Like many , I switched to the 160/60-17 on the Sport (from 170/60-17). Next tire I think I'll go to the 160/70 just to get a little more weight to the front.
Sure interested in how many miles you guys are gettinr out of the Diablos. And , like the Pirelli Dragon, are there "corse" as well as other cmpounds of Diablo?
