Got my bags on today. Got my tire pressure dialed in for daily driving, running the 285/70/19.5 Michelin XDS 2's at 85 psi, they run smooth. Haven't loaded up my TC yet, but I figure they will be take...
I run 0-10psi in my airbags when unloaded (they have internal bumpstops, so manufacturer says it's ok to run with no air) and 65psi with my camper loaded (Wolf Creek 850). Truck is a 2002 F-250. The truck sits level and rides well at that pressure, but it also has an add-a-leaf that's part of the 4" lift kit.
