On my mountain bike made commuter I run Specialized Crossroad on the rear. Has lugs on the edge but smooth locked tread in the center and rated 85psi (maybe 75 too lazy to go out and look). On the front I run a Specialized Hemisphere. Good on pavement as long as you dont get laid way over onto the lugged sides. good on wet roads. Good combo on hard pack dirt and even soft dirt.

Brings the suck in the mud though LOL
