I have a Volvo 240 that I bought cheap Fuzion HRi tires for with some old turbo wheels. They shook like hell even after they were balanced at the tire shop. At 75mph, the whole car bucked and shook. I put 3oz of dynabeads in each tire and it smoothed things out, but not all the way. I got the wheels rebalanced at my tire shop and now they're smooth to 100+mph. The tire balancer machine got the same result each time when spinning up the tires with the beads in them, thankfully.
@frescoces - If you don't want to use them, then don't. Nobody is forcing you to put them into your tires.
But the fact is that they work. - PERIOD!!!
And unlike powders or liquids, Dynabeads leave no trace inside your tire, so there is no way to tell they had been used if you do have a warranty issue. No problem!
btw - When WAS the last time you had a warranty claim on a tire?
What about uneven wear from an out of balance tire?
I have been using Dyanabeads in my motorcycle for several years now and love them. Recently I put on a new front tire and the shop did not have dyanabeads so I just have them balance the tire normally. At about 70 mph the tire had a shimmy, this become such a pain that I order Dyanbeads on line, took off the weights the shop put on and put in the beads. The bike handles great now, I guess I never knew just how well they worked until I didn't have them, I even use them in my car now.
Has anyone tried BB's? BB's weigh a fraction of a 1/4 ounce (the small size of metal weight for balancing tires) and fit inside my tire's valve stem.....
@LiveHappy76 - Some trucking fleets even use golf balls inside of the large tires on their semis...
But a steel BB is not as dense as the ceramic used in Dynabeads and is larger diameter, meaning it won't concentrate the mass as well at the point of imbalance.
Also any moisture inside of the tire (condensation) will cause the BB's to rust and start to clump together and become rough and abrasive to the inner liner of the tire.
Started using these on my 2007 Triumph Rocket III Classic Tourer two years ago, after the original rear tire wore out. The difference isn't immediately clear; new tires, freshly mounted and balanced feel the same, but after a few thousand miles and some uneven wear (due to imperfections in the tire itself - thus the need for balancing) the Dynabead'd tire still rolls smooth as silk! Replacing the front tire today - you know it's getting the beads, too.
It would be good to see a demo of a tire mounted to a balancer. See what the reading is and what weights are needed. Add the beads and then check it again. Do you have anything like that?
@tykesplace - Read through the comments and replies, this subject has already been covered.
Dynabeads need an axle that is free to move in order to redistribute properly. (like a wheel on a car/bike)
A fixed axle balancing machine won't let an unbalanced wheel move freely as it would on a vehicle moving down the road; therefore, the Dynabeads won't work as intended.
how come there are not any video's showing real proof these work? they are for a tire right...lets see them demonstrated with a tire, not a plastic bottle.
Also i hear not to check your tire without a air compressor near by, when the bead gets stuck in the valve-core, your out of air.
@theyamaha700 Well, if you have a clear tire that we can use, to prove that the beads are inside and working during the demo, bring it on over! ;-)
The physics are the same as a wheel on a suspension.
As for the valve core; I have been using DynaBeads in ALL of my tires for over 5 years. I check the pressure in my tires each morning and have never had an issue with a valve getting stuck open.
You simply ensure the valve is aimed to allow any beads roll out before you open it.
can these been used in drag tubed slick?? if so, will it weigh more than just regular weights do to the size of the tire?? i've never seen this so i'm a newbie to it
@ezcondition Racing applications, particularly drag racing would be one situation where these would not be recommended. Due to the severe changes in wheel speed (spinning) the beads would have a hard time matching the change in speed due to different momentums and the lack of friction inside of the tire/tube.
I used dynabeads in a 2003 Honda Rebel 250 for over a year; the bike ran smoother than it ever did than with the old lead wheel weights in the prior 3 years. I am sold on this product and will use them in my new bike.
