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

There is, of course, the old-fashioned "chalk test".
Go to a large parking lot, make a chalk mark across the tread of the tire. Drive a few feet, then look at the mark.
If it is worn off mostly in the center, the tire is over-inflated.
If it is worn off mostly at the edges, the tire is under-inflated.
If the mark is evenly worn, the inflation is just right.
Same principle, but I use masking tape across the tread instead of chalk. I'll check it after driving a few miles and adjust the pressure until the wear pattern is slightly biased to the middle.
I kep trailer tires at maximum sidewall inflation pressure to minimize heat. In my experience, trailer tires are always replaced before the tread wears out anyway.
Well are you running ST's on your trailer that might be true, but with LT's that are rated to carry 3,042# ea. and the total weight on the 5er tires is only 9,000#. I run my trailer tires at 70 psi, because full contact equals better braking.
