I've had a set on my 2004 Chevy 2500 for a few months now and really like them. Quiet for as aggressive as the tread pattern is and seem to be wearing just fine. BFG made a special compound for these tires that's harder and should wear much better than their KO2 line. Admittedly, BFG really had a problem with the compound on the KO2 for guys running them on heavy trucks. They're a great tire but weren't suited for heavier trucks, hence this new completely targeted design specifically for heavy trucks. They're designed with commercial applications in mind. I'll say this, I did have a little vibration in the rear and couldn't figure it out after a re-balance. It wasn't the balance, it ended up just being a small pressure drop that took the vibration away. Understand, this is a load range E tire and in an unloaded pickup, you don't have a lot of weight on that rear end. So, pretty freaking stiff at recommended pressure. SO, play with the pressure some until you find your own sweet spot. That's my honest .02 cents worth answer. Overall, I love them though.
