A cause for tire blowouts?

I was on the I-69 the other day, tooling along at my typical 71/72 mph. I had 2 trucks pass me pulling trailers that were obviously being delivered (DOT markings on the trucks, etc). They just eased by me, but must have been doing about 74/75 mph.

This was not the first time this has happened, but it got me wondering.

Are these 65mph tires being damaged during transport. People say their new trailer was properly aired, not overloaded, not speeding, yet they have a blowout. Were their tires damaged, a time bomb, from the day they picked it up from the dealer?

Good point Winged One. Those trailers being delivered are at their lightest, not that I'm trying to defend those transporters but they might have that in mind. More likely though they simply don't give a Sh**, just get it to the dealership, sign off on it and get back to get another one, keep the money flowing. Once the transporter delivers the goods it's not HIS problem any more.
