Gentlemen, We in the trucking industry have been using two wheel balancing products for some time! The first is called Centramatic wheel balancer. This is a metal disk placed between the hub and wheel. It has a tube around the perimeter of the disk filled with ceramic beads. and the other is "Equal" a heavy powdered material that is placed inside the front tires. Both products rely on centrifugal force to distribute the balance weight, effectively re balancing the wheel every time the vehicle comes up to speed!
