This is the best rolling resistance for this tire size (I know because i've been searching for the same size) Now its just a matter of saving 250 in order to buy them and test them a little
.
O and the place i found the chart for this tire was on this site, just search for
"LRR (low rolling resistance) tires - Green Seal report & list" Its somewhere in that thread.
I would put a link but i gotta hit 5 posts before I can.
