GOD, I love this club. I guess its true, you do learn something new everyday. The last rig(18 wheeler) I bought I used the Centramatic rings on my steer tires and there was a huge difference versus weight balancing. I've heard of the beads but didn't realize I could do the same thing when I go Darkside. I've never heard of the ride on though. I may go one way or the other when I do change over. I'll have to do more research on the beads or other ways before I change over.

IMO, it has all the advantages of beads, plus puncture protection.
