I installed the Centramatics on my rear axle a few years ago. My coach came with the Goodyear G670 tires which I later learned to hate due to separations and rivering on the front tires. At 40000 miles I changed out my original rear tires with new GoodYears and added the Centramatics. The Goodyear's I took off of the rear were not bad, but had some odd tire wear on each tire. I now have about 15000 miles on the rear tires and all four are wearing perfectly. I have to attribute this to the Centramatic.
After replacing the rears, I got another year out of the front GoodYears that I had already replaced twice. This time I went with the Hankooks on the front and tried balancing beads for the first time. The Hankooks are wonderful 10000 miles later and are wearing perfectly.
I like the Centramatics on the rear and will never have to balance them again. I don't know if I would pay for the Centramatics on the front because the beads have worked so well.
