Of course these are conceptual numbers.....going by rated tire size. There is no real way to tell actual difference considering load weight, tire inflation pressure, etc. But the idea is that all things being equal and in a perfect world, this thing is pretty damn close! And if anything just a good reference when changing tires to match something close.Originally posted by bigdanmcintosh@Aug 21 2003, 06:48 PM
just remember.. the unloaded and loaded diameter of your tires are different, so the best formula is to actually measure from the ground to the centerline of the axle to get the radius...
Wow I didn't realize there was another one out there already. I've seen tons of posts asking these questions and nobody's came up with one :dunno:Originally posted by langeberg@Aug 21 2003, 10:17 PM

why does the width matter? it could be 40" wide and its still turning the same number of revolutions..Originally posted by BRAVO@Aug 22 2003, 10:39 PM
its a neat program ,,,but the biggest prob,,and/or missed detail i see is,,,,,rim width,,like how a stock 14' rim is 14' by 5.5' and a hundred spoke is 13' by 7' ,,,that inch and a half makes a big difference in hight
