Most folks understand ply sheer stress with tires on trailer with close spaced axles.
And most folks can read all the website info on why max sidewall pressures work best for tires on a trailer.
And most folks understand those load pressure charts are a minimum pressure for that load only with no reserve that hi scrub tires on a trailer needs unlike low scrub tires on the tow vehicle.
For those that don't understand the need and reasons for higher pressures on any tire on a trailer should spend some time on Tireman9 rvtiresafety.net website. You get input from a actual tire engineer who understands why max pressures are recommended. Its suggested reading for those interested in knowing the howz and whyz. http://www.rvtiresafety.net/2019/07/why-inflate-motorhome-tires-differently.html
This clicky is one on several Tireman9 has on the subject on pressures for tires on a trailer. Lots of reading.
Even with all that you are saying, and I agree, it just doesn't make sense to follow these inflation charts on the bigger heavier fifth wheels, and I doubt there are any that do, other then the one individual. I don't run 110 on mine ,but I don't run 70 either . I know many in my weight range run around 100 on the Sailun G rated . And many that run the 110 .
