As to the 5 bar / 73psi, that comes directly from ETRTO. So essentially the absolute do not exceed limit of hookless on any size tire is 5 bar / 73psi or lower if dictated by the manufacturer.
I'd love to get the current ERTRO standards handbook but it's 150 €, so a bit too steep just for wanting to know a few things.
False. I had a pair of hookless Giant SLR-1 wheels on my previous race bike and they had a maximum pressure limit way above 73psi. It was 125psi if I recall properly. Most manufacturer, however, have a maximum pressure of 5 bars.
