I'll will run mine at 65psi(cold) and it gives me a good ride. We pull a boat with that psi also and it they handle it fine.
I just have to rmember to tell the dealership not to fill the tires to the recommended PSI.....it rides like crAAp with 80psi in the rear. I think it is 55 in the front and 80 in the rear if I remember correct.
I got some new tires the other day and when they were bringing my truck out of the stall the tires made all kinds of noise while they were turning. I asked how much air they had in them and they told me 35psi. I told them to put in 50lbs in all four. What a difference.
Work in a tire shop, if your looking for ride quality and good ride, I would put 60 or 65 in frot, and 40 in the rear. Lots of weight up front, and the rear, unless towing don't need much. Keep the wheels from spinning easy also, haha. This is what I use and never get any complaints.
I found this a couple years back and have followed it since. Tires wear evenly across and the ride is always nice. I never go below 45psi for what it's worth. The front is always between 50-60psi. 50 unloaded, 60 loaded. The back is anywhere from 45-50 unloaded and 70 psi if I'm getting firewood, 80psi with the trailer (see sig).
