Lucid Air Touring
I have a Air Touring with 245/45 R19 wheels. The sticker on the door frame specifies 49 psi for both front and rear tires.

The new software update recommends 42 psi all around. The software knows what tires are on the car.

What is the correct number? Thanks
 
Thanks! I have the same issue. I had 44 PSI in all tires but still giving me warning sign. I think I need to fill up to 49 to get rid of that. I have 19-inch wheels as well.
 
Did you check to see if the car has the correct tire size entered into the system? It sounds like the tire pressures that would go along with lower profile tires.

In my case, yes, the correct tires are in the system.

I suggest changing the setting to an incorrect size, then back to the correct size... sometimes a knob like this can get its externalized value out of synch with the/a value used internally.
 
I’ve been having the same issue (Lucid AT with R19 aero wheels). I got alerts that my tires were low (43-44 psi) and then in the car it says recommended pressure is 42PSI but the door says 49PSI.

tires/wheels are set correctly in settings, I even tried changing it to another tire size and back to see if it fixed it but the software takes like 2 minutes to “process” and then throws this error:
