I went from the Dunlop Qualifier tires to the new Q2 series after some research and comparison to the Diablo Rosso tires. I can tell you I made the right choice. These tires seem stickier in the turns and provoke confidence in the overall ride. Wear in the center seems longer lasting as well. After 2000 miles I picked up a nail hole so I find myself buying a new rear. But make no mistake, a Dunlop Q2 is going back on my ride.
