We lost a tag axle tire. I heard a noise as the tread tore up the rear quarter panel and the exhaust. Stopped right away. I had checked the pressure just before we hit the road. When the tire shop pulled off the tire I checked the pressure again and it was correct. Just the tread had departed. The tire was 7 years old.
Even though the tire still held pressure, most likely you would have known of the pending problem before the tread departed as there would have been heat buildup before it came apart.
