Someone gave me a brand new set of Michelin 650c Pro Course Service Race tires.
I haven't the foggiest what to do with them? I've never had any dealing with a 650 wheel, so I wouldn't know where to start. What bikes came with these size wheels?

Actually, if anyone here has a burning desire to own a set of these, I'd glady trade them for an equal set of 700x23's.........
