Rated 5 out of 5 by Excellent tire on all counts. Ive had a set of AT3's on my GMC truck. I do alot of hauling and towing. At 40,000 miles, they have a well over 1/2 the tread left. I also have these on the wifes SUV. We live in the country with alot of mountains, steep inclines and winding dirt roads. They perform very well summer & winter. They also perform well for interstate driving wet or dry weather. I ran the Cooper ST for years and loved that tire. I would get 80,000 + miles out of them easy. I was VERY dissapointed Cooper discontinued the ST. But these AT3's seem to be the next best thing. The AT3 may not have quite the mud/snow traction the ST did, but it looks like they may last a little longer. September 22, 2016
Rated 5 out of 5 by Excellent wear 78K miles. I expect to get another 5K or so. They need to be rotated regular but man did they last. I run 45K miles per year in Houston. Wet or dry these do great. This is a 3500 4X4 truck with lots of towing! September 15, 2016
Rated 4 out of 5 by quiet at first; tough; long lasting We put these on our 2011 Jeep Grand Cherokee Limited 50K miles ago and they have offered good, not great traction in snow. They were very quiet at first, but after 15K miles started to get noisy. Now they are very noisy. We rotate them religiously every 5K miles. The tread wear has been even and will still go one more winter here on the west slope, Northern Sierra Nevada. I'm impressed enough with these to put the same tire in the LT295/75R16 size on our truck camper. The reason is the high load capacity (3970 pounds per tire) which you need with a 10K pound, 4WD, truck camper.I'll review how that goes. jefe September 13, 2016
Rated 4 out of 5 by So Far - So Good I've only had them on my truck about 2 months (maybe 2500 miles) . At first they were a little 'squirrelly', but as I wear them in, they are getting better. Replaced Hankook with the coopers - I think the Hankook was slightly better tire, but more $ and a little more road noise with those. I put the coopers on a 2005 F250 Diesel that I frequently tow 8000+ pounds with. Yes, it's an F250, but I have F350 springs in the rear, with an extra leaf, and F450 Springs in the front. The truck rides HARD until I have 500 - 700 pounds on it. I have not had the opportunity to use them in the snow. So far, dry and rain use only - and traction is good. I do not use them off road (occasional field or unpaved road). Non-aggressive driver, but do sprint from a stop sign or light if needed (mostly not). 122K miles and this is the 3rd set of tires for that vehicle. I've owned it since new. September 9, 2016
Rated 5 out of 5 by Perfect all-round tires We've put these on my '03 Suburban, '11 4runner, and '13 Tacoma, and they have lasted both summer and winter throughout. on the highway they aren't too loud, and off road they are phenomenal. We took both the Tacoma and the 4runner up Mosquito Pass, CO, right after a rain storm and they perform brilliantly. Highly recommend these tires. September 4, 2016
Rated 3 out of 5 by Great looking, decent overall but loud Got these on a Jeep Grand Cherokee, replaced the HTPs which I was happy with but wanted something more aggressive. After a year and about 30,000 they were shot. Feathered, uneven wear and cupped. Just not a good choice for highway and street driving. Replaced them the H/T. Even though I'm disappointed in these, it was more of a bad choice in style and I'm still a fan of Cooper Tires. August 31, 2016
Rated 5 out of 5 by Quiet tire, great wet traction, looks really good I put a set of AT3s on my 2014 Super Duty. They are as quiet as the Michelins they replaced. Their wet traction is very good. I drove through a heavy rain and did not notice any loss of traction or hydroplaning. They slice through water with confidence. Tire dealers like to steer you away from Cooper referring to tires like Toyo as premium tires. I was told Cooper is not a premium tire. Bottom line is the AT3 looks and drives like a first class tire. If they perform great with towing and with off road conditions, I am a dedicated customer. So far the AT3 has turned out to be a great tire for the 20 inch OEM wheels on my Super Duty. I am only rating them as average for off road and winter traction as I have no experience wit them in these conditions yet. August 24, 2016
Rated 5 out of 5 by Cooper A/T3 I have had GREAT luck with my A/T3 tires on my Colorado 4WD., I have over 50K on the tires and probably just under 1/2 tread left. Not bad for a 40K tire! Very happy with the handling (wet and dry), low noise, good traction on snow, etc. I will definitely replace my A/T3's with more A/T3's. August 24, 2016
