General rule for tire pressure?
I know the best answer is going to be "take everything to scales and check the pressure charts"....but is there a general rule of thumb if this can't be done? Thanks

Door jamb numbers are for ride.
I would go closer to the maximum shown on sidewall. You could drop down a little but not more then 10 pounds.
Incorrect. That's a ridiculous recommendation. The tire sidewall on my F150 lists the max load pressure at 85psi. At 85 psi, each tire is rated to carry more than half of what my truck weighs. Why would I inflate them to that pressure? It would ride like it's rolling on rocks!
Inflate the tires to the load they will be carrying. The tire manufacturers don't have Load vs. Inflation Pressure tables for nothing...
The 'Rule of Thumb' is to start with the pressure on the door sticker (or the trailer's tire sticker) and adjust accordingly after verifying the weights on the tires.
