walmart.com

I had these installed on my 2015 3500 Ram Dually about 2 weeks ago and so far all I can say is WOW. I had H/T3's on before and thought they did a good job but I actually think these new ones are even quieter on the road than the HT3"s. They handle nicely. I have had a chance for adverse weather yet so stay tuned.

A/T3 LT

coopertire.com

I've had these tires for over two years now and have not had any problems with them yet. They are on a 2012 Toyota Tacoma 4x4 that I use daily and have to depend on to get me through any type of weather. These tires have worked extremely well in all types of road conditions to include off road.

Great all around tire.

I always buy Coopers for my work truck because they have the highest weight rating of any tire that i can find. Have been running 265 75R 16 LT3's, and have have always been pleased with them. Being a contractor, and having a truck that weighs 8460 lbs with no cargo in it, whenever I have a yard of sand or gravel loaded in the back, the poor tires on the rear are then each overloaded about 1000 lbs more than they are rated for. And i have carried a lot more than that too! Even so, have never had any tire failure with these tires. I Highly recommend them. I don't recommend overloading them though. But hey, what is one to do?

Very Positive

I'm on my 3rd set of Cooper AT3s for my 2012 Chevy Silverado 3500HD Duramax dually, now at 155,000 total miles. I work these tires pretty hard, sometimes towing a 12,000 lb 5th wheel and other times carrying a 4,800 lb Arctic Fox truck camper, most recently to Alaska from New Hampshire and back. I've never had a failure, they run quiet and wear very well. I do rotate every other oil change, check pressure frequently, and stay on top of alignment and suspension services. I like that these are US built too. I'll be buying my next tires from Cooper.

Great value and performance! Made in USA!

April

I ran cooper ST for years. Now that was the best tire cooper ever built imo. These AT3 were supposed to be the ST replacement. Cooper missed it bad. While the AT3 cant even hold a candle to the old ST in off road truck use,  they are a great lighter duty tire. The only real problem with the AT3 is in mud they pack up instantly and dont clean out. But otherwise,  wear like iron, good on snow and ice.  An origional set of AT3 bought in 2009 for a light suv, , after 30,000 miles, still have over 1/2 tread. A set bought in 2011 on a gmc 1500 4x4 ,after 50,000 miles, some towing n hauling, still look fine almost 1/2 tread left. In feb 2020 we installed a set of AT3s4 on wifes new ford escape. The factorty tires had horrible road noise and rode lije crap. Over 20,000 miles, they still look new.  The AT3 are very quiet, good ride &  wear great. Actually a great all around all season tire. Just not good in mud.  Cooper needs to bring back the Cooper ST. The ST were awesome on working pick up trucks and heavier suvs like tahoes & suburbans that seen alot of PA montain country roads and hard use.

Cooper is very generous with the tread width and that means a stable tires that grip well on the turns. I have driven 30,000 miles on these and still have 80% of the tread left. They are very quiet on the highway and have tremendous ride comfort. I do suggest that when you rotate them put the back wheels directly to the front and criss cross the fronts when they go on the back - this will help the large lugs wear with less potential of cupping. They are not meant for heavy snow. So if you livd in a big snowfall area get dedicated winter tires. I will buy these again. Why? Because they are the best road performing all terrain tire I have ever used.

Ridiculously comfortable, excellent cornering.

Put these on my 2004 Ram 1500 and they are great. I have 60,000 plus miles on them now and they have not let me down. I am a nurse and have to travel daily for work so weather cannot stop me. They work great for off road, snow, rain and daily driving. I would recommend them to anyone. Cooper makes great tires.

Excellent Tire

I use these on a Chev 2500HD that mostly hauls a truck camper. Roads traveled: About 60% highway, 35% paved 2º, 5% dirt/gravel. Reasonably quiet, fairly good in the snow, good in mud, excellent in the rain, rock solid dependable. I do not get 60K out of a set but, I suppose, that's to be expected with 2700 lb+ camper sitting in the back most of the time. This is my third set; God willing there'll be a fourth.

Excellent except wear could be better

I bought these as my main winter tires. I do a lot of highway miles for work and pleasure, but also a fair amount of wet weather driving, snow, and dirt roads for fun. I am liking the way these tires perform! They are smooth and quiet on the highway, but definitely do well on wet roads and snow too. I took them 4-wheeling a month ago, and tackled a pretty tough old mining road with a lot of sharp rocks. I even managed to get a deep and long gash on the side-wall. The tire didn't fail, and I drove it 500 miles home! Not sure how they will wear in the long run, since I've only had them for a few months, but so far very happy..:-)

Really liking them so far!

I have a set of these AT3 for a couple years now. Were advertised as a 60,000 mile tire.  Will be lucky to make it to 40,000. Kept up with rotating. Traction on snow and ice has gotten horrible with there still being 3/32 to the wear indicators. Have a set on my truck and wife's suburban. About the same mileage on both. Regret both purchases. Ran the old plain ST's for years on all my work trucks, and personal truck. They were got tires. The AT3 is not.

Miss the mark.
