quote:I'm not sure how small the ceramic bead blast media is.
What I have is the same size as the Dynabeads. Small enough to fit through a valve stem.
And by work, I mean that they will reduced/remove perceived tire imbalance from the riders perspective.
I must admit, Blake, you've worn me down on this. I feel like I am trying to explain why I ride a Buell to someone who swears by the imports. Some people just don't get it and aren't willing to give it a chance.
For me, I mount my own tires and friends' tires, and it is easier for me to dump in some beads than it is to set up the Parnes balancer.
I bought several pounds of the media, I'm not selling it, so have no vested interest other than that I feel it works well. |

You may feel that way, but the truth is that it doesn't. |

I perceive that my vehicles run "oh so much better" after an oil change or a wash job. |

Glitch you are Sooooo right! Send it in and ask if they'll use the 1125r they have in the shop. I think Jaime owns it. |

They will need transparent tires, but then the dynabeads will know its not a real tire and then not work! |

they could run the tires on a dyno machine and measure vibrations |

Perhaps its more than just perception? They most certainly do not balance the tire, but having loose masses inside the tire would seem to constitute a crude torsional damper. Rather than removing the imbalance it would spread out the impulse of the vibrations over time at some specific rpm so it isn't felt. Of course it doesn't appear that any work has been done to figure out just how much to use in what size tire to dampen out however much imbalance at whatever speed (the beads apparently know what they need to do and act accordingly on their own?) A band-aid covering up the problem rather than just fixing it. |

Except for the fact that it won't work on a spin balancer. |

because a spin balance is a test
Dyna beads don't play your silly games...
no wait that's black cats...
maybe it takes your suspension flailing about wildly for them to work, and once your shock mounts have worn out you cant feel it anymore. |

right, because they wouldn't balance the tire, just attenuate the vibrations where a human being would feel it, but the machine would still detect it. |
