSI (248 KPa)
If snow chains are necessary, Tesla
recommends PEWAG Neon x3 Montage.
