Cooper Discoverer AT3 Overall Assessment

This is a highly rated tire and performs well over several different categories. 

The tire delivers rugged off-road performance and you can be rest assured you or your vehicle won’t be let down when taking on mud, gravel, sand, grass or rock. This is due to A divided center rib, Aggressive shoulders, and chip resistant tread compound.

This is a particularly grippy tire and has excellent traction on dry and wet roads. The wet road performance is probably most impressive thanks to the sophisticated silica-based tread compound which provides the driver with confidence and stability. It is also Interesting to note that the lateral protection the grooves provide act as a self-cleaning mechanism to reduce stone retention on the surface.

We suggest that you read our Duck Mud Tire Commander Review or maybe even Tires Duck Commander to expand your knowledge regarding tires.

Although not as bad as many of its rivals, the Discoverer AT3 tends to struggle when posed with the challenge of heavy rock formations and deep, winter snow. Again, these are not massive detractors but should be mentioned.

Overall, the Cooper Discoverer AT3 is a superb, adaptable all terrain tire that ranks in among the top contenders in its class.

Cooper Discoverer AT3 Tire Customer Reviews

Jarryd says: “This is my first set of Cooper AT3s and I can say unequivocally, they are the best tires I have ever owned. They have given me more miles than any other 10 ply rated tire. I am getting ready to replace them with the same tire and couldn’t recommend them more.”

Jarryd posted 4 out of 5 stars (4 / 5) review

Gavin says: “I have had good traction in heat, cold and rain. Cornering with these tires is something I look forward to and they are grippy around winding roads. No problems and the tread is holding up well after 15,000 miles. Would buy again.”
