Hi Old Dude 66,
I've been running Centramatics on all wheels. Centramatics is an excellent product. They work as advertised and I would purchase them again. My tires have 92K miles on them. They are wearing superbly even side to side and all around the tire. Side walls are in excellent condition. The tires will be replaced in 2015 because of Michelin's 10 year limitation.
