…… A hypothetical for the new GY Endurance ST brand could include a collaboration between GY & RVIA. The Endurance came on the market about the same time RVIA made the now enacted recommendation for all member RV trailer manufacturers to provide 10% in load capacity reserves above vehicle certified GAWRs for all tire fitments. ……
Interesting, but it doesn't explain why the older trailers also are not experiencing these failures. Nevertheless, the 10% change was something that needed to be done to bring the RV industry in line with cars and trucks.

I don't think it's the sidewalls that are important here. It's the cap plies in the tread area. The Marathons didn't have them and the Endurance ST's do.
My experience says that cap plies are a great help. Aside from improving the speed capability, they also increase the load carrying capability. That's why the Endurance series has an
N speed rating, instead of the no speed rating for the Marathon's (and L speed rating for the 2015 production onward).
