Dyna Beads -- Pictures and impressions

Well the pictures are below, and I'm not captioning them separately, but I think you'll get the picture, lol...

I measured a sample with my micrometer -- they measured from approximately 0.010" to 0.015" in diameter -- quite small.

I took photo in super-macro mode on my Formica faux-wood table top and you can see the underlying texture in the Formica, lol. You can also see that the beads appear quite spherical and fairly regular. This one appears to have some kind of dimple on it, but it's hard to tell just how deep it is. Overall they are very regular.

Here's some of the stuff I got. Two of the four bags of beads, each bag 8 ounce; the applicator bottle and tube which I've already loaded with 8 oz. of beads; the "filtered" tire valve inserts; and the "Alligator" valve caps.

This stuff is heavy! The bags feel surpisingly weighty. I believe their claim that these are denser than steel.

After I get a chance to put them in, I'll post on the experience.

Might do a couple tonight. Big time killer is refilling my tires with the "TruckAir" compressor. Even though it's better than most portable 12 volt compressors, it still takes like 15 minutes to fill a 35" tire.

Click above and read about them. You can also find info about them on the internet in general. I'm short of recommending them -- I've just become convinced enough to try them myself.

seeing that reminds me of a guy that came into the dealership when i worked there. he brought in small packages of graphite and asked us to put them in the tires. said he dove over mesquite branches all day and it kept small punctures from leaking. anyone know what it was called or where to get it?

can you just swap out the valve? or is it just the inside part of the valve?

Unscrew the old valve, pop in the new one. It's the valve core.

I used to run them. I'm seriosuly considering it again. As of right now, my ride is pretty perfect, but I got a little steering wheel shimmy (I just had alignment done, and it is set perfect to fact. specs) so after I get boggers, I may try them.


I highly reccomend a mixture of BOTH the beads and conventional. That was the best results for me.

I tried just lead weights, they were OK, I still got a 40mph bounce (with old rims), I tried just beads, I had a worse 40mph bounce, but a better overall ride. At 80mph it was smooth. Then I tried the beads/conventional, and for the 5 minutes the pound on weights stayed on, it was great!!! No vibration, no bounce, ,nothing....



So I may try them for the boggers, I dunno yet...we'll see.



I would only run them if you have problems balancing your tires. They can be weird around highway onramps (low speed corners also) because it "shifts" all the beads to one side, then when you accellerate, all the beads stay on one side, and you shake/shimmy/wobble. Thats the major negative about them. They are g force sensitive. And I don't drive like an F1 driver either...

Well, the valve question was answered, lol.

Even with these new tires, I have noticed a mid speed "wave" in the hum of the tires. Basically, what I've always had at certain speeds around 30-40 mph is a whoom..hum..whoom..hum type thing at a rate of a few hertz. The hum swelled up and down.

With the wheel weights nicely balanced on the MTZ's, I still had it, though much less. With the beads added in, the hum is steady! Very interesting result.

Overall ride appears unchanged -- so they didn't hurt anything. But I already reported in another thread that the MTZ's plus the balancing job the tire shop did are very good. The ride was already smooth so it's hard to tell if it's smoother yet or not.

Not really concerned so much about smooth as about long term tire wear. That's why I got these and I'm hoping for the best.

Whatever results I'm getting, this is just with the front done. I have yet to do the rear.

The alligator valve caps make the stems kind of long. I'm not sure if I like that or not. We'll see. They were only $4 for all of them though, so no big deal.

Probably not to sound -- but they should to the wear of the tires over time, and I'll need them in for when I rotate the tires.

Sorry to bring up a week old thread, but any new updates?

I just ordered 4 8oz bags..again.

Hopefully I'll have em in soon, I'm getting that woo wooo woo sound on the hwy. I wasn't getting it when I first got the tires balanced, they seem like they are wearing a little strange, so I am throwing the beads in. I'll try em out..

I've got them all in and all is smooth and quiet -- for mud tires, lol. Really, we'll only know after I run these for awhile and since these are a tire I haven't run before, what will we know?

I'm stepping out in "faith" here, lol. One thing I'm looking for less of is cupping type stuff and what not since that brings the noise level up big time.

Sorry to only be able to offer impressions -- this is something that's really hard to measure. But it wasn't a lot of money, so no big deal if they aren't a "miracle". Hoping for better wear over time though.

I hear ya!

As far as my experience w/ them, I ran them under control.

I ran just lead weights, that was nearly perfect, except they fell off after 2 mins of hwy driving

I ran no weights at all, that STANK bad!

I ran weights and beads, that was OK becasue the balancing was majorly off

I ran no weights and just beads, it was OK, I had a 40 bounce and a 60mph and up shake, but it was good for the situation.

I have the inconsistent sound in my tires now, I'm hoping for that to go away after the beads. I'll be keeping these tires for a little while (until the new ones) so I want them to at least ride perfect for the time being.

They were pretty cheap (the beads), so like you said, I'm not expecting a miracle.

About $50 for four tires, including the valves and so forth. Not much more than having the tires balanced one time, except that it keeps them balanced. I just wasn't getting mine rebalanced after offroading and losing weights, so it seemed like a good deal.

x2, except mine still need a little tweaking from the balance job I got...

Mine were $59 after shipping. I bought 4 8oz bags and 4 valve stems.

Dont mean to bring up a old thread but i installed eight ounce bags in my 33 bfgs and the vibration is worse than it was with no weights installed. I am super pissed as it took some time to get the stuff into the tires via the applicator. I have an email into the company to see what they have to say.

any chance there was some moisture in the tires Bill?
were the beads about the same temperature as the rims and tires when you put them in?

They won't clump with moisture. I'm sorry to hear about your vibration. Mine are still running smooth.

Dynabeads will not make up for lateral imbalance. If the inboard vs. outboard balance is not good, I can see how they might not help, and for all I know they could be worse.

What kind of tires are they, Bill? Are they a brand known for balancing quirks like Interco or anything?
