RAM 3500 dually that will soon have a TC on it. It's a question of what should the rear tire pressure be and I'm wondering what you run your dually at. The camper should be around 4-5k pounds. I'm ...

I have a second spin on this. She bought the truck new and the tires are stock. I believe that they might run the tires at a lower pressure when it is new to help the the ride feel smoother as a selling point. Now if you are going to seriously use the truck for heavy hauling and you actually need those high pressures to carry loads, you would go and have the dealer air it up and readjust the TPMS alarms high and low points. Now I don't know about whether or not you as the user can do it, but I don't know because I didn't go through the manual. Does anyone know if it is a user adjustment or special software only the dealer has? I will touch on it when I see her again in September.
It's never been user adjustable without aftermarket programmer. And since around 2016 it's not dealer adjustable anymore. The nhtsa locked the dealers out of their own software basically.
You can re-adjust thresholds with aftermarket stuff like Autel ?? Programmer.
But I've never seen the high end adjusted down. Only low end adjusted down. Every 2014-2016 Ram 250 I've been around, the low is 65 and no alarm for high.
I reprogrammed a bunch of them with Chrysler Witech software but don't remember if you could change the upper threshold.
