Tires and WheelsMaintaining Tire Pressures
Keep tires inflated to the pressures shown on
the Tire and Loading Information label located
on the driver’s door pillar (even if it differs from
the pressure printed on the tire itself).
The Tire Pressure indicator light does not
immediately turn off when you adjust tire
pressure. After inflating the tire to the
recommended pressure, you must drive over 25
mph (40 km/h) for more than 10 minutes to
activate the Tire Pressure Monitoring System
(TPMS), which turns off the Tire Pressure
indicator light.
If the indicator light flashes for one minute
whenever you power on Model S, a fault with
the Tire Pressure Monitoring System (TPMS) is
detected (see page 21).
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 air to reach the
recommended pressure.
4. Recheck pressure by removing and
reattaching the tire gauge.
5. If you added too much air, release air by
pressing the metal stem in the center of the
valve.
6. Recheck the pressure with the tire gauge
and adjust if necessary.
7. 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. It 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 Battery range and tire tread life.
WARNING: Check tire pressures using an
accurate pressure gauge when tires are
cold. It takes only one mile of driving to warm
up the tires sufficiently to affect tire pressures.
Parking the vehicle in direct sunlight or in hot
weather can also affect 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 Motors.
Inspecting and Maintaining Tires
Regularly inspect the tread and side walls for
any sign of distortion (bulges), cuts or wear.
WARNING: Do not drive Model S if a tire
is damaged, excessively worn, or inflated
to an incorrect pressure. Check tires regularly
for wear, and ensure there are no cuts, bulges or
exposure of the ply/cord structure.
The Tire Pressure indicator light on
the instrument panel alerts you if
one or more tires is under- or
over-inflated.
