Here are the questions I have on the beads:
Since they don't stay in place, does that mean the tire becomes unbalanced every time you come to a complete stop, or slow down bellow a certain speed? How well will they work for those of us with heavy traffic commutes?
Also, if you look at the vehicles they discuss on the website, they seem to be mostly tall profile tires. Are these less effective on lower profile rubber? I don't see why they would be, but the thought I would ask anyway.
In either case, I have not problem balancing my wheels the old fashioned way.
