solo tire pressure

[Road_Phantom]

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.

[Old-Biscuit]

I have a 2007 Dodge 3500 SRW with 17" 'E' tires

I run 55# front tires ALL the time...towing or not (4850#...scaled weight/diesel)
I run 80# rear tires TOWING (6200# scaled weight)
I run 45# rear tire NOT TOWING (3260# scaled weight)
