Just bought new tires and had Dyna Beads put in for balancing. I remember hearing that the beads come in a bag and it takes a while for the bag to disintegrate and release the beads. Is that correct ?...
You'll probably need to start and stop a few times. The first time you drive, the bag will get pinned to a portion of the tire and stay there. The first time I drove with them, I went about 7 miles and they didn't break. After I started and stopped a couple of times they broke open. I was very impressed with them.
