I have had both the cooper STMaxx and now the AT3W by Falken. I had great luck with the Coopers on a heavy overloaded truck, got 50K out of them including 3 trips to Baja, and another through Guatemala and Belize. I don't care for the Falkens at all, but I have a different application so maybe they will work better for you than me. (I'm a lot heavier) The falken sidewall to me does not seem to be as strong as the Coopers, it's only two ply. You might consider the Yokohma X-At over the Falken, I believe it is a 3 ply sidewall.
