Tire Choice
I have made the decision to replace my GY Marathons (E)rated tires on my 15000 LB fiver. I am also replacing the wheels with 110PSI rated wheels. I'm leaning towards going with Sailun 637 235/80R/16. ...

You didn't say what year the 5th wheel is but many late models that came with the "E" rated ST tires also have wheels rated to mount tires up to 110 psi. Mine is a 2010 Fuzion and it came with wheels rated to 110 psi. The rating was stamped on the backside of the wheel and didn't require tire removal.
And nothing says you have to run them at the full 110 psi, but you'd be introducing a certain amount of sidewall flex if you tried running them at 80 psi. It could be done, but may be detrimental to the long life of the tires.
