More often than not its in the rim. My 35" MT-Rs went from 34" on 8" rims to a damn short 33"ish on 10" rims. Thats why I asked, because Mr. Glen here is on 10s. While a friend of mine, at 25psi and 12" rims they measure a little shorter than these here.
now, if its not to much trouble, could you get us a width measure ment looking at the tread(so we can see section width vs. tread width) please?
