I used the Michelin Wildgripper City tires for a couple of years. I like them a lot, but with the glass laden roads I ride, the flats were frequent. Now, I have Specialized Nimbus Armadillos on the MTB and have not had a flat in the several months I have used them. I would think any 1.5" slick would be sufficient for most urban riding/commuting.
