The explanation on page 5 leads me to believe too much is not a good thing, especially if its a lot too much since the beads, not needed for balancing, just spread out on opposite sides uniformly.


You're probably right, too much of a good thing is just adding unnecessary weight to your tires; but what I was trying to point out is that they were talking about 'centrifugal force', which does not exist. They are stating that the balls are pushed to the outside, while in fact the tire is pulling them to the inside.
My question is still if anybody has checked the inside of their tires since they've done this? Any inside tire-wear or broken/worn down beads?


I only have about 1000 miles with the beads in, with no problems. I haven't found any evidence on the web of bad things happening. I've found a few more manufacturer of these dynamic balancing media

looks like for smaller tires they are using a powder that can be installed into the stem, this also requires installing filtering stems to keep the stems from plugging up. For larger tires the media is beads and you have to break the bead to install, but beads are too large to plug stems. The airsoft beads look like a pretty good match, although a little lighter than the ceramic media blasting material that all these places offer.

I like the idea of going with the dynabeads because they are a proven design and I don't quite trust the airsoft beads yet. How do they react to thermal and moisture changes, and how well do they hold up over time?

I also like the capability of adding them through the valve stem...much easier and more convenient for me.

update on my experience so far.

After about 6000 miles, wheels still balanced, no problems in most situations. I do notice that when I go around a high speed curve, the tires come out of balance. Usually just momentarily, but I've had at least one instance where I had to slow down to get the tires to balance. This curve (35mph to 50mph transition and a fairly tight turn) is on my way to work so I've had lots of time to notice the effect. symptom is the steering wheel shakes a little. Not a lot, enough to notice.

The tires I've had on the front have about 6 oz of beads in them. I've rotated those tires to the back. I now have 2 oz in each of the front tires. I suspect that with less beads, I'll notice this effect less, but will keep you updated.

This isnt a new practice, I know guys who have been running BB's for a couple years. The bb's tend to rust tho so the air soft pellets are best. Even better are beads actualy designed for putting in tires.

You will never get a true balance with them but on a 35" or bigger mud tire you'll get more vibes from the lugs hitting pavment than the incosistancey of the balance
