I have always had BFG all terrains with no problems. Last time I needed tires I went with nitto dura grapplers for the extra capacity. They only lasted 35k miles and were worn down. The dealer I bought them from would not rotate them anymore (Americas tire). They were rotated every 5k miles by the dealer. The dealer gave me $50 off a tire because they had some dry rot also. They did ride nice and wore evenly but wore down to fast for my liking. I went back to BFG all terrains as the lowest miles I had out of any pairs I had was 50k.
The dealer said they had been having dry rot issues with the dura, dune and terra grapplers.
