I finally went back to Goodyear after using those crappy Marathon's for too long and too many blowouts. I quit for about 5 years until the Endurance came out, and I gave them a couple of years to make sure I didn't hear any horror stories. Used Carlisle's for years before Marathons until they started falling apart. Did typical Chinesium tires for a few years, they were OK but they did not last long. Got Endurance on my enclosed trailer now and they have been flawless, but I have not had them on long so don't know longevity as of yet...
