I put a set of Treadwrights on my GMC, whatever their BFG A/T knockoff is. I've had a shake that no tire shop seems to be able to get rid of, IF I find a shop that's even willing to touch them. I went to about 6 before I found a local chain that begrudgingly agreed to put them on. I'm pretty sure they instituted a policy that they wouldn't touch them as well after me because of the trouble they had.
Even before they tried he said he was weary of the retreads because they couldn't tell the age of the casing, and the rubber might be super hard and stiff. Which turned out to be the case with mine, and the inner bead ripped itself off after trying to install the tire and they had to send it out to do a bead repair. Then had to wait for that to be done and then had to wait another day for their "expert tire mounter" to come in and still had to be real careful with them as the others started ripping too, but not to the extent the previous attempt was made.
As for the shake, They either flat spot REAL easy or have a hump, because it kinda goes away after you drive it for an hour, but it comes right back after you park it for a week or two. No shop has been able to get rid of it. And I can't determine which tire it is for any kind of warranty regardless of how much I move them around on the truck, it might be two of them or all of them to a certain extent.
In the end he said he could have sold me a set of Kelly A/T's for about the same price. I'm almost certain they would have been of better quality.
Between the time, gas and money spent trying to find a shop, and the lack luster performance, I'd have to say I'd recommend looking for a deal or a sale on standard or even off brand tires before going to a re-tread.
