Notable Features
Cooper Discoverer AT3 4S (AT34S) (presented in 2018) is an all-terrain tire for light trucks and SUVs, designed for year-round use in countries with a very soft winter climate. These tires can be used both in the city (60%) and in off-road conditions (40%).
The Cooper Discoverer AT3 4S performance does not depend on the weather conditions. The tire behaves equally confidently both in hot and cold weather, tightly contacting unstable and hard surfaces, which was achieved through the introduction of the manufacturerэs proprietary technology called Cooper Adaptive-Traction.
The tire tread is made of innovative silica-based rubber compound. It strengthens the Discoverer AT3 4S wet grip, increases the tire’s resistance to tear and puncture, and reduces rolling resistance.
The aggressive Cooper Sure-Grip five-rib design provides a possibility of off-road driving, combined with superb traction on wet and dry pavement. The zigzagging sipes on the tread blocks contribute to the vehicle’s stability, while the deep circumferential grooves reduce the risk of hydroplaning. The unique graded shape of the circumferential water evacuation grooves also helps prevent rocks from getting stuck in the tread.
To tackle the harshest of weather conditions, the Cooper Discoverer AT3 4S utilizes additional “saw-tooth” elements. These are meant to retain snow in the tread to ensure short stopping distances on snow-covered roads – because nothing sticks to snow better than snow itself!

Cooper Discoverer AT3 4S Latest Reviews
What is good?
Not bad for an A/T tire. Very quiet on pavement, quite smooth on most surfaces. I've put about 3k miles on them and about 3/4 of that driving has been done on gravel roads. Never had a fear of loosing traction unless I was really pushing it. Light mud never posed much on an issue. Done some water crossings no problems. Excellent hydroplane resistance.
What is bad?
Within the first 1500 miles I had to drive plug in the rear passenger tire in between the sipes on the tread block. Small rock got wedged in. So durability could be improved.
What is good?
Great in deep snow,wet,dry surfaces and light off road. They perform really well on my Honda pilot.
What is bad?
Only time will tell how they wear out.
What is good?
I have had these tires for a year. I'm quite satisfied. My car became quieter and smooth and handling was ok too. The tire offers mostly good all-weather performance and long wear. It handled well in the wet and hydroplaning resistance was excellent!
What is bad?
I've been disappointed with the wet braking.

Comments
Well in 6 months and 2k miles I can say they are overall great all terrain tires for city and light off road in my case. I can't comment on wear and durability yet, Only time will tell. What I can tell you is that I drove my Honda Pilot through 8 inches of snow including curved inclined hills like nothing I'm really impressed.
What is good?
I have had these tires for a year. I'm quite satisfied. My car became quieter and smooth and handling was ok too. The tire offers mostly good all-weather performance and long wear. It handled well in the wet and hydroplaning resistance was excellent!
What is bad?
I've been disappointed with the wet braking.
