Anybody on here that mounts their own tire ever use dyna beads. If so what's your opinion on them and what happens when you change the tire next time. Plus interested in getting a tire balancer any good buys out there! | ||

I have them in two bikes and will never balance a bike tire again! Make sure the inside of the tire is dry so the beads will not stick together. Supposedly you can retrieve them and re-use them but I haven't needed to replace a tire since I started using them. | ||

Lots on this in the KV and elsewhere here. Blake and some others on here insist they are snake oil, however as they gain more use and acceptance in the biking world outside this one forum, we see more and more reports that they do, indeed work for riders. Also with caveats: they are not for race tires, since the inside of those types of tires do not work with the beads - this is stated on the bead web site. I have suggested to Blake in a past thread just to try them - so he can show everyone they are snake oil. But he has decided not to, so I have them, ready to go in within the next month or so. I will try them, I am open minded, and I am not silly enough to do it in a way to risk life or limb, so I will take it slowly and see for myself what's up with them. I have no stake in the company, I just like innovation. And sometimes new stuff works, sometimes it doesn't. If you have any problem with dymabeads, there's this other, cool, easy way to balance a wheel using stick-on weights on the rim :-) People been using it for a long time, no issues with it, no real reason to switch, since getting little beads into a tire isn't as fast and easy as sticking weights on. | ||

Hey Spidey! Where's that Facepalm?  | ||

Agreed. try them out and take it slowly. I slowly accelerated up to 120 and it was as smooth as a baby's bottom. I don't ride that fast any other time so I know I have a 1.3 or better safety margin. That was on a firebolt; the blast topped out just fine. | ||

Tell ya what. If you have the beads. Dump 'em out, and ride. You'll not tell the difference. | ||

Test them and report back. Put a one ounce wheel weight at a random spot on the rim and see if it compensates for it.........then move the weight 180 degrees and see if the results are the same. That should be the proof of it all. | ||
| Billyo |
If I remove the beads, then go for a ride-if the ride does not change then that would mean that the whole wheel assembly was balanced to begin with, correct? I won't go through the trouble of emptying them out but I like the idea of throwing a weight on the blast when I get a chance (firebolt is recovering right now). If they're a waste I want to know it too but I seriously doubt I bought two sets of tires that needed no balancing. I'll try to do it tomorrow. | ||

If they're a waste I want to know it too but I seriously doubt I bought two sets of tires that needed no balancing. I balanced my wheels years ago, I haven't bothered balancing the tires. | ||
| Billyo |
I'll get 1oz stick-ons. Will 1oz be enough to notice a difference? I've never ridden a bike that I knew had out of balance tires. | ||

I've never ridden a bike that I knew had out of balance tires. If you're riding on quality tires, the technology used today produces a well balanced tire. | ||
| Natexlh1000 |
How many ounces of beads did you put in there? Make sure you don't put more unbalanced weight than the beads are theoretically capable of compensating for. Motorcycle consumer news said that they are snake oil. They don't have any axe to grind in terms of sponsorship. I'm kinda thinking that it's one of those things that does no harm but doesn't actually help either. My friend mounts his own tires and never balances them because he said that modern sportbike tires are already pretty much perfect. I don't think that's true either  I have the dealer mount my tires and each time, they balance it with a few weights. | ||

Last set of tires I had mounted had like 7 weights on it when I got it back. I promptly removed the weights and cleaned the sticky gunk off the wheel. Also smooth as a babies bottom. Highly precise tire/wheel balancing is just not all that necessary. Leads me to believe that they do nothing....also the physics of their claims does not make much sense. | ||
| Reepicheep |
FWIW...
For the record, I *don't* have them in 4 bikes in my garage, and probably won't balance a tire again either. I left the weights on from the last spin balance. I run scorpion syncs (though the next tire will probably be a scorpion trail), and I understand those are completely computer assembled at this point, no hand layup anymore. So in terms of consistency, they are pretty remarkable, which is how they get away with such a thin and light carcass and produce such a light tire. | ||

I bought them and tried them and did not notice any improvement. My wheels weren't really out of balance to begin with though. I believe they're snake oil until there is proof otherwise. The last conversation here someone said they were going to test them on a dynamic tire balancer, haven't heard about it since. If they work so well, why isnt every major auto/moto manufacturer using them? | ||
| Ft_bstrd |
If you are going to use them, make sure to get the teflon beads. They are the best! | ||
| Natexlh1000 |
their own site said that they don't work in a spin balancer because they say the thing is bolted down and doesn't allow the tire to wobble. | ||
| Redefine420 |
I think that's a lame excuse to cover their ass. I don't have a degree in physics, so I guess I cant argue. | ||

Thats like saying my flashlight wont work indoors because the floor emits EM radiation that prevents the bulb from coming on.... | ||

when i took the wheels in with the new tires to be changed, the people who did it said that's all they been using but once i get above 90,i'm vibrating. i need to take off the windscreen just to make sure that it's the tires and not the screen. the only thing is, i haven' heard anyone complain about problems riding with the palmer brackets and a taller windscreen | ||

Where can I get said 'Snake Oil'? How many miles between oil changes? How much more horsepower/torque? Will Snake Oil weatherproof the conchos on my S1? (Message edited by roadcouch98 on June 07, 2010) | ||
| Glitch |
Not sure about all that, but it will weather proof your rain gear. | ||
| Redefine420 |
I can sell you some. Million mile oil changes. 20% increase in hp&tq. Not sure what a concho is, but yes, it will make everything 100% waterproof. no guarantees written or implied | ||
| Ft_bstrd |
I'll pour the snake oil on your leg and tell you it's raining. | ||
| Billyo |
OK. First test- I put 1oz of weight a little less than 90 degrees in front of the valve stem on the front wheel and took it out on the highway. The bike felt the same as it did before. I moved the weight a little more than 90 degrees behind the valve stem but will not be able to ride it until tomorrow. FWIW there were weights on both front and rear when the tires were changed out, although I don't remember how much. | ||
| Billyo |
Natexlh1000- 2oz front, 4oz rear. | ||
| Natexlh1000 |
I'd also like to as the forum here how much weight of an inbalance is needed to be able to feel it? | ||
| Billyo |
Test 2- I rode on the highway with the weights a little more than 90 degrees behind the valve stem. Then I stopped, took the weights off and continued riding. I haven't been able to detect any additional vibration with or without weights. Either the beads work as advertised or 1oz is not enough to feel a difference. Maybe someone who is ready to put new tires on could mount them unbalanced then, only if there is an imbalance, try the beads and see what they do. | ||
| Sifo |
I'd like to see someone with balance wheels add weight to unbalance them until they can tell a difference at 60 mph or so. Only then will you know how much weight you need to add to the Dynabead test to make sure you are within the margin of measurements. I would do it myself if I had weights laying around. Any volunteers? I have a somewhat open mind on this and would love to see some reasonably scientific testing done. Do snakes need to be oiled often? Maybe I should be oiling mine more?  | ||
| Billyo |
My wife had a pair of nice snakeskin boots that she never bothered oiling and the scales eventually flaked off and they cracked. Definitely keep your snaked well-oiled. |