They never spun the bottle at high RPM with JUST the weight. It would have reached the same "appearance" of being stabilized guaranteed. They try to dupe you with slight of hand, by running the beads longer and faster until the bottle "seems" stable. The weight alone would have attained the same "zen" given half a chance.
@cleefurd: It is "sleight" of hand, and no, you are wrong.
Running any faster with just the external weight and no dynabeads would risk ripping the bottle right off of the flexible shaft and possibly hitting someone.
THAT is why it was not run up any faster.
Feel free to try it yourself. Wear eye protection...
@blue03r6: If that is the case, it is new. The last time I directly contacted Bridgestone/Firestone/Dunlop (all the same company now) they reported that they only restricted the use of liquid/gel sealants and balance agents inside of their tires. But it is possible that the policy has changed.
How often have you had a tire warranty claim vs. cupping or feathering wear from poor balance?
@blue03r6 I can't see how these little beads would do anything to harm the inside of a motorcycle tire. I think they are just trying to cover their asses. The inside of my michelins feel impervious to ceramic beads, but what do i know.
Once the tire is up to speed and the beads have distributed, they no longer move.
Over the road truckers use the same product in their tires for hundreds of thousands of miles per use and multiple retreads without wearing out the inner-liner of the tires.
If true quite impressive. You seem to have an awful lot of information on this product as well as knowing every conceivable selling point. Do you work for the company? Worth the money over weights or wouldn't small gauge shot (steel or lead) be better?
However, steel balls will quickly rust if there is ANY moisture inside of your tire.
This will lead to them clumping together, not rolling well to distribute properly, and shedding dust which could foul your valve core.
Also, larger objects like BBs have lower packing density, reducing ability to concentrate mass at the point of imbalance for effective balancing, and cannot be added through the valve.
I think the problem with a balancer demonstration is that the balancer speed is too slow compared to road speed. As you can see in the demo, it takes a certain rpm to get the beads distributed.
The problem with trying to test Dynabeads on a 'modern' electronic spin balancer machine is that the wheel is on a rigidly mounted axis with strain gauges attached to it to measure bending stresses.
It is not allowed to move freely to let the beads redestribute naturally as they would in a which was wheel free to vibrate naturally when mounted on a vehicle.
The beads need the initial small wobble of the wheel to find the correct balance point. Then they stay at that point and do not move.
I've used DynaBeads on my last 4 sets of tires (BMW R1100R)
My son uses them in the tubes on his KLR 650. My brother has used them on his last 2 sets of tires ( BMW R1200C) and a friend of mine uses them on his K1200LT and Kawi Z7,they work GREAT!! no problems at all . Tires NEVER need re- balancing. They are constantly re- balancing themselves. We've used these things extensively on a lot of different bikes with alot of different tire sizes and brands and tires ALWAYS wear evenly and feel good.
If the product is good for balancing tyres, why are you not showing an imbalanced tyre on a balancing machine and how you correct the imbalance with the beads?
Or why not put a camera on an imbalanced tyre on a motorcycle going down the road. Then add beads and film again?
This would be much more convincing evidence than playing with water bottles.
there is no way of visually telling if the tire is off balance... this was a perfect of representation of how dynabeads work and how effective they are in balancing circular object rotation..
I disagree. They could mount the tire on a commercial tire balancer like my tire shop has. It has a digital read-out of the imbalance. It would be perfect for a demonstration.
How do you know how much dynabead to install? Is it always 1 ounce? It seems to be more work than a static wheel balancer and there is always this feeling of uncertainty. Confidence in your machine speaks volumes when you are riding.
this will only work under perfect smooth conditions and does not actually balance the tire!! imagine if your moving and the road is bumpy, the beads will not stay in place and the tire will stay un-balanced until you hit smooth road or even the centrifugal force again. they would work better if they were to stick in the same place they initially settle in. constantly bouncing around in your tire wont work as well cause you would feel the tires wobble until you reached a certain speed.
Not sure that I understand all of your comments. The demo SHOWS that the product corrects an imbalance...
