Thank you for taking the time to read the thread and post a response. I love the GT500's and would really like to have one but it is not practical for me right now. It is also funny you mentioned your 66 Mustang because now that the Jeep is almost done, I have found myself searching CL for early Mustang projects. Not sure if I want to dive into another restoration but if I found the right deal I might consider it.

Thanks Calvin. I'm probably several weeks away from diving into this but I'm sure I'll post about it after I install some.

Thank you. It is a little more unique than what I had originally planned but I loved the way it turned out and have a great sense of satisfaction while driving it.

New tires are going to be 33x12.5x15 BFG KM2's. I'm going on vacation for a couple days so I will order them when I get back. Don't want them shipped while I'm not here.

I also plan to use DYNA Beads as a weight solution. I have never personally used them but they are supposed to work. It will keep me from having to use the massive wheel weights you typically need for the larger tires.

The Dyna-Beads sound interesting. I've never heard of them before. I don't understand the physics that would cause them to evenly distribute throughout the tire, or how they can react quickly enough to offset vibrations. You will be a good test case for everybody! Won't they be noisy when stopping and starting, clacking together inside the tire?

It is a little weird how they work. Here is a decent attempt at explaining it and lets you "see" them in action.
I'm not sure about being able to hear them inside the tire.

Actually now that I have been trying to find a good source for them I might bail on the idea. The best pricing I have found would be right at $100 for the 40oz of beads it would take for five tires. That is a little pricy.

I know this is naive, but couldn't you emulate the Dyna-Beads with small ball bearings or something? I don't know what kind of weight they would have to be, but a ball is a ball! And a ball rolling around on the inside of a spinning tire would act the same. I would look into the weight issue of the balls. Just a thought... as you slow and balls come out of rotation, they will likely hit the wheel on the inside of the tire and make some racket!

I would think that you could get the same results with lead shot. Just cut open a few 12 gauge shells.

I wouldn't have any problem paying this guy for his invention and patent. My tires stay balanced though.

IIRC, I've read on Pirate that some people actually use the plastic bb's from air-sof (sp?) guns. I too was curious how they would actually provide balance for a large tire - so thanks for posting the youtube clip Mike!

You don't want anything that will rust, inside the tire.
I have the plastic beads ( air-soft) from wally world in a set of 33-13.50-15, LTB,bias ply. They work great. Also have two other friends that use them, with good results, up to at least 60/65 mph. There is a chart somewhere, but I'm on my phone, and don't know to post a link.
Google, inovativebalanceing (sp)

IIRC, I used 3 bottles for the four tires. One of the friends used 1 bottle per tire. ( 38" x 16.5 ) on recentered h1 headlocks

I had the beads in my 35" tires on my TJ for a while and was not happy with them. If you hit a bump at road speeds it will knock the beads out and take a minute for them to recalibrate themselves. I also had a bad wobble at 55 to 65 mph with them. I had the beads removed and the tires balanced with weights and the issues went away. I am unsure if CJ leafs are 2.5" wide or not but here is where I bought my shims and they come with centerpins. http://www.ironrockoffroad.com/Merch...egory_Code=PFX

There small ceramic beads. I doubt they would wear the tire much. How would they sell a product that destroys your tire?

Curious to see what you do here. I've toyed with the idea of using air soft pellets to balance once I finally get 35s, but have read mixed reviews of bead balancing. Just heard of road force balancing which sounds promising. Back to researching...

Absolutely you can use other stuff. I use Daisy BBs. I've also usd airsoft beads. Either works, EXTREMELY well.

Anyone that pays the price for Dynabeads... isn't thinking.

I have also used Centramatic balancers with great success. I have them on the wife's Jeep. $200 for a set of 4- and yes, that's expensive... but I don't have to hear anything from the wife when it comes time to getting new tires. The last set of tires I put on her Jeep, I had 12 ounces of BBs in each wheel, and the "professional" at the tire store went on at length about how stupid that is. She believed him instead of me... after all, he's "the professional"...

.. well, apparently he missed "balance day" at the "tire university", because this is the EXACT same sort of thing that 18 wheelers use to balance their tires, as well as other large tire users (airlines).

Some folks will be concerned about the BBs abrading the tire carcass or the wheel. This is FUD. (Fear, Uncertainty, and Doubt) I have run these on several vehicles ranging from my motorcycle to 37" tires that "couldn't be balanced" on a friend's Hummer. NO problems. The only change I noted was the copper cladding on the BBs was removed. BFD!

90XJ: Custom body armor, HF/MM 8000# winch, ORGS SBS braces, custom exhaust, 4X4 Posilok, Big-O MT's in 33X12.5X15, 6" hybrid lift, Clayton's longarms, JKS discos, liberal fender-chopping with Bushwackers, Rancho 99012 and 99264's.

89 S-10 Blazer: new engine, Vette 700R4 tranny, rebuilt NP231C tcase. Soon will get front and rear Dana 44's

94 ZJ: stock for now. Wife wants 4" lift and 33's... and will never go offroad. WTF, over?

I'm still on the fence about using the Dynabeeds or similar balancing solutions. Having read a lot of information it sounds like they are not a cure all for tire balancing as you still might have to use standard wheel weights to get a complete balance.
