I just bought those tires and wheels for my Dodge. Running 40 rear and 50 front, good ride quality empty.
Warning you will have to get your TPMS threshold reprogrammed in order to run lower pressure without the idiot light coming on. It will come on a little below 70 for the rears.

Do you have a 2500? From what I've read it seems the 2500 has TPMS and the 3500 has TPIS and doesn't warn you. I guess I'll find out as I just set my rears to 50.

I have an early 07, so no pressure monitoring. Just bought the new takeoff wheels.
I did have a fleet of '14-15 Ram diesels in AK for the last yr though and the new trucks do not have the light load setting like the older 6.7s.
With the huge temperature swings it was not uncommon to see the low pressure light on at -40deg and then have it turn off after driving or warmer temps.
My work truck was a '14 2500 and I was able to program the threshold pressure down with the Witech dealer diag software I had. Pretty sure the 3500s were the same, remember seeing a lot of tire lights and most of the trucks were 3500s
