I tend to go through alot of tires in the course of a season(multiple bikes). I have found that I have had very good luck with Maxxis and Schwalbe tires. In the Maxxis line, I ride the Courchevals and love them!! I also sell alot of the Detonator model in the shop. In the Schwalbe line, I'll sell a lot of different models... anything from the Lugano to the Ultremos that I ride. At any rate, any of the above are a good choice, it simply depends on what type of tire you want to ride and of course how much you want to spend.
