"Internal balance media". Guys at the shop were raving about how well it worked, so I did a search on "tire balance", and was amazed. When I took my new tires and mags for M/Balance, I mentioned it, and the guy said, "Oh yea, 'balance bag', thats $5 per wheel more." On the 'spin balancer' they checked out perfect. This is going to be an embarassing thread if everybody does it this way and I'm the last to know about this, as usual. How about it???

No worry about embarassment , I've never seen it before. But what a great concept, It sounds like it would be self correcting in situations of mud or somthing stuck to the wheel.

I just had them done on my 04 Durango with 20" Rims, it works out great since as long as you have the tires on the same rims you never need to balance them, just rotate. I paid about $7.50 per tire but I won't need to do it again so it works out great.
The ride is excellent, I recommend the sand bags!!
Go read in the Off-Road forum here. A lot of the guys there put bb's in their tires. Sounds like a good idea and like it actually works. I may try it out sometime.
A guy at the shop had huge off-road type tires on a 3/4 ton Dodge. He said at about 45 up the steering wheel would shake bad. We had a couple jars of air-soft plastic BB's. We broke the tires down and put some in each tire, about 1/2 a jar each, (apparently you can't put too many in) then he took it for a drive and no shake, even at 70 MPH. Apparently they have been doing this to 18 wheelers for a long time. It seems that several types of media are used. BB's, plastic *****, ceramic *****, crushed shirt buttons, etc......

It works out great until you get mositure in the tire, then it clumps and won't work anymore. Did the shop tell you that you are supposed to have a line drier on your air hose when you fill the tire?

I had read about that in the Off-Road forum. I think that's why they use bb's, so they can't clump together. I think they used the copper bb's and not the plastic ones although it could be either. It was some interesting reading when the topic was up.
Yeah, I think the clumping is bad. You can get an in-line drier for cheap. They are packed with the dessicant (stuff that absorbs water) beads. I have made my own in the past for my shop air. I took an oil/water filter and filled the cannister with dessicant beads. I bought a jar of these from HomeDepot in the plumbing section. They are used to remove humidity from the air.
Buying this stuff in the plumbing section they where really cheap. If you buy a line dryer from a tire shop or 4x4 shop it was really expensive.
I remember there was a segment about this stuff on the "Trucks" TV show. Tracey even addressed the moisture issue. Check out the manufacture's website and see what it says.
What is the theory of how the bb's, bags, etc. work? My understanding is that they are not physically attached but loose in the tire.

Scott, the media is loose in the tire. From what I've read, there is not much effect under 20 mph, then the media finds the lighest spot and C-force keeps it there, rebalancing the tire every time you take off. Try a search on "tire balance".
