Exceeds expectations so far.
I've only put a couple hundred miles on them so far, but I put them through mud, gravel, wet grass, and a stream crossing and they handled admirably. They're easily the quietest AT tire I've had, virtually silent even at 80 mph. I'm really impressed by the manners on pavement, very grippy through takeoffs and in the curves. They felt a touch floaty on gravel, but nothing serious. Not as good as a dedicated mud tire in the muck, but I would class it as very good to excellent for an All Terrain tire. On wet grass it did extremely well, not aggressive enough to mess up the clients yard, but grippy enough to go slow without spinning out, same with the slick rock in the creek. I'm interested to see how these puppies do in the snow and ice this winter, but based on reviews and my experience so far I expect it will be good to excellent. Looks were secondary to my decision, but I have to admit they're a tough looking tire, at first glance you could easily think they were a dedicated off road tire and being an old fart with a white truck I like the way the raised white letters look too although I know that's not the thing anymore (don't worry you can put the all black side out if you prefer).

Great tires
I’ve had these tires on my 2500 service truck for a few years, they ride smooth, they’re not loud, and they haven’t worn down much at all. As for balancing, I have double beadlock wheels with rubber inserts so I use balancing beads (also purchased on Amazon) and there’s a negligible shimmy every so often. Also, the shipper, Autoplicity, has fantastic customer service.

Worth the money.
Second set of these tires I’ve had on 2 different vehicles. Low road noise as long as you have a good alignment and rotate on schedule. They last longer than most A/T truck tires. Good traction on all surfaces and they look good. Just wish they put white lettering on the 20” tires.

Overall excellent tire IMO NOT a loud tire either , minimal road noise ,depends on road surface , like new yet ,with a couple of thousand miles , long term should be good , from what I see as of now ... Seller was quick too ship... Excellent price Will buy again

Most well-rounded tire I can find!
I have less than 1k miles on these tires at this point, wanting to get a quick review out there to help any buyers interested in this newer release! I had difficulty finding reviews on these. These tires are extremely similar to the standard AT/3, which is an already excellent tire. The additional features on the sidewall both look good and should perform better for off-road durability, which was never really an issue. On the road, these tires are almost silent when new, and ride very smoothly and seemingly efficiently. I would recommend them as one of the better tires for this price point! UPDATE*** I just completed a 5,000 mile tire rotation with my tires. I added a photo after wheeling the Daniel Boone Backcountry Byway. To this point, the tires are wearing very smoothly, riding quietly, holding their balance, and very capable off-road. I have had one puncture from a screw that was easily fixed with a tire plug. I still highly recommend these tires! UPDATE*** 10,000 mile rotation is great. Haven’t been balanced since initial installation, and have been off-road on multiple occasions. Still silent on road, smooth, with VERY minimal signs of wear! Buy them!

Good tires
The words that were supposed to be white were covered in blue, other than that they were as described.

Awesome Tires
These replaced a set of Toyo Open Country3’s on my 2020 4Runner. They look equally aggressive and perform great on and off road and best of all - almost no road noise!! I literally could not handle the Toyo road noise anymore - they had 60k miles and still good tread but more than an hour on the highway and my ears were ringing.
