Same on my Ram. Only problem with it is I get the idiot light all winter because I drop my rear tires to around 60. Suffering a quarter inch idiot light and a warning ding at startup isn't the end of the world, though.
Buy a Bluetooth OBD reader that will pair with your phone. I have OBDLINK MX, but most will work.
Buy the AlfaOBD app on your phone.
Get your 4 digit key code(the one for your key fobs) from the dealer parts/service department. You may have to show proof of ownership.
Use AlfaOBD to set the TPMS to whatever threshold you want and then reset the body control module with the key code. No more light until you reach the threshold you set it at. You can also code in some other things on your truck or any Mopar vehicle as well depending on your make/model/year.
I can PM you my personal phone number if you need help with the process.
