I commute daily on an mup that rarely gets plowed but does get salted. Problem with that is unless they salt before I leave in the a.m. (rarely) it's 10 miles of frozen ruts. I run Nokkian w106's this time of year but the ruts scare the crap outta me. I'm enamored with fat tire bikes but really don't have the money or space for another bike. Any suggestions?
