When this was posted last time I also mentioned
www.innovativebalancing.com - once the Dynabeads are installed, including using tubes, you never have to balance your tires again.
Someone asked about what happens when you get a flat - I did have one one e tubeless rim off the rear of my 40 coupe. I told the tire place of the beads but he was skeptical of the outcome and asked me to watch. Repaired the tire no problem using an inside patch and the beads just rolled off to the side.
