Tread separation and sidewall "blowout" are two completely different failures with completely different causes.
Checking the air in your tires every couple of hours is about as useful as removing the gauges from your instrument panel on the TV and checking the dip stick oil level every few hours. We have not had the technology available to monitor tire inflation until about 15 years ago. If you don't think TPMS is a good thing then I would challenge you to tell me how you would feel if we were to remove all your engine instruments.
Almost all sidewall "blowouts" are actually run low flex failures.
is a detailed analysis with lots of pictures. I find it interesting that even after doing the analysis and telling the owner to get a TPMS he did not follow my suggestion. Guess what, he has had another similar failure.
Tread Separations can many times be detected before the tire comes apart if a thorough inspection is done.
Here is a video showing the out of round tire.

Here is a post
on the analysis of the tire seen in the video with links with more info and details than most want to know.
The facts and science are out there and available on many RV forums on how to avoid or at least minimize the costs and inconvenience of tire failures.
There are at least two tire engineers who are following a number of forums. Tire Engineering and tire failure analysis is a VERY specialized aspect of Engineering with only a handful of fully competent tire forensic engineers in the world. It takes decades and thousands of tire autopsies to become proficient in determining the real cause
of a tire failure.
Simply changing brand or size or load range or country of manufacture is of no value if those features are not the real cause of the failure.
This would be like changing the brand gasoline used if the TV really was supposed to use diesel fuel.
