Dyna Beads - Do they work? If so, how?

Flaw #2
Once it is electrostatically deposited on the rim/wheel the dust is not mobile and cannot migrate around to the light spot.

Oh and Carver... https://www.fjrforum.com/forum//public/style_emoticons/default/****.gif

Mr. Fred, once again, my dear, you are mistaken!

The heavy and light spot remain stationary even with mass rotation.

That's one of the advantages of the 'Carver Balancing System', or CBS for short..

Once the dust settles in place, no more energy is wasted due to bead displacement with tire rotation initiation. In fact, the CBS ensures perfect balance until next tire change wash job, whatever comes first.

Geesh, and here I thought you and Ionbeam were fart smellers!

Edit - Almost forgot to add that the CBS is now on sale. 75 USD will get you 1.2 pounds of CarverBalancingDust, or CBD for short. This cost does NOT include postage, shipping, or handling. That's extra.

What if I call in the next 10 minutes?

CBD? Is that anything like angel magic pixie dust?

That second pic from ionbeam looks like a colonoscopy photo you really don't want to see if it's yours.

Oh, so it was tire polyps not rubber pearls?

You people are all missing the point. Since Dyna Beads are not connected to the tire gravity keeps the beads at the bottom of the tire. The weight of all those beads holds the tire to the road stopping it from vibrating. Ionbeam obviously buys inferior tires that are too rough on the inside causing too much friction which causes the beads to melt. To make Dyna Beads work even better you should sand the inside of your tires with 20000 grit sandpaper to reduce friction inside the tire to zero making sure that all the beads stay in the bottom where they belong.

I find Caver's claims highly suspect since he quotes a TUR of +/- 2u inch for his laser depth mic. Now if Caver had quoted +/- 2 µinches (microinches) I would have been impressed but u is defined as follows:

Also referred to as 1RU, although RU is not technically correct.

U is the standard unit of measure for designating the vertical usable space, or height of racks (metal frame designed to hold hardware devices) and cabinets (enclosures with one or more doors). This unit of measurement refers to the space between shelves on a rack. 1U is equal to 1.75 inches. For example, a rack designated as 20U, has 20 rack spaces for equipment and has 35 (20 x 1.75.) inches of vertical usable space. Rack and cabinet spaces and the equipment which fit into them are all measured in U.

Therefore doing the math we find 2u = 21.75 = 3.36 inches or roughly 3-3/8" . I don't need a laser to measure that, I can use a yardstick.

After forcing myself to read these 5 pages I think I will follow the excellent advice given by ionbeam. I will have a drink.

What have I learned? Mostly I just re-affirmed what I already knew. Mythbusters and DynaBeads are fine for some folks, but I am not spending either my money or my time on either.

OK, times up. Some time ago I wrote to Dyna Bead, using their "response usually in less than 24 hr" contact messaging asking for a more complete explanation of how the beads seek out the correct location to balance the tire. By this time I officially feel blown off. I didn't expect an answer but it was worth a try. Time for some new mental floss like "How does aspirin know where to go"; "Why do they sterilize the needle for a lethal injection" and, "If aliens exist, what kind of motorcycle would they ride and what kind of oil would they use".

I saw it in a show once.

You're thinking of anal beads you *******. From what Barry says, you've "seen" them more than once! Pervert!!

 

[Bustanut joker]

I never heard of 'em till I spent the weekend with Carver.

Sooo... Which of you guys got "balanced" with those beads? I am guessing it was neither centripetal or centrifugal force that was used to force the beads to the low spot?

Keep it up you three... Carver is gonna want pictures!

I've found them to work in one tire and not in another. But since I typically end up pulling nails & using sticky string to plug tires toward the end of their life, I just went back to lead because it's easy, there's no question about whether it'll work, and the beads stick to the rubber cement used to install the sticky string.

FJR Flyer is right, in that even dumping the beads is a PITA.

As to how they work, it's PFM. I tend to think the reason is probably centralization of mass, as Fred had in his putting mud in one edge of a frisbee. I do know from playing with tire dynes that tires are not perfectly round when we use them, which trashes a lot of these theories. Even the frisbee theory has a problem in that tires have a flat area of contact and right behind that is the rolling wave, shown below:

(Tire would be rolling clockwise as shown.)

As for the G450, higher tailwinds decrease the differential pressure that the starter and initial gas light off pressure can create. Starts that are both hot and hang can be REALLY expensive! And the tires will do a lot more than 195 its, but everybody should get to see when they do explode. It's REALLY impressive! Aircraft tire carcasses are many times thicker than used in cars and bikes, so when they fail it's a true explosion.

The problem with the Frisbee & mud is that the Frisbee is like the hub and not the tire. The mud is being flung off of the spinning disk, the beads are sitting on the bottom of the tire. As the tire starts to roll the beads will want to roll and stay down on the bottom of the tire until tire speed gets up to a point where friction start to draw the beads around the inside of the tire carcase.

And further more, what happens if the tire is filled with nitrogen :lol:
