solo tire pressure
Since I won't be towing my 5th wheel for a few months, I'd like to improve the ride of our daily driver. How low can I go. We have a 2014 Ram 2500 2x2 Big Horn with 18 inch wheels.

I always use what gives my particular truck/car the best ride and the longest tire service. Works much better for my 2500 Dodge/Cummins than the silly door post placard that says 50 psi under the Cummins and 80 psi rear.
This truck has the LT265/70-17 E tires. I keep a front and rear axle scale ticket in all of my vehicle glove box. When empty this truck works best with 45 psi in the rear (1420 lb load per tire) and 65 psi under the Cummins (2120 lb load per tire).
Of course I air up when towing or hauling different loads. I ran the OEM Michelin LTX AS for over 112k miles using those numbers.
On my 98 RAM 2500 4x4 I would run 72 front and 45 rear unloaded. BFG's I would get over 100K and Michelins 120K. I used 3rd gen factory take offs.
BFG's in pic have just over 100K.
