Anyone ever use this stuff?
I did a forum search and came up with nothing.

Thanks in advance.

They work well for me.  I transferred them when I put on new tires and tubes.  Do be sure you check the air only with the tire valve rotated somewhere toward the upper part of the wheel.  By the way, they went into my new rear tube with the 90° bent stem slowly but did go in.  To get them into any valve stem, take your time and continuously tap the stem with something heavy--I used a #3 Phillips screwdriver shank to tap with.

  If your tire was balanced and you put them in how would you know it was better.

I'm saying that the beads themselves will create an imbalance by settling at the bottom of the tire at a stop... if this coincides with a natural imbalance in the tire, there will be double the effect, whether you perceive it or not...
Enough beads to create a balance will be enough to create an imbalance...

Why not just balance your tire properly to start with?...

Definitely don't use "Slime" with the beads...

Can you get condensation in a tire?... I'm not sure about that one... Avoid airing your tires on humid days?....

It's just a clever gimmick,... if the logic of the gimmick appeals,... you'll buy it.
like those gas saving magnets and what-not...
The good news is, this will have more effect than the magnets,... the bad is, this will have more effect than the magnets....

Here's a link to a truck balancer rig using the same techniques:

Moisture inside the tire doesn't matter with the balancing beads...unless its frozen.  Large amounts of oil from a compressor will gum up the works.

Conventional spin balancing is great.  The Dyna Beads can be re-used in the next tire and the next to avoid additional expense.  All we have to do is save the old tube, cut it open, and transfer the beads (or re-use the tube if it's good).

Thanks for all the responses; I ordered them and will let you guys know how it turns out. They will be installed in new tube tires front and back.

Dyna beads were discussed at length here long ago.  The general consensus at that time, and research of the Internet for comments by users, was a split decision.  Some said the beads worked only at high speed, some said they didn't work at all and some said they worked.  Seems to me there are unidentified variables involved here.  Myself I didn't spend the $ on them because too many people reported that they didn't work, and I wasn't about to gamble with my money.  If I bought them and they didn't work for me, then I'd have to pay for traditional  balancing anyway.

  Years ago when I use to put on alot of miles on, I changed a lot of tires,I left the old weights on and never balance the new ones and never felt them being out of balance,Course I was never driving at high speeds like over 75 miles an hour.
