Rated 2 out of 5 by from Tires were shot before 40,000 Overall a good tire but was at 3/32 before 35,000 miles. I rotated them myself which apparently voids any sort of mileage warranty. Had to replace all four before 40,000.

Rated 4 out of 5 by from Nice tire with caveats Great tread and surprisingly quiet for an AT. Seems to handle well in different terrains and bad weather. With a higher/firmer UTQG rating than the OEM AT's that came with the truck, I was hoping for close to equal mileage but have lost about 2 mpg. Consider that if buying for your daily driver.

Rated 1 out of 5 by from So loud I can hardly ride in my 4Runner I have had these tires about 18 months . They have been maintained and rotated exactly as they should have been. The treadwear is great but they are so loud that I cannot hardly listen to the radio or talk on the phone because of the roar. I have to get new tires much sooner than anticipated because of this. Ratings said they were quiet, but they definitely aren't.

Rated 5 out of 5 by from on my second set I had a set of AT3 p225/75/16 on my Jeep Liberty. they have a 50k rating, but I got 70K miles out of my first set. so I got LT225/75/16 this time wanted a stiffer ride. they are awesome in any condition, on or off road.

Rated 5 out of 5 by from Longest lasting tire I've ever owned I put a set of 265/75/16 A/T3s on my Chevrolet K1500 at 161,000 miles thinking they would be the last set before the truck died. At 267,000 miles I replaced the A/T3s. I probably could have gotten another 5,000 miles out of them, but I was about to put 4,000 miles on them on a hunting trip out west. Yep, I got 106,000 miles out of one set, the tire dealer I buy from did a double take on the work orders mileages. It pays to rotate every 5,000 miles, check the tire pressure often, and don't abuse your equipment. I use the truck for commuting, towing my boat or camper and for off road hunting. Waiting to see which wears out first- the tires or the truck.

Rated 5 out of 5 by from Excellent Tire for all Seasons My BF Goodrich OEM tires on my 2008 Nissan Frontier SE 4X4 didn't last 40,000 miles, so after researching what was available in 2011 I settled on the Copper Discover A/T3 LT265/70R16E which came with high ratings from Consumers Union. I just purchased replacement tires with 115,000 miles on the truck. That is right over 75,000 miles on a 55,000 mile rated tire ... I couldn't be happier. Actually, I should have gotten another 5,000 miles out of them but I had a construction screw embed itself in the sidewall of one tire, which was not repairable. It was time anyway as I had gotten my money's worth from the 5-year-old tires in all kinds of weather and every conceivable road condition. I should add I tow an 8,500 lb travel trailer and have had no problems towing or stopping the rig

Rated 2 out of 5 by from It's not as good as I expected I live in Northern Minnesota and have mostly ran mud tires year round. I figured I would give these tires a shot. Put it this way I had way better traction on snow and ice with Interco Thornbirds than the Cooper AT3.

Rated 5 out of 5 by from Great Looks & Treadwear I have had these on my Toyota Tacoma for 4 years and 63,000 miles. They still have 4/32 tread but I am buying a new set because ski season has arrived and I am worried about driving in the mountain snow. Never had a flat or any other problems with these tires. Best tire I have ever owned.
