Seeing those snowy pics made me think that I'd better double-check that I do have everything I'll need for my winter commute. I noticed that my Schwalbe Marathon Winters were still covered in last season's grime, so I got out the ArmorAll and gave them a quick wipe-down. You can see under the Schwalbe logo how much brighter the reflective strip is, but the dirty side shows that even when grimy the strip still reflects light. IMO a good feature on a winter tire.
