I didn't have good results. Sure, I noticed the smoother ride but my tire wear did not come out even. I put the beads in a new tire and took off the weights just as they said, but after about 12,000 miles or so, you could see and measure a big difference in tread wear from best to worst 180 degrees on the tire.
When I complained to Dyna Beads, the guy tells me that this can't be because NO ONE has ever complained before. He went on and on and would not listen. I said why don't you just tell people to leave the weights on and enjoy the smoother ride but he insisted to take the weights off. So, screw you, Dyna Beads. I'm sure he is saying he never got one complaint.
Now I use Ride-On in my tires. They tell you to leave the weights on and I get very good, even tire wear and life since using that product. Plus, I enjoy a smoother ride and it preventing flats. Just get Ride-On and do yourself a favor staying away from Dyna Beads. I've used them in about 6 tires throughout their life and never had an uneven wear problem.
