    • 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). ... show more

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. ... show more

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.

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! ... show more

These Cooper tires are great, But they ship with FedEx, so there is no guarantee that you will receive your ordered tires. Once again, my order was messed up, and I had to go to the terminal to pick up my orders. Seller, I know Fed Ex is cheap, but please give us other options for delivery. As for the tires, they are great. They are quiet, the runout is very good, and they are easy to balance with minimum weights. The largest counterweight I had to use was a 2.5 OZ weight to balance them. The Good Years I took off had over 4 OZ on 2 of the 4 tires for comparison. Be warned. If you don't know, switching to an all-terrain tire will cause you to lose some MPG. Like any All-Terrain tire, you will lose between 2 and 4 MPG on average with all-terrain tires. But this being said, the tire quality is great, and it runs very quietly on my 2014 F150. They handle a lot better than the Passenger tires that the manufacturer installs. I would recommend them to anyone. ... show more

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. ... show more
