My wild idea is tire chains for bikes.
I think the big problem is the brakes. Unless you go to disc brakes, the
traditional brake "calipers" are so close to the tire that it will be
REALLY difficult to put ANYTHING over the tires without it hitting some
part of the brakes. I could imagine a sort of knobby rubber belt that
wraps snugly around the tire, but I could also imagine it slipping off
sideways in turns or when maneuvering and locking up the wheel.
