What Tire Pressure do you usually run in your fifth wheel tires?

Max as listed on the sidewalks. Anything less, especially with an ST tire and your load rating is reduced.

Gonna get a lot of replies. We always have and always will use the max pressure shown on tire sidewall. Had flats (nails, screws, wire)and the infamous Duro tires but no blowouts on a popup and 4 different 5th wheels over 40+ years.

Max on the sidewall. Trailers are usually loaded to the maximum capacity of the tires or more.

???? Depends on the tire and the tire size. Run the PSI indicated on the sidewall for all tires.

Weigh the fiver then consult a weight chart for your tire brand and size to get the CORRECT pressure. Several problems can occur when running higher than needed pressures, not the least being increased susceptibility to road hazard damage, another being a rougher ride than necessary for your fiver.

I have towed over 60k miles with all eight tires on the 18k lb. fiver (yes, twin axle dually) set at 65 PSI cold. One leaker due to picking up a nail, never a problem on the road. The Pressure Pro makes it real easy to monitor the pressures.

Completely agree with the above. Only if you're able to weigh each trailer wheel or as a minimum, each axle, would you consider inflating less than the maximum allowed tire inflation pressure or what is written on the trailer's certification label. You don't want to experience the results of under inflation pressure.

Max is good, although I sometimes like to run about 5psi below max. But that depends on whether I am near the max load rating. There is no reason that I can think of to run below the max. The tires run coolest when inflated to the max.
