Tire Pressure Monitoring - Tesla MODEL S Operating Manual

Tire Care and Maintenance
Warning: Road holding is seriously
impaired if the tires are incorrectly
installed on the wheels.
Wheel Configuration
If you are installing new wheels or swapping
them for different ones, update your vehicle's
wheel configuration by touching Controls >
Service > Wheel Configuration. This allows
Model S to learn the new wheels and provide
more accurate status updates on your vehicle.
Select a wheel from the drop down menu that
matches the new wheels you plan to install on
Model S. Selecting new wheels in the wheel
configuration also changes the wheels that
appear on your vehicle's avatar on the
touchscreen.
Ensure you are aware if your vehicle is
equipped with staggered wheels, meaning the
wheels are different sizes in the front and rear.
Check the front and rear tire sizes marked on
the tire sidewall to see if they match or are
different sizes. If the wheels are staggered,
take extra precaution to ensure the new
wheels you install are staggered in the same
way as the previous wheels.
Note: Changing your vehicle's wheel
configuration can impact range estimates, tire
pressure warning levels, and vehicle
visualization.
Warning: Only use Tesla-approved wheels
when installing or swapping wheels. Using
non Tesla-approved wheels can cause
serious damage. Tesla is not liable for
damage caused by using wheels not
approved by Tesla.

Tire Pressure Monitoring

Each tire should be checked monthly when
cold and inflated to the recommended
pressures that are printed on the Tire and
Loading Information label located on the
driver's door pillar (see
Pressures on page 173). If your vehicle has
tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure
label, determine the proper tire inflation
pressure for those tires.

Maintaining Tire
As an added safety feature, your vehicle has
been equipped with a TPMS that displays a
tire pressure telltale (Tire Pressure Warning)
on the instrument panel when one or more of
your tires is significantly under- or over-
inflated. Accordingly, when the Tire Pressure
indicator light displays on the instrument
panel to alert you about tire pressure, stop
and check your tires as soon as possible, and
inflate them to the proper pressure (see
Maintaining Tire Pressures
Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces range
efficiency and tire tread life, and may affect
the vehicle's handling and stopping ability.
If Model S detects a fault with the
TPMS, this indicator flashes for one
minute whenever you power on
Model S.
Note: Installing accessories that are not
approved by Tesla can interfere with the
TPMS.
Warning: The TPMS is not a substitute for
proper tire maintenance, including
manually checking tire pressures and
regularly inspecting the condition of tires.
It is the driver's responsibility to maintain
correct tire pressure, even if under- or
over-inflation has not reached the level
for the TPMS to trigger the Tire Pressure
Warning on the instrument panel.
Resetting the TPMS Sensors
After replacing one or more wheels (but not
after replacing a tire or rotating wheels), the
TPMS sensors need to be reset to ensure tire
pressure warnings are accurate.
On newer versions of Model S, the TPMS
sensors are reset automatically after driving
over 15 mph (25 km/h) for longer than 10
minutes. But for older versions, follow these
steps:
1. Inflate all tires to their recommended
pressures, as indicated on the Tire and
Loading Information label located on the
door pillar.
2. Get ready to drive for ten minutes, then
touch Controls > Service > Reset TPMS.
