Supremes. Love them. I do have pluses on a fixed-gear commuter. D*** I wish I could wear those things out so I could replace them. Ultra tough, ultra heavy, pretty hard to mount and they feel deader than any tire I've ever ridden. They just don't feel lively at all, and they don't corner very well either.

I'll mount regular Marathons on the fixie because I only want to shell out the green for the Supremes for my "good" bike.
