They just magically go to the place that needs weight?

 

So its just a magical kind of thing LOL

 

It is centripetal force. Mass moves to the lightest area when spinning at speed. It's a physical law. There is a you tube video of a water bottle on a drill that shows the concept.

 

Unless its something else these didnt work for me

 

Correct we have people put them in their motorcycle tires they seem to work but you should check out this stuff called ride on tire sealant it also balances and stays in place it's pretty cool we use for custom wheels so you have no weights on them. The stuffs not cheap but it works and the videos are cool

 

What size tires are you running? I have 35's and only used 8oz. I know people say you cant use too much weight with them, but is it possible?

 

37s and 12oz

 

Noise factors? Rolling maracas?

 

When the tire is not balanced, it causes an elliptical movement -- that's what makes the vibration.
Centrifugal force pushes the pellets to the far end of the ellipse, which balances the tire.
When the tire is balanced, the rotation is circular, and the pellets spread evenly.



I guess that there is rapid oscillation between balanced and not balanced.

It can't work at low speed when there isn't enough centrifugal force.

 

The only time I hear it is when I come to stop quickly and actually have the window down listening for it. FYI this is also my daily driver so I am on them every day.
