Going to get some winter tires for the bike

With the small flurry of snow last night -- and the ice on the roads over the long Thanksgiving weekend -- has made me realize that I need to finally bite the bullet and get some studded tires, since even a warm winter in Michigan will be below freezing. Therefore, I ordered some winter tires for my bike: nice studded tires to help grip the ice and packed snow. Unfortunately, one of the companies that manufactures studded 29" wide tires has stopped making them, so I'm forced to go with a much more expensive (but supposedly far superior) brand. I'll see how it goes.
