I have bought and used them. I would not buy again.
They are fine at highway speeds and much better than old-school retreads.
Two issues keep me from buying again:
1. Their stock in retread tires is dependent on acquiring proper sized old tires toe re-manufacture. So, what you want may not be available. For months.
2. Warranty is such that if the new tread busts in 2 years, THEY replace it. If the old part of the tire busts or the new tread comes loose YOU eat the cost.
I had both issues, went through 6 tires, 2 went bad. One bad tire (tread cracking) replaced by TW--actually had to get 2 because my exact tire size not available. One bad tire I ate (retread separation from donor tire).
Cost-wise, it came out the same as buying the cheapest brand new AT truck tires from Discount tires, Nitto. This latter bit is much less hassle, so I won;t buy Treadwrights again, unless some circumstance makes them the smart play: super hard-use eats tires in less than 2 years oand lots of trucks maybe.
