Weird about the BFG A/T being on backorder, I just picked up a brand new set at discount 2 weeks ago and they had a whole bunch sitting right there. Anyway, I don't have much experience in other tires, but I can tell you that my dad's rubi is sitting on 32" BFG A/T's and he has close to 60k miles on them and they look great. They're a little noisy now from being worn, but still ride fine with no vibrations. I have no complaints about mine either.
