Dynabeads - beads to balance your tire

[strsout]

Any one here ever used this product:

beads to balance your tire instead of weights.
Is it work?
Do you have in your car?
and in your bike?
Any comments?
Thank you

Interesting product.
I use Ride-On TPS (http://www.ride-on.com/) to ballance and seal leaks.
It works great!

I'm sorry I can't understand this.
I can't see how anything that can move inside the tire can balance it.
If anything it will seek a point farther away from center, making it more out of round. Balance those tires.

Hey Michael - we have a lot in common. I graduated from Kenston High School in Bainbridge in 1972. Got my first real street motorcycle, a new 1971 Kawasaki 250 Samurai in 1972. I've been an FAA Certified Commercial Pilot since 1982. I use Swagelok BRAND fittings on my hot air balloons and hydraulic lift gates on my trucks. Two of my best friends (one an old girlfriend) that I went to college with lived in Hudson. I still keep in touch with them. Small world, eh?

But I digress:

"The physics of how/why the free mass inside the tire automatically knows where to go is hard to conceptualize. The best way to understand why this works is to exaggerate the problem.

Imagine there is a 5 lb weight fixed to one place on the tire. When you spin that tire to normal highway speeds, it will be so terribly out of balance that the tire would probably hop off the ground with every rotation. The axis of rotation is actually moved away from the center of the wheel toward this extra mass because it’s pulling the whole tire with it as it spins. The free moving balancing weights inside the tire are not affected the same way by these forces. First as you get up to speed, centripetal force will make the balancing weight stick to the inside of the tire. Then the force of the unbalanced weight on the tire will move this balancing weight away from the imbalance. When enough of the mass is opposite of the imbalance, the vibration disappears and the axis that the tire is rotating on returns back to the center.

To give you another example to explain why the balancing weight moves away from the imbalance and balances the system, think about what happens when you accelerate fast in a car. Anything that’s loose moves to the back of the vehicle. This same force is created on an unbalanced spinning tire. The imbalance is jerking the tire sending the free mass inside away from it and the centripetal force holds it here."

Holy Cow Ron , there I was laboring over how to put hydrodynamic balancing equations into an understandable form and you went and made made it all sound so simple :D. Those are great examples.

This principle is used to balance all types of rotating machinery from jet turbines to grinders.

Stolen directly from their website - notice the quotes. "..." ;)

I buy it!

...but then again I am still trying to figure out worm holes. Stephen Hawking really pisses me off. :abduct:

I used to put antifreeze in the tires on my old 18 wheelers.........does the same thing and its cheap. :D

Use the stuff in my big truck tires. Works great except when you first start out. Not so sure about it in a MC tire. Every time you start and stop you might get some out of balance for a few feet.
