Considering upgrading from 16' to 17.5" WWYD?
But the cost is pretty significant. Here's the background: We have a Heartland Cyclone 3010 Toy hauler. I'm not sure how much it weighs fully loaded. I'm going to guess no more than 6-7 tons? We...

The GY G614 is GY high end trailer tire. It is the same diameter as the Marathon ST235/80R16E. Rating goes for 3420 with the Marathon to 3750 with the G614. However your wheels have to be able to handle 110 inflation to use the full 3750 rating. What is the listed GAWR and GVWR on the placard on the left from corner?
There is another LRG tire in the Sailun that cost a lot less, however it is larger in diameter, so you need at least 33+ inches between the axles. Being a TH you should not have clearance issue above the tires.

Just about 99.99 percent of ST tires will perform similar to the ones you currently have. So if you what to get off that treadmill then you need to go to higher quality tires.

Chris is right on his points listed above. .I also don't understand the need for 17.5" wheels/tires on a 5th wheel with GVW of 15,500#...though he does have 7,000# rated axles.
My 5er has 7,000# axle ratings and came with the GY G614's....expensive tire, but a great tire...GVW on my 5er is 16,900#....loaded to 15,920# and a pin weight of 3340, puts 12,580 on my two axles. ( as stated by Chris, the GY G614 has a capacity of 3750# each)
We don't know that much about the Sailun, but it has some great credentials behind the manufacturer...I will look at their tire when it's time to replace my GY G614's, time will tell.
States your 5er came with E rated tires, so 80 psi rating?.... If you can't get wheels rated for 110# air pressure, I'd look at a "E" rated tire that can handle the weight on your axles. If they can take 110 psi, I'd go with a G rated tire as mentioned above.
