I really like to have a tire for the conditions, but for just all around riding I like the Specialized Roll-X in the rear and a Continental Survival Pro up front. There are actually a lot of tires that work allright for me in the rear, but in the front I haven't found anything that is even close to the Conti Survival Pro for handling, traction, and rolling resistance at such a light weight, this is the 2.3 version I'm referring to.
