Rim size of TM w/ 14" rims?

I'm trying to find an easier way to measure the rim size than to actually take a tire off and measure it.

I'm asking because I'm looking at the Kumho 857s - both the 195/R14 and 205/R14 only partially overlap the same rim sizes as the Marathons. I'm basically asking: Will the 195/R14s or 205/R14s fit the standard rim? Kuhmo says 5-6" width for the 195s, 5.5-6.5" width for the 205s. Marthons can go on wheels between 5.5" and 7".

I just answered my own question - stamped on the inside of the rim.

14x6JJ, 1870 lbs max. So I'm assuming this means 6".

Hey Joel, yes it is 6 inch. Several other TrailManor owners here have switched to the same tire you are asking about, using the stock wheel.

I took my first trip with the Kumho's. I'm using the 205R14 Kumho 857. It looked like they flattened out under load a bit more than the Marathons, so I ended up filling them to 65 lbs of air. (they were still flattened more than the Marathons, so I decided then that's how they are probably designed to ride). I'll probably let out some air for the next trip to soften the ride a bit.

That said, even with 65 lbs of air in it, and a rough road (I-25 north of Denver), it seemed less bouncy to the contents of my trailer than the Marathons were - no grills bouncing off the stove and such. I'm wondering if these tires, even with more air pressure, actually have a softer ride - but I don't know enough about tires to know for sure.

They are almost an identical height (slightly shorter) than the 14" Marathons, and are a bit narrower (as you would expect - a 205 vs. a 215), which is nice because the original tires were very close to the wheel well covers.

They are of course balanced and I replaced the valve stems with metal stems.

Thanks for the help on the rim size.
