Ram2500 6.4 tire pressure

I thought there was a switch so you could set low pressure for non heavy?

Isn't there a button on the dash or somewhere on the EVIC to set 'Light' tire pressure? Not sure what Ram does on the newer trucks but my 2012 Ram 2500 has a 'Light' tire pressure button on the dash. I have to get down to 50psi on the rears for it to go to light. Or close to that anyway.

The button went away.

If its like GM you'll have to take it to a dealer to have re-programmed. I had the same problem after going to larger/wider 305 tires that don't "need" quite the PSI the stock skinnies do. I run them at 50PSI empty and would set off the TPMS warning. Dealer reprogrammed the trip point so no longer a problem. I have heard some dealers wont touch it due to liability concerns but my dealer had no issue doing it.

Yeah it's a little annoying. You can actually run the rear tires down to about 70 and the fronts down to about 60 and the lights won't trigger, but you can't go lower than that. Unloaded I wouldn't mind running mine at 65 all around but I don't really like looking at the light, so I run them a little higher - 65 up front and a little over 70 out back.

There is a fix over on the Cummins board, but you have to take it into the dealer. If you want to do that I'd print off the instructions from the very long thread discussing this matter (can't miss it), and then have the dealer reprogram the trigger levels. I need to get mine in for that ORC recall anyway so I'll probably have them reset the TPMS for me while I'm there.
