They are made to balance any variation in rotation on the the tire, wheel, hub, even if you have mud or ice from offroading they will help keep you balanced for a safer trip home.
They are all drilled to specific bolt patterns and backspacing is not involved. 6x5.5 is available and I read that you can drill them to fit whatever you want.
I have found some good reviews on some dodge diesel forum and a couple others. Even with no tire balancing at all, they seem to work, but no one likes cost. However, 200 for a lifetime of tire/hub everything balanced better, not bad.
My apologies, I meant same principle. This one just uses high-density weights in oil as opposed to ceramic beads in the tire, but all differences aside, both products work by shifting weight in response to oscillations in the rotating assembly of the wheel, tire, and hub/rotor. As far as backspacing, I believe you are correct, that wouldn't have an effect on the design, but of course they would have to be drilled for our bolt pattern. I like the idea, but haven't had any problems with my tires or vibrations that a quick jaunt hasn't cleared up (mud or snow-related). I agree, however, that this is a good find and that it does remove some of the complications of using the tire to hold the shifting weights as opposed to a separate ring.
