I think I'm done with the Diablo Strada sport touring tire from Pirelli. I love the feel and the feedback of these things. They transition from straight-away to sweeping turn effortlessly and feel stable at all speeds. The problem is that these things seem to provide no indication of how much life they have left. They continue to feel brand new until the belts start to show through. For the second time this year I've arrived in Las Vegas with a smoked rear tire. The first time caught me off guard so I kept an extra close eye on the last Diablo that I had. The day of my departure for LV I looked both tires over thoroughly and even had the owner of Desert Cycle Works take a good look. We both agreed that I could get 500 "hard miles" out it with some room to spare. Not the case at all. 185 miles later the center was starting to peel away. I babied it home a couple of days later (at the posted speed limit...yuck) and had DCW put a new tire on. That Pirelli was on the bike for a total of 5050 miles. This time I went with DCW's last remaining Avon Azaro (AV46). Avon stopped making the Azaro model that I liked so much, but DCW made me a smokin' deal on the last one. So for now, I'm an Avon guy again. Maybe I'll try Avon's new Storm model next time. Who knows?
