I replaced my BFGoodrich MT T/A tires on my Wrangler with Hankook AT2 Extreme's, and what a difference. I'm 8,000 miles in on the AT2's, and there is zero sign of wear. My wife's mind was blown that our jeep was so much quieter, and we could have a conversation at highway speed without having to yell over the tire noise. These things are practically silent.
The off-road performance is greatly improved. Where the MT's would lose traction on mountain trails, the AT2's keep their grip and keep me moving.
