I am also curious as to why one would need to remove ALL static weights... If the Balance Masters can eliminate vibrations from out of balance wheels, why can't they eliminate vibrations from wheels that are only slightly out of balance???
It could be they "need" to see some out of balance to work effectively. For example if a tire/wheel was in balance then the media inside the product would have a hard time figuring out where to locate itself since it relies on the upward swing of the assembly.
Sounds confusing but if you take a look at this product and how it works I bet the theory is the same.
