I had the E rated Duratracs, and they wore unevenly and got pretty loud. Definitely worse than the K02s I have had on other trucks, and they weren't really better than the K02s off-road. I know a lot of people like them, but my experience wasn't that good. I don't think they would be significantly different in D rated. I'm currently running a set of Ridge Grapplers that are down to their last 30% tread, and I'm debating between another set of these, KO2s, or the Toyo AT3, but not another set of Duratracs. Of the tires I've run, the Ridge Grapplers wear the most evenly, and aren't as loud as a worn set of K02s, but not as quiet as a new set of Ko2s. YMMV
