The last time I put a new tire on just before my summer trip I was blown away by all the ugly weights used to balance the tire. I'm running an Avon 120/80 on the rear. Sooo....I'm going to try using the ceramic balancing beads this time and was wondering if anyone else has used them. Looking for testimonials, good, bad or ugly. Thank ya'll | ||

I personally have no experience with them but there are a couple fellas on this board that are firm believers in the Dyna Beads. I'll just bump this up and see if it gets their attention  | ||
| Barker |
yes, they work. very well. this is good demo of the physics. | ||

This was a long debate the last time it came up. Some people said they would test them on a dynamic balancer, no results posted yet. I believed at first, I even bought them. Now I think its just a scam, I tried my own bottle test and didn't get the same results. If the beads work, why not just use antifreeze/water. I'm waiting for a more conclusive test before I put them in my tires. | ||

Notice how he doesn't spin the bottle without beads at the same speeds as with beads? | ||

Oooooohhhhh boy.... Don't let Blake get wind of this! | ||

Ooooooohhhh boy - I should know better by now to do a search before I just do a post. I was in a hurry, as usual and posted before I took the time to do the research through this site. As always - there will be pros and cons, supporters and non-supporters - and that's what I like about this forum - you get honest feedback. OK, bring it on Blake  | ||

Here's my thinking. The beads are being pushed to the outside of the bottle by centripital force. The further away from the axis of rotation the beads get, the higher this centripital force is. Naturally, they will migrate to furthest point away from the axis. If the weight is causing the bottle to spin lopsided, there is one spot (where the weight is) that is furthest away from the axis and the beads will be drawn to that spot, increasing the unbalanced wieght, not fixing it. But what the hell do I know. | ||

But what the hell do I know. Here's my thinking. An out of balance wheel will not want to spin around it's axle. It will want to spin around a point slightly closer to the heavy side of the wheel. This means that the light side of the wheel is farthest from where the wheel naturally wants to spin causing the beads to gravitate to the light side, fixing the unbalance. But what the hell do I know. I've never tried them myself. Not sure I ever would. I do enjoy stirring the pot though!  | ||

All the ugly weights? You shouldn't need that much if you're using a quality tire and its mounted correctly. You could be really anal, mount and balance the tire, remove the tire and place the weight inside the tire. | ||
| Blake |
Pure, unmitigated snake oil. | ||

The wheel is pretty much in a "fixed" axis,the bottle is not on a fixed axis. If the stuff worked,wouldn't the factory use them ........instead of going thru the trouble of balancing the wheels on every stink'n vehicle they produce? | ||

Here we go again! Well i have not done a dynamic or road force balance as the machines don't go fast enough to prove anything! Now i have tried these and the do work. in the correct amount for the right size tire. That you-tube video is not accurate at all. So here is the problem we were having...The tires were pirelli brand top of the line on a dodge SRT-10 Viper truck. my brother owns it and works in tire sales with me everyday so i have felt the results. Now we balanced these tires over and over and over on 3 different machines and 2 different types of balance methods including different types of weights i.e. lead clip on, Adhesive tape weight, and a hybrid flexible adhesive tape weight to go on wheel and up the wheel. Still shaking! WTF? So we had the driver go and get some of these in town, Then We installed these into each tire with no weights at all and put right back on the truck and guess what....Smooth as glass. Now i have been doing tires for years. That's what i do for a living and i have never believed these would work! like BLAKE says SNAKEOIL! But now i have seen that they do work and felt the results so i can say no more on this. Oh wait we were also using these on the big torque pickup trucks that actually spin the tires on the rims enough to shift the balance of the tires when they were loaded up!

had new steer tries put on my isuzu city truck no balancing at all just the dyna beads. smooth riding. | ||

Yes any wheel shop or tire store can get them for you. | ||

If magic beans, I mean dyna beads worked. The major car makers, and motorcycle makers would be using them. N.V.H. is a major concern with modern vehicles. A simple one step solution would be widely embraced if it totally eliminated one of the three, in this case vibration caused by tire imbalance. http://en.wikipedia.org/wiki/Noise,_vibration,_and _harshness | ||
| Just_ziptab |
N.V.H. ....ah,I remember that acronym well when working at the Ford garage. Was a challenge to find odd stuff on brandy new cars like a goofy ring a pinion or tight u-joint causing it all........../ | ||

