This is a quick review of the Cooper Discoverer AT3 LT (ATs). I've had these for about one year and put on only 10,000 miles due to 2020 being crazy. Previously I had the Cooper Discoverer S/T Maxx hybrid tires in the same exact 275/70-R17 size and E-rating. These tires have been great for me thus far and suit my needs perfectly. I really like what Cooper is doing with their tire technology, but there are still many great offerings from BF-Goodrich, Toyo, General Grabber, etc. I love me some mud terrain tires, but I had to be honest about my needs and get an all-terrain.
