China Bombs Got Me
I have read many posts about the poor quality of tires RV manufacturers are putting on new RV's. Well these tires (the infamous Tow Max Power King) blew on my 5er causing damage. I always check for p...

That is some stretch of logic. Post hoc ergo propter hoc. FWIW it isn't obvious that a tire's speed rating is inversely related to its load rating. You've drawn that conclusion, but there's no reasons given to prove it's validity. Saying so does not make it so.
Also the test you show says the 24-hour test is at 100% Load Capacity not a specific weight. So the 100% Load Capacity for an ST tire would 3400 lbs, not 3000 lbs. Still think that an ST tire could survive that? I don't.
First, the point about speed vs load: The yearbooks published by the Tire and Rim Association have many references to the phenomenon. At the beginning of the section on LT tires, there's a table showing how to recalculate the maximum load for various speeds.
So, No, I am not making this up.
Second, if we are trying to compare tires, we need to get to an apples to apples comparison - and using the same "size" is a way to do that. This is particularly appropriate in that many people are replacing ST tires with LT tires of about the same size. They would use the same size if they could.
So what I am trying to do is explore that. The fact that the rated load is different and the way the loads are rated are different is something that has to be dealt with appropriately.
