nice article. weird how Pirelli is very good tires, but don't seem as well known or sell as well as the PP. see the vote above as example. also weird how the Metzeler line - which is owned by Pirelli and many claim is the exact same rubber - didn't rate as well. Riding the M3's myself right now, does not "feel" the same as the Diablos to me. I don't feel as safe, confident and planted on the M3's as I did my Diablos. I plan to mount the Corsa III's next [dual compound] and suspect that will be a great ride also.
I will say, that article seems to be more about track style tires than standard sport tires so there are differences to be found between those styles.
