I've only had my new Jayco 23RB for about a year and 1/2 so far, having bought it in June of 2017. Jayco, at the time, had just changed over from installing China made TT tires, which were load range C, and installing the newly designed and manufactured Goodyear Endurance. Jayco did this in the middle of the manufacturing year.
Now to the point. I've already put over 14,000 miles on this new trailer, including a trip this spring/summer from Virginia, to Florida, to the 4 Corners region, to Utah, Idaho, Wyoming, Montana, South Dakota to Michigan and back to Virginia.
The Endurance have performed wonderfully, so far, and show little to no wear. I had two flats during the trip, but both were from nails. I've had to replace one of the Endurance tires, but this was because I snagged the sidewall on the end of a car carrier dolly. Tire didn't go flat, but the sidewall was damaged so it had to be replaced.
So far, I'm well pleased with the Endurance tire. It's a ST205/75R15 LRE D size. The next few years will tell the tale on the endurance of the Endurance tire.
