Rated 5 out of 5 by from An excellent truck tire 2006 Ford F150 4x4 Lariat supercab. 40,000 miles the A/T3's and still running strong. No road noise, very smooth ride, great handling, claws their way through deep snow and stable traction on ice. Complete control during rain event. I now have a 2013 Ford F150 4x4 Lariat Platinum supercrew and will be shoeing it with Cooper Discoverer A/T3. Best darned tire I ever had on a truck. I did't rate the off road section because I don't drive off road on purpose.

Rated 5 out of 5 by from These tires are outstanding... I've been a loyal Toyo user for the last 20 years or so., and have used every different tire they make on 4x4 3/4 and 1 ton crew cabs with diesel engines. My current pickup is a 2012 RAM 2500 crew cab 4x4 Laramie with the Cummins engine. I've had it for 3 years, and until about 5 months ago, it had Toyo AT2 tires on it. It never did drive great. I am very fussy about maintaining the alignment, rotating on schedule, and running proper air pressure, and these tires only made it 28,000 miles and they were junk... Toyo used to make a great tire, but those days are gone. Now they are just selling the name, at a premium price. So, I decided to start researching tires to replace the worn out Toyos, and decided to go with the Cooper AT3 tires. To say I was immediately impressed would be an understatement... This pickup has never driven this nicely before. It was like getting a totally different vehicle. Very smooth, very quiet and very responsive and they were priced very reasonable, and on top of that, Made in the U.S. Doesn't get any better than that. After getting these AT3's, the only tires I will buy from now on are Coopers. I recommended these tires to a friend for his 2004 Dodge 4x4 crew cab and he is very impressed with them too...

Rated 4 out of 5 by from Good all-around tire at a reasonable cost So far I have 13,500 miles on them mostly highway. only minus on a Jeep Grand Cherokee Altitude with 20" tires is road noise above 65-75 no problems in wet.

Rated 5 out of 5 by from Impressed I purchased a set of these to replace the Goodyear Wrangler All Terrain on my wife’s Jeep. So far there is a noticeable improvement in traction in snow and slush. On bare asphalt they are smoother and quieter. Quite pleased so far!!

Rated 1 out of 5 by from poor side walls the tread is decent on this tire but after a year of having them the side walls are all rippled

Rated 5 out of 5 by from Smooth and well balanced I installed a premium brand tire last week and they were the worst tire I’ve ever owned. The following day I informed my retailer they were coming off and to order some AT3 Coopers. Once installed, the max weight I saw was 2.5 oz on a set of 285/75/17 10 ply (2016 Cummins). When I hit the road, they were smooth right up to 70 mph. Coopers should have been my first choice and will be for the next set!
