Liquid tire balancer

[harold]

I recently replaced my tires on my Baghira myself, and they shook worse than the old tires. Searching the web I found balancing beads made by 2 different companies, and then this balancing liquid called Ride-On. I bought it since I have tubes, and it also is a sealer. Well, it works. I took the bike for a 3 mile ride to distribute it, and by the time I got back the bike was running very smooth. If I had tubless tires I would get the beads, since you can reuse them when you change tires.
Much easier than pulling the wheels again, and taking them somewhere to try to balance.

the liquid is not a good idea in a tubless tire as it may eat at the rim
and damage it

David,
Actually the liquid ends up on the middle of the tire from centrifical force. The have a little video of someone washing it out of a car tire with a garden hose, and the goop is only on the inside of the tread of the tire. That is why they don't claim it will seal any punctures on the sidewalls. I was afraid of putting beads in a tube, but the way all of these are supposed to work is they move until the tire is balanced, and then stay there. Prolonged sitting of a couple of weeks is supposed to drop them back to the bottom.

This was the best affect on my bike for $30 that I have had yet.

Wow, as opposed to some lead weights for £1? Or balanced professionaly for £5?

A liquid can only coat the surface, and under rotation it will coat it evenly, it can't improve balance from a tyre or tyre and wheel assembly that has a heavy spot.

You should see the YouTube video of a coke bottle spun with a drill and a 1/2 ounce I think weight taped to the side. They do it with and without the beads. While the beads and the Ride-On distribute around the circumference, they both balance by putting more on the light side. I saw the video, bought a competing product, and felt the results. Unlike most products, your results will not vary. Its physics. I only bought the slime because I have tubes. The beads are totally reuseable in a tubeless tire.

Then I guess I need someone to explain the physics to me, (wont be the first time!) and probably so do all the folks who waste time money and effort on finding exactly where the heavy spots are, and countering them with a specific amount of additional weight, when all you have to do is throw some beads in there.

Physics would suggest to me that you would need to add a rotational mass that is far greater than than the original imbalance in order to counter the feel of the imbalance. So more rotational weight than if you balance the wheels in the traditional manner, at more cost?

Am I missing something here?

By the way, googling "coke bottle balance you tube" brought up some interesting results, but nothing that I was actualy looking for.
