Have an option to display the tire pressure (low/good/high) using the turn signal LEDs on each corner of the car when parked.
For example, when the right-front tire is low, blink only the front right turn signal slowly. If the pressure is correct, keep the light steady, and if high pressure, blink quickly.
I love the tire pressure monitors for each tire on the display but an external display avoids the need for a separate tire gauge.
We’re closing this out as the tire sensors do not work when the vehicle is stationary.
