I haven't kept up with the trucking laws in quite a few years, but the last I knew it was illegal to run retreads on the front axle of the 18-wheelers. So it's very likely that a blown front tire on an 18-wheeler was NOT a retread. Yep, tires that are not retreads have actually been known to blow out on both cars and trucks. But yes, I know a trucker could have violated that law, but I haven't personally seen one do that. I once had a right rear tire on a 1956 Mercury blow out when I was doing more than 100 mph. I also had a left front tire blow out doing more than 100 mph on a 1966 Chevrolet police sedan. No power steering on either of those vehicles, neither had retread tires, neither had worn out tread, and neither resulted in any kind of accident or loss of control, so blaming accidents on retread tires without doing a proper investigation is nonsense. But since all retreads are junk (according to Btown), I just don't understand how Bandag has been able to keep selling them to trucking companies for more than 50 years. If an accident occurs as bad as Btown is talking about, the police (state or local) should have had an accident investigation specialist to determine the exact cause. Of course the cause MAY very well have been a blown front tire, and that tire MAY or MAY NOT have been a retread. And of course it's been about 43 years since I graduated from the Northwestern University Traffic Institute's Long Course (9 months), and it's been about 23 years since I worked in a tire dealership, so some of my knowledge is admittedly dated.
I'm sorry to offend you. I have never had a problem with virgin tires on any of my vehicles but a friend of mine with less then 5,000 miles on recaps had a 16.666% failure rate. The tires were not low or high on air pressure. We will wait and see how the other 5 last. Could be another 80,000 miles. Who knows.
