TUFO tubular-clincher caution - Cycling Mob: Road Cycling, Mountain Biking and More

I recently installed the TUFO Prestige Cyclocross tubular-clinchers. I
had read that they could be run at lower pressure than clinchers
without fear of a pinch flat. Since the max pressure on these is 65
psi, I aired them down by increments until I was at 30 lbs on the
front tire, 40 on the rear. This didn't seem especially low, but while
turning a corner on pavement at around 20 mph, the front tire came off
the rim, dumping me hard. I have since looked for recommended minimum
pressure on these tires, but I haven't found any. Any recommendations
on minimum pressure from experience? Obviously, for me it is higher
than 30 psi. So what good are these tires if they have to stay pumped
up as high or higher than clinchers?
