Rated 4 out of 5 by from This is a great all around tire I put a set of these on my f150 over two years ago and have had nothing but good luck with them. I dont know how many miles on them but i drive allot. Tbey are great on all road conditions, i have had them in rocks and mud on old logging roads i probably should not have been on and have never gotten stuck. I am thinking about a more agressive tire next but may end up with more of these, they have been great.

Rated 2 out of 5 by from Disappointing Capabilities I use my Sierra 1500 off pavement enough that the P metric radial sizes lack the durability I need. Pavement use was adequate but repair replacement cost of the P metric size was very disappointing. The nearby tire dealer recommended the Discoverer A/T3. The A/T3 has been a big disappointment. My only positive about them was that I never had a single flat with the set of four. Especially on pavement these tires are rough. They were rebalanced multiple times but they always rode on pavement like they were out of balance. The best smooth pavement did not improve their ride quality. After about 10,000 miles I replaced them with a different brand and they reside in my storage unit.

Rated 5 out of 5 by from All Around Great Tire Long Island New York. Seldom do any reviews include location, the tire, tire size and vehicle. After extensive reviewing and my previous experience with Cooper AT's and their improvements with A/T3's I knew I would go for the A/T3's. I had 35x12.50 R20 installed by Mavis on 2007 F150 SuperCab. They were installed the day after we got about twelve inches of snow. My first Impression was excellent. In the snow they had outstanding grip. The next day on cleared but salted roads I drove home about 105 miles on highway, an even better impression. No road noise to speak of, super smooth ride and no trouble balancing with 10 oz of ceramic beads in each tire. The next day I towed my camper just as easily and more comfortably than usual to Smith Point County Park. Got to the beach, aired down to 20 PSI. I was driving every day on the beach, loose sand, hard packed sand and everything in between, even some small boulders at low speed. I drove back to NJ 105 miles in the pouring rain deliberately at dry conditions speed. I could not spin these tires from a dead stop, nor hydroplane them at speed that other drivers were getting away from. I never even felt a sudden shift from hitting standing water. I could not believe what I was experiencing. My first set of Cooper Discoverer AT's were installed on my previous F150 CrewCab before I bought it with only a few thousand miles on them. I personally put 50k miles on them and they still had 5k in them. Thanks Cooper for making such an excellent tire that will far exceed my driving needs. Pure Bliss!!!

Rated 1 out of 5 by from Doesn't last long The tread doesn't last long at all especially considering the cost. . They're not like they used to be. Almost time to replace and not even 20,000 miles on them, very little highway driving. So much for going to to the STT pro's, time to switch brands

Rated 5 out of 5 by from Performs better than expected On and off road these tires perform great. On road 20K they are great haven't noticed any at all. Off road two separate trips on the 216 mile Lassen Applegate Trail no problems. Towing a 4K trailer and two 1000 lb Arcticats threw the Black Rock Desert wet grease No Problem. Saved my butt. Thanks Cooper ! Will get same replacement tires when needed. Long time from now.

Rated 4 out of 5 by from Good all around tire I put them on my 08 GMC Sierra. I was concerned about noise and a rough ride. Had neither. They are relatively quiet with a smooth ride. Plenty of traction. The only issue I had was, they seemed to throw more stuff from the road up the sides of the truck. I will buy these again.
