If you hear a "boom", the tire came off the rim.
Reading the OP, I can't tell if he's having blow offs. If the tube suddenly failed internally due just to melting, I don't see why you wouldn't get a popping noise as the pressure escaped out through the rim. Many would call that a "blow out".
The OP ought to relate whether the bead came off or not, and what the tube looked like.
