Happy to hear you were able to maintain control and no one was injured.
I had this happen about 10 years ago with just about the same results - no loss of control, damaged line to the air bag, $5,000 of damage to the truck and an absolutely shredded tire. The term "tread separation" is far too subtle, because these high pressure tires pretty much explode when they fail (at least at freeway speed).
Based on my research after the incident, it sounds like there is no way to detect when a seemingly road worthy tire will fail. I'd be curious to know what others have learned and if there are any new high-tech ways to detect a potential failure before it occurs.
