I just got a new bike and have begun cycling in the belly of the beast - a Northwest winter. It just started snowing, and has iced over slightly today. I bought a 2008 Specialized Globe Centrum Sport (single speed), added fenders and crank brothers Mallet "C" pedals. The guy at my local LBS didn't recommend studded tires, however; I'm running Specialized Pro MTB tires. Maybe you guys might have some insight as to running mtb tires in winter, over textured ice, frosty roads, and snow. I only slipped once - I had fun in the powder, though - and want to hear some insight as to whether mtb tires are the right stuff for snowy and icy unsalted roads. It's been fun, somewhat challenging, and I've never commuted to work before, nor have I owned a single speed (with the exception of my childhood mongoose bike.) I have a padded motorcycle jacket from my motorcycle - would you recommend riding with that in case of slipping? I may look goofy, but I know I'd be okay if I busted...
