Cooper has designed this tire to withstand the rigors of off-road driving while still maintaining a comfortable ride on paved roads.
Noise Levels and Comfort
As someone who spends a lot of time behind the wheel, comfort is paramount for me. One concern I had with all-terrain tires was road noise, but the Discoverer AT3 surprised me. The tire is engineered to minimize noise, and I noticed a significant reduction compared to other tires I’ve used in the past.

Finally, I want to touch on installation and maintenance. I had my tires professionally installed, and it was a straightforward process. After installation, I made sure to keep up with regular rotations and alignments, which has helped extend the life of the tires. The maintenance is minimal, but I do check the air pressure regularly to ensure optimal performance.
