A friend who goes by "Partspig" on many forums has a die that he uses to stamp out blanks from flip flops. They fit HO hubs well, and can be ground down to nearly any size from dragster and monster trucks down to racing slicks. Just need to trim down the width while spinning them on a mandrel using a straight edge razor blade. I have a bag full of them, but haven't had a chance to finish them off yet. I think he recommends coating them with flowable silicone after sized and shaped. A bit of work I suppose, but available in lots of fun colors, as well as basic black.
