TPMS low tire pressure warning

[Merrill]

Can someone tell me at what tire pressure will the TPMS give you a warning that a tire is low. I have set my tire pressures to 42psi and went out today to check them and they were all at 35. I thought that once any tire got 5psi below the required setting the warning would show on the dash.

It's 35 or 36. Then won't turn off again until you get to 37 or 38 for at least a few minutes. Sorry I can't remember the exact number. I had a nail in my tire causing a 1-2psi per day drain, until I could get the tire replaced (unfortunately neither Tesla nor the local tire shop could repair it).

I've seen warnings at 36 & 37, never higher, and they don't go away, staying on your cluster screen when car is ON. After filling, OK

If you accurately measure 35psi, there may be an offset to look into.
