I said in my previous post that I would do an update on how the air soft BB's worked for balancing my tires on the bug so here it is. They work awesome! I have felt no vibrations whatsoever. I am now 100 percent convinced that they work and they work well. I am going to run them in all the tires on my bugs. If you missed my first post on the subject I will give you a rundown on what I did. I bought a bottle of air soft BB's and separated them into bags of 3.5 ounces each as you can see here. I got 10 bags out of 1 bottle so I have 2 1/2 cars worth of beads.
