Maintaining Tire Pressures
Keep tires inflated to the pressures shown on
the Tire and Loading Information label, even if
it diers from the pressure printed on the tire
itself. The Tire and Loading Information label is
located on the center door pillar and is visible
when the driver’s door is open.
The Tire Pressure indicator light on
the instrument panel alerts you if
one or more tires is under- or over-
inflated.
The Tire Pressure indicator light does not
immediately turn o when you adjust tire
pressure. After
inflating the tire to the
recommended pressure, you must drive over
25 km/h for more than 10 minutes to activate
the Tire Pressure Monitoring System (TPMS),
which turns
o the Tire Pressure indicator
light.
If the indicator light flashes for one minute
whenever you power on Model S, a fault with
the TPMS is detected (see TPMS Malfunction
on page 152).
On newer vehicles, you can display tire
pressures on the instrument panel by
choosing to display Car Status using the right
or left steering wheel buttons (see Using Left
Steering Wheel Buttons on page 41 or Using
Right Steering Wheel Buttons on page 42).
You can also choose whether you want to
display tire pressures using BAR or PSI by
touching Controls > Settings > Language &
Units > Tire Pressure.
Checking and Adjusting Tire Pressures
Follow these steps when tires are cold and
Model S has been stationary for over three
hours:
1. Remove the valve cap.
2. Firmly press an accurate tire pressure
gauge onto the valve to measure pressure.
3. If required, add or remove air to reach the
recommended pressure.
Note: You can release air by pressing the
metal stem in the center of the valve.
4. Re-check pressure using the tire gauge.
5. Repeat steps 3 and 4 as necessary until
the tire pressure is correct.
6. Replace the valve cap to prevent dirt from
entering. Periodically check the valve for
damage and leaks.
Warning: Under-inflation is the most
common cause of tire failures and can
cause a tire to overheat, resulting in
severe tire cracking, tread separation, or
blowout, which causes unexpected loss of
vehicle control and increased risk of
injury. Under-inflation also reduces the
vehicle's range and tire tread life.
Warning: Check tire pressures using an
accurate pressure gauge when tires are
cold. It takes only about 1.6 kms of driving
to warm up the tires suciently to aect
tire pressures. Parking the vehicle in
direct sunlight or in hot weather can also
aect tire pressures. If you must check
warm tires, expect increased pressures.
Do not let air out of warm tires in an
attempt to match recommended cold tire
pressures. A hot tire at or below the
recommended cold tire
inflation pressure
is dangerously
under-inflated.
Warning: Do not use any tire sealant
other than the type provided in a Tesla
tire repair kit. Other types can cause tire
pressure sensors to malfunction. If your
Model S did not include a tire repair kit,
you can purchase one from Tesla.
