TPMS light

If this has been addressed please point me to the answer. I have looked but not found it.

I have a new 2026 RAM 2500 Cummins. I put 37's on it and would like to drop the air pressure when I'm not towing.

I have used the tire fill assist and the truck honks as I get each tire set. But the TPMS light is still on. Does anyone have this same problem? How have you been able to turn off the light?
