I'm new to rving but have pulled many gooseneck stock trailers over the years and have had better luck with larger diameter tires. The original tires are 205/75R14C with load C. Although I'm not loaded anywhere near maximum payload weight, it seems possible to overload the tires before reaching payload capacity. Thanks for you input on this matter.
Fourteen inch wheels on an RV was a "dumb" act by the manufacturer. Little choice in brand/type/size tire plus they tend to run hot. But who looks at that when they buy their new dream
The best bet is the 16" as you will have a better selection of tires - of which my choice is an LT, but there are many discussions about that here to go into that.
Without knowing the bolt pattern, it's difficult to say which wheels can be used on your TT depending on wheel lug spacing. There are several sizes in the 5 lug arrangement. A 16 inch 5 lug wheel may be difficult to find, but not impossible - but then you also need the lug spacing as well.
There are really only two more considerations after that then - overall tire diameter should be about the same as what you have on there now, unless you have lots of clearance. Added clearance can be gotten with heavier/re-arched springs or, better an over/under axle kit. Then there is wheel backspace (offset) to consider for a couple of reasons - side wall clearance and wheel bearing loads, especially if you have Never-Lub axles. The new wheels should be approximately the same backspace as the original
