$155 a tire is an amazing deal!
My thoughts on the Wildpeak A/Ts...
The good: Their sidewalls are amazing. Arizona has some of the most brutal, jagged rocks out there and are known to cause sidewall failures all the time. These have held up with no issues at all and no slices in the sidewall. with the 14k miles I have on mine so far, there have been no chunking. They're quiet on the road and have decent grip on the rocks when aired down quit a bit. I did groove the Falkens earlier this year with a 3/8" blade. Seemed to help a lot in loose dirt.
The bad: I've had to replace 2 tires so far for being out of round. They constantly have to be rebalanced and still wobble somewhat. They're heavier than a Toyo MT (in the 315/75r16 size). Looks mild, but perform 100x better on the rocks than they look
You may get a good set of 4, but I will not be buying this tire ever again due to road manners. Many judge the tire by the looks and say it's terrible, but actually running the tire proves that it does grip very well on the rocks and their sidewalls are overbuilt
