Seriously, I can't see how these could possibly work, either. The fact that the tire is somewhat flexible would seem to argue against them - the beads would pool in a spot that's slightly farther from the axle, causing it to flex out more, causing more beads to pool, etc.

Also, the contact patch of a tire is a slightly flattened spot. As that part of the tire comes into contact with the ground, it would cause the beads to be flung away from the rubber towards the wheel rim. This energy for flinging the beads would have to come by way of increased rolling resistance, and that's not what you want in a high-speed tire.
