I have Continental Town and Country on my 26" folding commuter. 2.1" Nice and big, not too heavy, and they were a step up in terms of grip, comfort, and ride feel from the old Kwests that were on the bike when I got it. (the kwests were pretty worn and dried out, so it might not be the fairest comparison.)
