I don't know where the very silly numbers on some fatter tyres come from.
rgds, sreten.
For an average rider 60 to 65 psi rear and 50 to 55 psi front is ballpark for 38mm.
Just because other tires have a lower rating is irrelevant. Just because a higher pressure may be unnecessary is irrelevant as well, because 75-100 psi has been approved by the manufacturer of the tire. Regardless, the tire should be able to hold much more pressure. That the tube exploded probably had very little to do with the high pressure; it is just as likely to have exploded at 65 psi.
