Then ride that pressure for a dozen or so rides and see if it works for you. If you get pinch flats, then you need more pressure in the tire or you need to avoid the things that give you pinch flats. If you think you can do better, then adjust it up or down a few psi and ride that for a dozen or so rides. Check your legs and see how well they feel and check any metrics you might have from a cyclometer or GPS device.

Otherwise, what terrible disaster do you imagine is going to happen? Even at very high speeds I usually just come to a stop when a tire blows out. Perhaps on a fast down hill hairpin turn with a sheer cliff on one side it might be a concern.
