I brought this exact topic on another forum and most thought the beads where unnecessary/ snake oil. I'm still on the fence about the whole topic. Going 37" tires and having to balance them every 3-4k miles seems to be a drainer. But I did not know there are different sizes of Dyna beads. I'll have to look this up.

 

I have been running them on mine for the past 13000 miles. Don't recall a difference in sizes but it has been a while. I have never had any issues with them and will utilize them in the future. They make balancing a lot easier, especially for bead-locked wheels.

 

Had them in my AEV Pintler bead locks w/ 37" BFG Mud tires and had a problem once in a while. Had to once in awhile slow down to a stop and take off again. This was after a sharp slow corner, they wouldn't set right. But for the majority of the time I was happy with them. I took them out and put them into my Walker Evens bead locks using same tire as on AEV's and they would not balance. Had to take them out and have them Road Force balanced w/ stick on weights.

 

Seems that some people enjoy them and some really have some problems. Wondering if its the one manufacture from the other???
