I went from stock 255/75/17 KM's to 285/70/17 KM2's and the size difference in terms of height is maybe 1/2" to 3/4" at most (my speedo was only off by about 1.5-2 kph at 100 kph), so I'm going to say they're closer to 32.75".

I have 285/70/17 KM2s and they measure just a little over 32" when mounted and on the Jeep. The spare measures closer to 33". Still like them though!

They're not much bigger in terms of height, but they are about 1.5" wider than the stock 255 KM's and they give the Jeep a much more appropriate look

Not mine. Just to be sure I just went out and measured the spare tyre on the back. Just a tad over 33 inches on my 255/85/16 BFG KM2s.