And I have worn out several sets of tires with DynaBeads installed which wore perfectly smoothly (no cupping, no feathering) indicating that they remained perfectly balanced thoughout their life.
If they had been bouncing around on bumpy roads as you suggest, they would have cupped badly.
Guess I will have to post photos of the used tires on the website. Thanks for the idea!
I'm thinking you might not have been paying attention in physics class when the law of centrifugal force was explained... with very little speed (10-20mph), the beads will be forced to the inside wall of the tire so hard that they can't possibly bounce around. And sticking them in place would be of no benefit as the tire wears, which does not occur perfectly evenly. The beads need to be able to reposition themselves as the mass of the tire changes unevenly.
The ceramic material used in DynaBeads is denser than water, so it concentrates at the point of imbalance better, and less volume of material is required inside the tire.
Also, water inside the wheel can cause corrosion of the wheel & valvestem. Even an aluminum rim can corrode when left constantly wet. And if water froze inside of the tire or valve core???
And finally, a tire plug will fail if water got in the puncture too...
That is just simply awesome! Never before has such a simple little thing amazed me so much. Why did it take mankind this long to come out with these things, when the wheel has been around for ages? Goodbye lead weights - they're so 19th century!
very nice demonstration. That pretty much covers what i wondered about with them and how quickly they balance a tire from a standstill.. Thanks for the demo
The video is not comparing apples to apples. You need to spin the bottle with the 20 grams of lead weight, and then remove the lead weight before inserting the Dyna Beads, and lets see what the bottle does.
The weight taped to the bottle is what causes the initial imbalance for the demonstration. Without it, the bottle just spins normally. There would be nothing to see, as the DynaBeads would just evenly distribute inside of the bottle as it spun.
If you are down by the wheel listening closely while you are rotating the tire slowly you can hear the beads tumbling. But out on the street with the bike running you will never hear a thing.
Plus, once up to speed the beads stay in place inside the tire, so no noise.
The only time that I have heard of damage to a tire is when using them in a race slick on the track. Evidently the inner liner on race tires is different. Possibly for weight reduction. Every ounce counts in racing.
That's crazy awesome! I saw an article for these beads before and thought that the concept seemed pretty counter-intuitive; I still do, but I'm sold on them. I may have to stop by and get some for my KLR next time I'm in the area.
Yes, it can take 2-3 seconds for the beads to distribute as the tire is coming up to speed. You can see that in the video.
However, a wheel is not spinning fast enough for an imbalance to cause problems in those first moments...Unless you are in the habit of doing burnouts...
So, DynaBeads might not be for those who leave clouds of smoke when they hit the gas.
But then I would say their tires have other problems besides whether they are balanced for the first few seconds of take-off...
The motorcycle tire makers I checked with only list liquid sealants as voiding warranties.
Trucking fleets have used them for millions of miles and pay hundreds for each of their tires. If there were a warranty issue, they wouldn't use them - Period.
You clearly seem to have a personal axe to grind, since you felt a need to come up with another slam when I disproved your first attempt at discrediting how well DynaBeads work.
Do you own stock in a company that makes wheel weights???
I have a Volvo 240 that I bought cheap Fuzion HRi tires for with some old turbo wheels. They shook like hell even after they were balanced at the tire shop. At 75mph, the whole car bucked and shook.

Let me make something clear - I am not selling Dynabeads.
I am not telling anyone that they have to go out and put them in their tires.
The video simply demonstrates that they do, indeed, work as advertized.
Yes, I have Dynabeads inside of every tire on the three motorcycles that I personally own and ride.
Since switching to Dynabeads I no longer suffer from any feathering or cupping wear on my front tires, which was common with weights.
I like them, you decide for yourself...

A pea on the end of a steel I-beam induces bending stress, but the deflection cannot be measured for practical purposes...
Rigid spin balancers are designed to withstand HUGE out of balance forces for safety.
Any deflection occuring is measured in thousanths of an inch, not the kind of freedom of motion required.
