I have the centramatics and they do help a bit. I have never had the pleasure of seeing a tremendous improvement that others have. In the end I think the biggest factor in using these and getting maximum benefit is having a true set of rims and the tire itself. This is the real challenge, rims and tires. The won't fix an out of round tire (common problem) or a bent rim (common problem if you off-road on rock and/or use the steel rims)
