I just replaced my old tires with 235/85 R16 Commerical TA's, but the dealer wasn't sure what pressure to inflate them to. He said most likely 75-80. My 5er is a King of the Road, Royal Villa, 36ft. What pressure should they be inflated to??
The max rating of the tire so you can carry the max rated load which you are probably close to anyway.

I agree. Also the max. pressure will also give you maximum fuel mileage & maximum stability. Tires not fully inflated heat up quicker & to higher temps & low pressure allows the potential for sway. My brother has a TT. He replaced his truck tires & the tire shop inflated the tires to a "comfortable ride" pressure. In addition, his trailer had sat over the winter & the tires were low. He came from Kentucky to Georgia to meet my wife & I. We followed him back to Ky & noticed that his rig was swaying all over the road. When we stopped for the night, we discussed the swaying. He said it had gotten worse since he replaced his truck tires. The next morning I added approx. 12 lbs of air to each truck tire to maximum pressure on tire sidewalls & did the same for the trailer using my compressor. The swaying stopped & he got an extra 25 miles on each tank of gas for the remainder of the trip.
Somewhere on your trailer, there is a data plate that gives the recommended tire size, load rating, and tire pressure, as well as the maximum GVW of the trailer.
Personally, I would use THAT recommended pressure. Yes, you can inflate to the max pressure shown on the tire, if you don't mind your tread wearing out in the center. Having tires over inflated also lessens available traction, due to the reduced footprint.
Once again, it is all about preference. I prefer for my tires to last the way they were designed to.

I don't suppose you would consider airing your tires according to the actual load you are expecting them to carry???....Brian
If you installed oversize tires then you should weigh the trailer and refer to the manufacturer's inflation table.
If it is OEM size then run the max on the sidewall.
