Hey Tom,
Very interesting stuff...Thanks for posting all that you do around here.

The rear tire is a 3.55-60/15 and should be about 27 tall. I measured them. 25.75.


hey Tom, if you get a chance, could you measure from the centerline of the wheel to the ground for us? I believe that taking this measurement and doubling it, gives us the most accurate/realistic diameter to calculate from. This "rolling diameter", or "effective diameter" if you will, takes into account tire deflection.
Thanks again,
