I have spent a lot of time searching and reading papers and have yet to read anything linked directly to hyperinflation related tire failures. I haven't seen any security warning with explanations or mention of accidents specifically due to hyperinflation anywhere.
I have found 2 studies related to grip, handling and comfort vs pressure and load. They don't go in the hyperinflation zone unfortunately.
