Sailun Tire Failure
It was bound to happen, and it did. Any experts want to weigh in? Luckily, no damage to fifth wheel or rim. 2 year old Sailun S637 , inflated to 100 psi.

Very, very true that what applies to companies/individuals that put many thousands of miles on tires in a very short amount of time, doesn't necessarily apply to many RV'ers that age out a tire before it wears out.
"***Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of the tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load carrying capacity and minimize heat build-up***"
I wonder if this isn't a major CYA from Goodyear after those bad years with some of their tires.
Ford and Firestone certainly didn't pay attention to load ratings back in the 80s, when they killed and maimed a bunch of people by putting inadequate tires and inflations on Expeditions, and such. Really? A P tire on a 4-5k lb vehicle, then only inflate to 28 psi? Drop a load of kids and some gear into one and, guess what? You get blowouts at freeway speeds, rollovers, injuries and death. Morons...
