Anyone used dyna beads?

Golf balls in tractor trailer tires comes to mind. The beads are much better than golfballs.

The thing that nobody seems to have mentioned, and probably the most vital part of any 'dynamic balancer' like dynabeads or balancing fluid is the tire has to be in contact with the road for it all to work. The heavy part of the tire will pull the tire UP off the road as it comes to the top of the rotation, this shakes the dynamic balancer DOWN towards the lighter side and balances the tire.
That's why you probably won't see it work on a balancing machine, they're too rigid and the balancing medium can't get moved where it needs to go.

Inertia, centripetal force, gyroscopic precession, suspension dynamics, et.c, et.c, et.c...

I will be installing dyna beads when I replace the tires on my 1200 Sportster Custom. Hope they work, 'cause wheel weights are ugly.

You have a demo right in your home and can make up a test for dynamic balancing. Dynamic balancing is well known (not to a few on this forum) and proven for many years. The washing machine in your home almost certainly uses water at the base of the drum to dynamically balance the load during a spin cycle.

Use a couple of tubes half full of water around the rim for a home made dynamic balancing device.

I picked up the dyna beads and squirted them in for my build; $11 with applicator bottle really can't be beat.

I mount my own tires, and have never balanced one yet.

I ran Dyna beads on my BMW F800 dual sport. Put the beads in the tube, 1 small bag in the front and 1 large in the back. ( they are sold as a set, 2 bags, the applicator and instructions.)
I would suggest they work well and would use them again, however I prefer static balance, as I have a friend who made his own balancer, so it's free.

Never used either the media in a tire, or centramatic balancers behind one, on a bike. However I have used both on my Jeep.

I run stock military Hummer 12 bolt 2piece beadlocks with 7.5" back spacing and 42" tires on the Heep. Trying to balance those tires is a huge PITA. Plus trying to keep weights on the rims is impossible offroad. They ALWAYS get peeled off on the trail. Trying to drive a light weight vehicle with unbalanced 42" tires at highway speeds is just dangerous.

I got a set of Centramatic balancers for the tires, but I cant fit them on my front wheels. I installed them on the rear though. I also used standard BB's in the front tires. The balance was worlds different! I did have to add BB's to the rear tires as the Centramatics werent enough. If crawlers can get 42"+ tires and heavy 2 piece steel wheels +PVC beadlock inserts to balance out, why would it not work on tiny motorcycle tires?

Using centrifugal force to balance tires has been proven to work by Hummers, Off roaders, and truckers, many times over, for many thousands of miles.

I know the guys on the raider forum swore by dyno beads until they found a new product that worked even better. Its a liquid gel like stuff that also seals punctures but never actually turns to a solid in the tire (unlike that crappy slime stuff for bikes). Tejas motorsports sells it.
