I checked the pressure last week an hour before it blew, it was right on 50.
'blew' is a very generic term. Could have been a road hazard that reduced pressure until the tire over heated and let go. Then the tire is shredded beyond recognition so the cause is not found.
Couple weeks ago I picked up a screw. I was lucky to notice a bit of tire bulge at a fuel stop. Pressure was down from 65 to 35 in just a few hours. Another couple hours and the whole tire could have 'blew' with no fault of the tire.
And yes I have had a tread come off and another with the tread separating ready to come off. Both still holding full pressure and obvious poor quality tire.
