Wow, like those folks above, I would never use a slick or even lightly knobbed ti(y)re. I have a SS drop bar MTN bike with Kenda Nevegals on them. I was actually looking for something that wasn't going to break the bank albeit would have enough grip for the same situation(s) you describe above. I love these buggers. Not sluggish at all and roll very well for being 2.35's. Been really happy with them.
