Tom, that's an interesting question. I wasn't aware that different bores were available, so I went into the garage to make a measurement. The mike clicked in at 3.17", so I'm guessing that 3.19 is the right answer.
I also observed that the bore on my wheels is bigger than it has to be, by about 1/4". It is not a snug fit on the spindle housing. In other words, a wheel with a 0.295" bore would have fit, too (if such a wheel existed). Given that the fit isn't critical, I can't imagine that going to a 0.330" bore (a tenth of an inch bigger) would make any difference.
I changed out my wheels a couple years ago. My experience was that in this basic size, TM uses the same wheel as most other travel trailers, boat trailers, utility trailers, car haulers, and so forth. There are advantages to standardization, and one of them is that the wheels are cheap and easy to get. In fact, many (though not all) tire dealers keep them in stock. Standard white-painted steel - complete with the little color stripe near the edge.
