Sailun specs say 6.5". The dealer told me that 6.5" was optimal but the tire can be mounted .5" either way with no problems. The only thing left is to find the PSI stamp on the wheels. So far, I have not found it. There is a bunch of other stamps like Max load 3040lbs but no max PSI.

If it has 3040 max load, very much doubt they are rated for 110 psi. Sounds like 80 psi wheels.
As far as price, thats a terrible price quote from Big O. I was quoted 635.00 for a set of four, five would have been about 793.00. Thats here in the Salt Lake area.
It looks like you are headed for new wheels if you want to with a G rated tire.
Most wheels on these fifth wheels are 6", and are okay with the G rated tire .
If you have to go with new wheels, then get the 6.5 . If your present wheels were rated for 110 psi, they most likely would be rated for 3750, not 3040. Many put G rated tires on their OEM wheels rated for 110 psi that are the 6" wheel, I am one that does. I am on my second set of G rated tires on my OEM 6" wheels.
