I had a 2005 F350 DRW CC 4x4. and the door plate stated 65 psi front, and 60 psi rear. My 2006 F350 is identical to the 2005, except the 2006 is 2x4, and the door plate states 60psi front and rear. I have just assumed the difference in the front was related to the 4x4, which is about 500lbs heavier, mostly on the front axle.

I do believe we need to adjust the tire inflation as needed, up to the max tire psi/load ratings, as needed, for safely towing our gross weight loads.
