This is the size tire I have on now so I would guess I would go with this same tire: S5541960 ST235/80R16* 129/125 L 14 10 6.50 30.8 9.3 14.7 4,080 3,640 110
But what does it mean by "requires special high load capacity wheel???
Also the current goodyear marathons that came on the fifth wheel have a PSI of 80 these say 110? Does this make a difference???

I am pretty sure your wheels are rated for 110 psi. I wouldn't mess with any G rated tires other then Sailuns, they been out now for several years, with great reviews.
Check your wheels on the backside, pretty sure you will see the 110 psi rating. Simpletire online is probably your best buy, and free shipping.I bought mine locally ,and got a price match from them. So out the door was the same as Simpletire, and then paying to have them mounted ,and balanced at some tire dealer .
