I've recently had my birthday, and have been offered a pair of studded tires as a gift. The bike I'm intending to mount them on is an old mountain bike set up for city riding, so I'm looking for thinner, mildly-treaded 26" tires with carbide studs. However, no one seems to have such tires in stock other than Peter White offering Marathon Winters for an uncompetitive price. Is it simply too late in the winter for me to get a pair? I'm around Pittsburgh, in case anyone happens to know anything locally.
