According to, the Ecopias I got are 24.5" in diameter, the same as what I measured on the 17's (17's were much lower profile). They have 10/32 of tread, meaning that when both sides are considered, there is 20/32 of tread, or over half an inch. I am going to go ahead and say that the 2% difference that may exist is negligible in this case, especially since we are talking a 20% difference in FE (not 2% or 5%). I will measure actual circumferences and report back, but don't expect anything earth shattering.
