I'll start using it, when tire manufacturers start recommending it, instead of voiding warranties... not that tire warranties matter that much, but if you had an issue, legally, they would use that against you.
I must agree. Car manufacturers do everything they can to save pennies on every car they make. Lead weights are expensive because lead is classified as a hazardous material , and a variety expensive safety precautions are required in its manufacture. Used lead wheel weights are expensive to dispose of as they are classified as a hazardous waste, in many states, requiring strictly controlled disposal methods, at serious cost to the tire shops.
If Dyna beads worked all the time, then the car manufacturers would have long since bought the patent, or at least licensed their use. Also, anything that worked that well would have made the news media by now, as the beads would eliminate a serious environmental problem (manufacture and disposal of toxic hazardous material and then waste, lead weights). If they always worked reliably, consumers would have known about this for some time now, via the media.
Search the net, and you will find consumers stating pro and con opinions, based on their practical experience with the beads. This product does not work well for everyone, which is probably why Detroit won't use it, why tire manufacturers void your warranty (buy a set of new tires and refuse to let the store balance them because you intend to use the beads, and watch what they say to you), and why it hasn't caught on big time with the motoring public.
