rear tire pressure with 37s

posted this in the tire section but figured i may get a few more looks here.
so i have an 06 dually with a 7" icon lift and some 37" bfg km2s on 17s. i know tire pressure has alot to do with how a truck rides and its comfort. im trying to get the rear of my truck to be a little smoother. i have icon 5" plush ride leafs and icon 2.5" shocks. only thing left to play with is the tire pressure. so the bfg has a max pressure of 50psi, this is what i run in the fronts. so what would be a good pressure to run in the rear? i see on srw trucks the rear is usually lower than the front. and one would assume with two tires it doesnt need to be as high as a srw truck either. i usually run 30 unloaded. is 20-25 too low? any insight? thanks
edit: all this info is without towing
