Centramatic balancers were installed on my 2007 Goldwing prior to a 12,000 mile trip through 36 states in June/July of 2013. A new Bridgestone front tire was installed at the same time and the rear Bridgestone tire had about 3500 mile on it. I immediately felt improvement in the ride with reduced wobble in the front at low speed. Currently have 15,395 miles on the front tire with barley discernible cupping wear on the left side of the front tire. I should be able to get at least 3,000 or more miles of use on the front tire before worn down to the wear bars. The rear tire was replaced shortly after completion of the 12000 mile trip. Wear on the rear tire was even with very little cupping but down to the wear bars in the center of the tread. I was pulling a trailer for the entire trip and was two up for the last 3500 miles.
