The fleet of semi's we have used to use retread super singles. The life of the retread was shorter than the life of a new tire, so they went back to using new only. They use a Michelin tire also.
I would not run a retread on my truck. Piece of mind is something you can not put a price tag on. I spent to much money on my truck to put a questionable product like a retread tire on it. I have a heavy right foot so getting a flat at speed is not something I want to deal with.
Now if I had farm trucks as @grampy does that would be a different story. No highhway speeds and trail use only than it seems like a wise business choice.
