I put beads in the BMW rear wheels mainly because I don't have the adapter and they seem to work well.
When I weight balance I rotate the heavy spot to the top, move it both directions till it starts to move on its own then start placing two weights spread on the opposite till it balances.
But back to beads.
I think I understand how they balance in a vertical plane but how do they balance laterally, assuming they do?
How well do they work in a big tire where lateral balance is important ?
