I am guessing not but if you have a bike with large tire clearance I have been very interested in this tire, their theories make a lot of sense. http://www.conti-online.com/generato...Winter_en.html

If that is too big you can check out these guys, it comes in a 28 and is very puncture proof which is nice because flats are especially no fun in winter. http://www.conti-online.com/generato...urride_en.html

If you can not fit a 28 you are kind of stuck with what you have but like others have said, you will likely be OK as long as there is no real ice or compacted snow, just take it easy in the slush.
