Go to Roger Marbel's RV Tire Safety .

Agree. ^^^ Based on his advice and experience as a tire engineer, I run our LRD tires at max sidewall pressure. I want the most reserve capacity I can get and I want the best handling possible. I check the tire pressure regularly and adjust it if elevation and/or temp. changes enough. One of the best things we have done to our TT is to add shocks - bounce is substantially reduced and handling on highway curves at speeds up to 65mph is excellent.
If lowering the psi based on load tables, I would go to a scale and get the weight on each side of a trailer to see how much it is unbalanced. You want at least 15 percent reserve load capacity and more is better.
To quote Roger Marble, he says "So the best recommendation I can give to trailer owners is to run the inflation molded on the tire sidewall." So I do and have no regrets.
This is probably a lot different for a TT than a MH. As max will definitely impact ride quality and control. If I ran my MH tires at max it would ride like it had bricks for wheels and handle like a greased pig. Still unclear if the OP has a TT or MH. Makes a big difference. I always set any trailer I had to max. There is no dependency for handling like on a steerable vehicle like a MH.
