X2! I had the Firestone Wilderness AT's on my Ranger. They were great tires and also had good tread life. I only replaced them because Ford offered money, enough to partially put new wheels on too. I ended up upgrading to a larger tire and wheel. I have also owned the Firestone Destination M/T's, also a great tire. I don't believe Firestone was at fault. Under inflate any tire too far for too long with too much load and problems will arise.
