Tire Balancing Beads

Postby NtheWind » Sat Apr 02, 2011 7:17 pm



I have been reading about Dynabeads and similar medium used for balancing tires. Just a thought- I wonder if match-grade BB's would work? I have not tried them, or any of the beads yet, but it seems like an ounce or two of BB's would have the same effect as any other bead. Anyone have any thoughts on this?

Thanks.

Hello, I believe the dynabeads are ceramic and I know they are alot smaller than bbs, I have them in my front tire and have over 7000 miles on the tire with no cupping our uneven wear. I will definitely use them again when ever I replace tires . See ya on the road

I would be concerned that the BB's would have too much mass. The cermatec balls are made of ceramic and are very small, so can distribute very evenly inside the tyre. A ball bearing is quite large and heavy and so you would have all that mass in one place, I doubt they would balance very well.. I have the cermatec balls, and they are a bit expensive for what it is, but they do work very well so I will be using them in my next tyres..

I agree - I have Dyna Beads in both my front and rear tires. They are made of ceramic, and are quite a bit smaller than bb's:

You can hear them slide around almost like sand when you turn the wheel. You can see more here:

Thanks. It seems like the ceramic beads are the way to go.

must be some of these tires arent that far out of balance , when i had my new tires mounted , the mechanic did'nt put any on my front tire , it was almost perfect , i was'nt there when he mounted the back tire , what ever he did , they run smooth and i have no cupping so far , i took elite 2 off and just put reg dunnies on

I believe most tyres are very well balanced, it's usually the wheel that goes off balance due to the addition of different tyre valves, rim dinks, etc.. The great thing with these beads is that they constantly rebalance the wheel, so if your tyre wears un-evenly or you dink the rim on a curb, it will always be silky smooth.. Also a lot of shops cannot or do NOT know how to balance a tyre correctly so these are a god send. I am really pleased with the results I have seen so far and now have the beads in every motorcycle that I own (and there are a few!!).

This will be my first season riding with tire beads. But after I bought two bags of them I thought boy they look just like milling beads we use at work to mill our products.Sure as **** they were.. I brang them in and had two engineers and a scintest check them out and run a couple test.Same thing.I now get them by the gallon.Maybe google cermic milling media may help you find them cheaper.

thanks Sally, even with all my bikes, a Gallon of the stuff would see me through until I die!! Will definitely look at finding some of the beads (in smaller quantities than a gallon) as I do like to use them in every vehicle I own that does not have sensors inside the tyre (usually pressure sensors).

Gary

PS I tried a Google search but most of the media it lists is not spherical in shape.. Can you give us a few more hints about the make or model that you found matched at your work? Also what is the size of the balls?

Yes Dyna Beads might work but Centramatic Balancers will not only smooth out the ride but add to the handling of the bike, add 20% or more tire life, even out tire wear and you can put them on any GL1800. Plus you don't have to deal with putting in beads every time you have to change tires.
If you can get input from someone that had been using Dyna beads and tried Centramatic balancers you will find they all say they will never go back to beads.

I don't see how Centramatic Balancers will add to the handling of the bike compared to dyna beads. Centramatic balancers are heavier than dyna beads (You have a metal case & plastic tube to hold the centramatic balancer weights which you don't have with the beads) so this is adding more weight to the center of the wheel, therefore increasing gyroscopic forces, meaning the motorbike will turn (Change direction) slower, that is not improving the handling in my book, but my biggest issue is the $200+ cost to fit these balancers to every vehicle.
I like the Centramatic balancers, I like that you don't throw them away with every new tyre, I like that the weights are dampened, but I have 8 motorbikes and could not afford to spend $2000 equiping all 8 with balancers, where as I can afford $80 for 8 sets of Dyna beads.. I also like that Centramatic balancers can be fitted to vehicles with tyre sensors!!

Just not sure how centramatic balancers improve handling over dyna beads..

The bead size is between 0.9-1.0mm I will list where we buy them later I have to ask buyer off for Easter.If you can't find them I maybe able to set something up. I have plenty. Sally

I'm sorry guys, but I just don't believe it. I viewed the mfg'er website and they do not sight thee engineering principle on how they function. Are their other mfg'ers out there that do?

Sooo I have a wheel that is not in balance...why do the beads migrate to the area opposite the out of balance (heavy) point? I would believe the beads to find the "out of round" point by centrifical force...but that would align all the beads in the wrong place compounding any vibration.

Have you heard about the water softener device that clamps on the outside of your water main pipe to "re-align" the calcium so it doesn't stick to your pipes...Sean Hannity advertises it all the time.

No offence intender here, guys, just help me with the scientific principle behind all this.

I kinda agree with fewman. But like I said this will be my first riding season with them so I'm still doing my own testing to see.It's like nitorgen filled tire ?? I have been running it for two years still not sure if there any benifit to it.. Any thoughts ? I just want to let people know there may be other beads out there that work the same way.. I started mounting my own tires at home this would just be great because I have no way to balance them I should find out fast . Sally

Fewman, I agreed with you. I didn't "get" the physics behind how they worked. But I figured I'd give them a try. And they DO work. I've never been able to balance tires anywhere near as well as these beads do. The bike rides glass-smooth with them.

Thrasherg, I agree with you about Centramatics. They're going to work the same way as the beads (both add to the tire life because of the way they both even out tire wear), but the Centramatics add more unsprung weight - and unsprung weight causes a DECREASE in handling, not an increase.

I suspect the main reason Centramatic owners will "never go back to beads" is because they can't bear to admit to their friends that they paid $250 (Centramatics) for the exact same thing they could have paid $15 for (Dyna Beads). :)

cool vidio , i see they work , but gon't see the how , you would think well spinning they would be equal all away around the tire , thus making the tire the same befor ya put them in , if your tire was out of balnce , it seems like it still would be , but i did see them balance the bottle ,

Evidently you have never ridden a bike with the centramatic balancers. If you had you will find they do make the bike handle better. As for the last comment, with the extra tire life you get it well worth the price of centramatic's. It has nothing to do with the price, it is the ease of installing, the handling and the ride. To me, it is one of the best investments I have made on my bike.

I'll bet you have installed many things on your bike, that don't improve the ride but cost just as much as the balancers. Does that mean you can't admit you paid that much for them, I don't think so. It is all about what the individual rider wants. I am just giving my thoughts on what I have done and how well I liked it. Maybe someone else might appreciated knowing what others think and have done to improve their ride.
So if you use beads and are happy with them, continue to use them. If you want to improve your ride, try riding a bike with the Centramatic's. Then you might see the difference.

Perceptions are subjective. No harm or flame intended. I have always been curious about how things work. I would like to see a demonstation using a wheel and not a bottle. That demonstration could easily be set-up...

I have not rode a bike with either beads or centramatics.

I have my tires balanced on a static balancer using weights. If a balance or tire(s) replacement doesn't fix the problem, there is still a problem.
