cheeze1 - I also have no "hands on" experience of the miracle beads. There have been some postings on the subject like this one
Wheel Balancing. I'm like you if Burl says it works, I would believe it. ;)
Most tires of recent vintage have yellow or red dots near the bead that are used to line up with the valve stem hole in the rim. Theoretically, that yellow spot is the lightest on the tire and should be where the rim is the heaviest (valve stem).
I believe that if a red dot also exists, it is the spot where the tire is most out of round (maximum runout). You would match that to the dimple on the rim. If you cannot find a dimple, match the red dot to the valve stem hole. Then use weights to counterbalance. The red dot trumps the yellow dot.
