High speed vibrations with Dyna Beads

[H96669]

Looks like we lost the OP 4 pages ago. I wonder if he took them beads off by now and either try riding without balancing or balanced with weights.

When I balance a wheel/tire assembly with weights, I KNOW it's in balance and can prove it.

When someone pours plastic beads in a tire, they HOPE it's in balance, but can't prove it.

Go to a pro race sometime and see if any of the factory tire busters use beads. They don't.

Ok.

Since I'm on the side of it didn't work for me. How do I get the beads out of the tube to keep from buying new ones?

Well ill jump in here for the heck of it. I run dynabeads on my Tiger. Used them in a set of kenda big blocks, 150/70-17, 110/80-19. I installed the recommended amount. I never had any vibrations of any kind even at speeds of 100mph. The set of big blocks went 5000 miles and am changing them now. Even wear patterns on both tires. All that with tubeless tires.

I used to race cars & can readily attest that "they" were not a collection of all the genius's in the world!
I've run the beads for a few years & have been getting normal wear & smooth riding. I reuse them, they're easy to install & not so complicated from there to say , why not? As to removing them from a tube w/o a knife, you've got me there...

Race car tires and wheels need to be dynamically balanced because of their width, and you can't use a simple static balance stand.

Might as well cut the tube open because new tires deserve new tubes anyway.

I've got two sets of tubes for my bike. The original tubes, 2004 bike, and a HD set I bought for spares. No problems in 40,000 miles...
I'm still running the original tubes in my Mtn. bike. It's a 1992 model.
Tubes don't disintegrate after one or two uses but if you feel they do I'll gladly send you my snail mail address and you can recycle them.

Dyna beads are stated to not work by the seller for wide/low profile tires. Many car tires these days are in that category. I remember them saying they don't disperse across the width properly for good balancing.

I was speaking towards balancing with weights, not beads.

I can balance a motorcycle wheel in 10 minutes using weights and see no need to screw around with plastic pellets that would take longer and make a mess the next time I had to break it down.

I really enjoy bead threads. They are ceramic, if "Dyna Beads" the air gun pellets are the plastic. As to making a mess, that's hardly the case as these pellets are very tiny-similar in size to maybe #12 shot like's in a .22 birdshot shell-definitely smaller than #9 shot,as an e.g.. I find it easy to recycle them. If I drop a few , no big deal & if your shop is like mine a stray ceramic bead thats around 1/32" in diameter won't cause much problem. I do dislike hunting for those stray bearing balls that escape from MC steering heads!
I reweigh what I catch(I dump them on a plastic scrap when changing tires) & use over. Takes little effort to lay there on a creeper & tap the clear plastic tube as they roll into the stem. My tires are smooth for the life of the tire, no matter the wear pattern.