I use the beads and like them. I've also used them on a friends tires without telling him, and he never noticed. I did tell him after the fact, but not initially. As to the believers and non-believers, I say pay attention to the ones who have used the product. | ||
| Sifo |
I do find it intriguing that there doesn't seem to be anyone who has tried them and didn't like them. Have I missed that post? | ||
| Iamike |
We noticed Michelins don't even use the yellow dot on their tires. I haven't had to balance any of them that I have put on recently. Of course most of the Dunlops and Bridgestones were pretty good too. I use the Marc Parnes balancer. | ||

I know a badwebber that is local to me and he does his own tires. He doesn't balance them! He swears that modern sport bike tires are already pretty good and that he can't tell the difference. Dumbo's magic feather? They just don't INTERFERE with an already balanced tire? I wish someone would deliberately unbalance a tire with lead weights and see if the beads would counteract it. I don't want to pay to see if it works! | ||
| Thetable |
It's been done, non-believers still don't believe. Of the last 10 or so tires I mounted up before going to the beads, I think I had one that balanced without any weights, and two that balanced with a quarter ounce. Tires have gotten better, but they aren't that good yet. | ||
| Blake |
"It's been done, non-believers still don't believe." Baloney. This topic has been discussed ad-nauseum. The beads can act as vibration dampers. They do not balance anything. The bead video using the coke bottle is a brilliant con. But it is a con. | ||
| Blake |
"yes, they work. very well. this is good demo of the physics. " No they don't. That video is a brilliant con. Conditions were manipulated and controlled just right. And do you see the bottle being perfectly balanced? It still vibrates to the extent that if you scaled it up to the size of a tire, it would be ridiculous. An out of balance tire doesn't deflect inches, only tenths or hundredths of an inch. That bottle is about 1/10th the dia of a tire. It is vibrating on the order of hundredths of an inch. Scale that up to full sized tires, you have tenths of an inch. Pure, unmitigated snake oil. What do you imagine happens when the beads encounter the flat spot inside the tire at the region of the tire to road contact patch? | ||
| Blake |
"Even at low rpm the bottle wobbles quite a bit" LOL! Then he pours in a whole ounce of beads into the tiny, relative to a tire, little bottle. Then he claims that "once it gets to speed, it runs nice and smooth." Baloney. The bottle is vibrating like crazy. It's not wobbling like a drunk sailor as in their initially contrived non-bead scheme, but it sure is vibrating! Why are people so eager to believe this kind of crap? Then the placebo effect takes over. Well if you don't drive too fast and your tires aren't too far out of balance, no beads will work well too. You won't ever notice a problem. But your tires may eventually wear unevenly and prematurely. There is no free lunch. There is not magic bead that can overturn the laws of physics and magically balance a tire. | ||

Blake, you are vehement on this. Have you ever tried them, or know someone who has? Maybe they are a hoax. Maybe they work. Open-minded curiosity fuels the best inventions and discoveries. I'm neither sold on them nor rejecting the idea outright, but I would be willing to try them, just to see and report. | ||
| Sifo |
I would love it someone like Blake would take a wheel that is out of balance (add weight to unbalance if you like) and try the magic beads. Like Fahren I'm neither a believer or a disbeliever on this. Someone like Blake would make a great test subject though. I doubt he would give in to the placebo effect in any positive way. Now, how to get Blake to test the magic beads? | ||
| Glitch |
Well, since proving a negative is less than positive. I suggest someone to prove them to work. take a wheel that is out of balance (add weight to unbalance if you like) and try the magic beads. | ||
| Pammy |
What happens when you lean the wheel/tire aggressively at a high rate of speed? How would that be on a curvy road where you would be accelerating...decelerating and leaning...accelerating...etc...? Seems to me that the action of those beads would resemble something moving inside a blender. I'm just sayin' |
