PR2 Diablo Strada's Roadsmarts BT021 All gonna get you 8-12K, I've only ran the Strada's and I love them. Two other members I know have the Roadsmarts and are very happy with them. My father has a set of PR2's and has been very satisfied. I've ran PP's and BT016s and got about 4K before they were flat spotted to the cords in the middle, edges still had a ton of life though... IMAO having a sport tire (PP, Diablo Corsa, Qualifer, BT016) isn't worth the money for street use. A smart rider isn't going to use them to their full potential. You're gonna flat spot that tire if you do any type of commuting. Even any of the 2ct sport tires are still soft in the middle and super soft on the edge, their gonna wear quick on the street. They are in the sport/race category for a reason. Hell yeah. Talk to NinjaNick, xtremef4i, myself, magley? I think...All have sport touring all rail the bikes all have no worries about traction all getting 8-10K.
