Yes they were the original G614's. I haven't calculated the number of miles on them yet but they are the originals so they are at least 3 years old. I replaced them with a new set of four G614's. I have been impressed with the way Goodyear stands behind their tires when problems occur.
There was a little damage to the underside of the trailer on the passenger side. Some of the belly fabric in the wheel well was ripped out and will have to be replaced. Nothing structural or cosmetic anyway.
As an aside. If you have problems on the road and want Goodyear service, call customer service and ask for the nearest commercial tire location. They are the ones who will most likely have the G614's. And, many of them will do onsite tire replacement for a reasonable fee.
