The spec from the MT site shows the 12" section width based on a 9.5" rim, so if the theory holds right that every 1/2" rim change equals 2/10 section change, then the 295/55 should come in with a section width of 12.2" on a 10" wheel. This is the part I am needing to confirm, as that is nearly exactly what I have to fit a tire. I am at the point I need the tire now to use to cut the rearend and I just didn't want to order a set and find out that it would not fit. Mr. P, that is why your measurements were of interest to me.

Thanks for the help.
