hardly, 5-6% is exactly what i think it is. the calculated inflated tire diameters are only slightly less than Woody posted, so let's round it up to 6%, of itself not an impressive difference. especially since the cross section variance is a multiple of that number.

woody is correct in pointing out that there are a number of factors involved, including the unsprung weight of the wheel assembly, something i hadn't considered.

i've run plenty of miles off paved surfaces on 17, 19, and 21", so i do know a least a little about how these sizes perform in different conditions.
