When the tire spins, centrifugal force spreads the beads to the inner surface of the tire.
If there is a heavy spot, a vibration will occur. This vibraiton will cause a little more centrifugal force in the opposite
direction of the vibration so more beads move to opposite side of the tire. After several turns the beads will have all positioned such that there is even and constant centrifugal forces.
Anyone here ever used them???
