Late to the party here, I had a local guy who’s only business is motorcycle tires (for fat slow cruisers) put my supplied tire on rim on a ZRX1109 and I had terrible speed wobbles on hard acceleration after. I inquired if it was balanced looked at install etc. found out eventually it had these beads in it. Had them removed and balanced at another shop because buddy refused to deal with me and problem solved. I believe in a static speed they may shake out to the balance point, but while torque is applied the beads will be all over the bloody place causing my speed wobble.
I now have a No-Mar and static balancer and take care of my own tires.
