Rated 5 out of 5 by from Good tire. Have these on my very heavy work rig. After about 30K with no problems they started cupping and i found one of my front socks had blown out. So i had to put them on back and go without rotations after that. But still got 44K out of them and they were pushed hard. Traction was great. I'd spin them up some loose rocky hills and would make it. Never had any sidewall give which is a concern for me when i load up the vehicle. A great product.

Rated 5 out of 5 by from 3rd Time is a Charm Bought Discoverer A/T3 for my 2003 Ford Ranger XLT 4x4. I replaced BF Goodrich, previous to those was Firestone. I am the original owner 102000 miles I am happy to report these Cooper tires are superior in all categories. They took minimal weight to balance, ride is superior, handling is excellent road noise is nonexistent. Traction in snow superior, no negatives at all. Best of all Made in the USA!

Rated 3 out of 5 by from All season? Maybe in the south These were on the Tundra when I bought it. Edges wore poorly so I had alignment. First winter on them. Half tread remaining and there is very little grip in snow.

Rated 5 out of 5 by from Excellent tire, great results The A/T3 is one of the best tires I've owned. I ran two sets of them on my 2500HD Silverado diesel and was extremely pleased with the quietness, traction, and treadwear (roughly 60,000 miles on a set, including a reasonable amount of gravel road usage). I wanted to buy a third set later for my Suburban, but I had to go with an ATP instead as the required size wasn't available in the A/T3.

Rated 5 out of 5 by from Zero Complaints. No uneven tread wear, no road noise and Zero Complains. I had these put on a new GMC Z71 off the lot and I currently have just over 59k miles on them. And I know I didn't rotate them as often as I should have.

Rated 5 out of 5 by from Awesome Tire ! Great Price ! I spent a lot of hours on the internet reading reviews and tests on many tires. I live in the mountains and go to work usually before the plows hit our streets. Actually, I sometimes take one of the snow plow drivers to work on my way to my bus driving job. My new A/T3s are fantastic. Driving on hunting trails I didn't have to use 4WD until the snow and mud got deep. I will keep you updated on tread life since I only have 3k miles on them. So far best tire I,ve had on my 2000 Wrangler.

Rated 5 out of 5 by from Best tire I've purchased in a while. I came from sets of Goodrich, Goodyear and decided to try Cooper and I'm glad I did. Cooper is by far the best out of all the tires I've had. Very quiet on road, solid traction off road. I've yet to have them in the snow but I doubt I'll be disappointed. I would definitely recommend these tires.

Rated 5 out of 5 by from On my second set. Ran a set on my 2013 GMC Sierra. Great on Minnesota deep snowy/icy roads. Traded the truck with about 40k miles on tires and they still had ample tread. Bought a new 2016 Sierra Denali last year and changed the factory slicks to these tires again. Love them.
