I have done a search and read a lot about different ones. I am looking for something with the durability of the armadillo (They have proven to be outstanding on my road bike) but I want some tread for when I hit the dirt trails coming home.... Is there such a tire? Seems I can find slicks with durability, knobies with durabbilty but not a good mix version. Whay I am doing is a mix of concrete/asphalt and I like to sneak in a path once in awhile on the way home. nothing major as far as technical is concerned. Just a few rocks and roots and mostly hard packed dirt.
