"You have to replace the wheels to accommodate the higher pressure."
This man answered my question, right away, on first page. Not what I wanted to hear, but I think likely the correct answer.
My thread went off the track, turned foolish at one point. I may have hurt some feelings, trying to keep it on track. Hope not!!
I will answer CumminsV12, as to my tire edge wear from scrubbing, which is already described in my post on page one. Several of my tires show tread wear, on the edges mostly from my tight backing/severe side scrub, at home. I will not describe, but the black marks on my concrete driveway tells the story, as does my visible twisted wheels/suspension.
As to the tire inflation chart tire pressure, Capri was correct, a minimum. Using these minimum inflation charts, is not a one size fits all. They have charts for all types of tires. Truck tires, MH tires, single axle tires, not the same as an RV with tandem, or triple axles.
For FW tandems like mine, and some triples, also TTs, you can weigh your trailer, to get actual weight on tires, look at the RV specific chart. Now to find a very minimum, add 10% more air, could be 5 lbs maybe 10, but use 10%. Now that is a minimum, using 20% is better, if not going over sidewall max. Best of all, unless you have way more tire than needed, is to just inflate to sidewall max, for best protection from tire damage.
An ST tire gets it's strength from air pressure. To protect the belts, and avoid ply separation issues, from severe scrub, more air is better, all the way to max sidewall pressure, is recommended.
This post is not what my thread was about, but I feel is an important issue. If someone would start a new thread, maybe over on general, others may chime in with their thoughts.

We went thru all this back around 2009 on the Montana forum . Many of us had the new Montana fifth wheels with the china bomb tires on them . Most wanted to go to the Goodyear G614's , about the only game in town for a G rated tire back then . I had alloy wheels on my new 2008 Montana fifth wheel, that had no weight or psi rating on them , as many of the other Montana owners had . Anyway someone got with wheel manufacturer , and they sent us all a sticker with a 110 psi, and 3750 lb rating to stick on the wheels . That was all all fine ,and dandy , and so some of us went with the G614's . Well the wheel manufacturer decided to change their minds after the fact , I am sure it was a CYA after giving it some thought .
Anyway , I ran those wheels up until two years ago with G rated tires ,and 100-110 psi , no problems , as did many others . Thats my two cents worth. :)
