I've seen it done once. A tire place did it on the 35's my uncle got put on his Dodge Ram 1500. I thought it was pretty damn cool. I had never seen such a thing before. But, like Roger says, it's not for passenger vehicles. Although, it would be cool if they could make it work for passenger vehicles, that way we wouldn't have to use wheel weights on a nice set of rims.In my experience with beads i was told they were only to be used with massive truck tires. And yes when we put them in large truck tires they worked great.
