Too soft

Going too soft yes will wear you're tires. On a ton I'd think you're door jam would say to run you're duals about 65 psi? Or does it say higher.

I wrote BF Goodrich and they sent me an inflation chart but it has no mention of light or heavy loads and it also doesn't even show a dually application.
When I talked to a Ford rep, they said go with what's on the doorpost. So the truck rides like a one-ton truck (go figure) but when I wear the tires prematurely, I've got all the documentation that says I maintained pressures as recommended.

Ford is going to recommend using their door jamb pressures because they have to play it safe and assume everyone is the average uninformed motorist. It's much better to have too much air in the tire and a rough ride unloaded than to load up a pickup bed with gravel on underinflated tires that will blow out going down the freeway. So you can't go wrong with the door jamb pressures if you don't mind a rough ride. If, however, you want a smoother ride and are willing and able to remember to adjust pressure for new loads, then going with a lower pressure is perfectly acceptable and safe.

Here's a great tire info sheet from Firestone:
