They're awesome on dry pavement. Deathwish on wet roads. Trust me...
Unless you're really going to be needing to go for 5+ PSI launches, I'd HIGHLY recommend BFG Drag Radials. They ride beautifully, and can handle moderate street launches. I've had 2 or 3 sets of both tires on the street, and I'll never use the M/T's again [on the street]. The flimsy sidewalls make for a crappy, wavey ride.
