You asked for opinions....here's mine.
They are speed rated at 65MPH. Assuming they were broken in properly for their first 500 miles, never run over the speed rating, never bashed up against a curb or rock, were never overloaded and generally babied all their life, they're still nearing the end of their useful life as a tire.
I can almost assure you that if you didn't pick up you unit at the factory and bring it home yourself at 65mph, I guarantee your tires have been in excess of 70 mph being transported to the dealership all the way from the Elkhart, IN area.
That being said, to the OP, I had 3 marathon failures within the first 2.5 years from the tires stamped date. If you got 5 years out of yours, I'd say you're on borrowed time and much luckier than I.
