I hate to hear the Cooper tires won't last. I was planning to try them next, but you guys have scared me off. I have no idea what to try next. I currently have Firestone Destination AT on my truck. They are good on the road and have held up well. I have about 50,000 on them and can get another 5000 or so. But they are the worst tires I've ever had for mud, and I've gotten stuck several times with them in places that should have never been a problem for an AT tire. I don't wanna buy them again, but I've got no idea what to get. I had a set of Generals on a new truck once and they were terrible tires, but that's been years ago so maybe they have improved.
