I bought a set of Treadwright Warden load E retreads in 265/70/R17 8-9 years ago for my old '85 F-250 that was driven infrequently.
I liked their spiel about "good for planet, made in USA", also they had the walnut shell option which helped traction in adverse winter conditions (I lived in Colo at the time). I could have bought a new set of nice Cooper or other mid-range A/T tires for less than $100 more. But the tread pattern was very similar to the BFG K/02, which indeed was a lot more money. So I tried them.
200-300 miles later, I had a tread separation while doing 65-70mph which beat up the bed / rear fender above the tire pretty good and left nothing but the old carcass, which unbelievably still held air and allowed me to get home. The $1K+ body damage wasn't worth the $100 saved, I can tell you that.
Adding insult to injury, Treadwrights customer service was less than stellar. After several back-and-forth E-mails, they took their time getting me a replacement, which finally did arrive. Good thing this wasn't a daily driver. However, the replacement had visible holes in the sidewall where you could see the carcass underneath (this was a bead to bead remold). I took photos which I sent to them, and they sent ANOTHER replacement tire (let me keep the defective one which cost me money to recycle). After all that, they seemed to perform adequately.
But the experience completely soured my taste for retread/remold tires. Which is unfortunate because my parents always used studded retreads for winter tires in VT for our family car when I was a kid, and had nothing but good luck with them.
