Displaying Tire Pressures
Tire pressures display on the touchscreen in the cards area
on the car status display, or by touching Controls > Service.
The pressure of each tire displays in the visualization of your
Model Y, in addition to what time your tire pressures were
last measured. The touchscreen also displays your vehicle's
recommended cold tire pressures so you can easily
determine how much to inflate your tires. You can choose
whether you want to display tire pressures using Bar or PSI
by touching Controls > Display > Tire Pressure.
You can also view tire pressures in the Tesla mobile app.
NOTE: You may need to drive briefly before the visualization
displays the tire pressure values.
Maintaining Tire Pressures
Keep tires inflated to the pressures shown on the Tire and
Loading Information label, even if it differs 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 door is open.
If you are towing a trailer, do not use the tire pressures
printed on the Tire
and Loading Information Label. Instead,
refer to the tire pressures published in the towing section
(see Towing and Accessories on page 94).
The Tire Pressure indicator light on the
touchscreen alerts you if one or more tires is
under-inflated.
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 km/h for
a short amount of time 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 Y, a fault with the TPMS is detected (see
TPMS Malfunction on page 177). Use your mobile app to
schedule a Service appointment.
NOTE: Your vehicle’s tire pressures will drop in cold ambient
temperatures. If the TPMS indicator light appears, inflate the
tires before driving. The tires will lose approximately one PSI
for every
6° C drop in outside temperature. Proper tire
pressures help protect tires from potholes and improve range
when properly inflated.
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, resulting in unexpected loss of vehicle control
and increased risk of injury. Under-inflation also
reduces the vehicle's range and tire tread life.
WARNING: The Low Tire Pressure indicator light alerts
you only in situations when a tire is below the
recommended threshold (as indicated on the Tire and
Loading Information label) under normal driving
conditions. It does not alert you when a tire is under-
inflated based on the load you are carrying.
WARNING: Check tire pressures using an accurate
pressure gauge when tires are cold. It takes only about
1.6 km 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.
Checking and Adjusting Tire Pressures
Follow these steps when tires are cold and Model Y has been
stationary for over three hours:
1.
Refer to the Tire and Loading Information label located on
the driver’s center door pillar for the target tire pressure.
2.
Remove the valve cap.
3.
Firmly press an accurate tire pressure gauge onto the
valve to measure pressure.
4.
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.
5.
Re-check pressure using the accurate tire gauge.
6.
Repeat steps 3 and 4 as necessary until the tire pressure
is correct.
