I run nitto trails on my Jk and love em so far on road but haven't had a chance to take them off road. Run Cooper Discoverer ST Maxx on my 3/4 ton work truck and they're great tires. Great in mud, sand, rain, and on road. I've got half the tread left with 25k miles on em. I constantly haul ass down rough caliche roads with 1k pounds in the bed and haven't had a problem with losing chunks. A few other guys I work with run Cooper discoverer STT's and they don't last very long. They always chunk but I'm sure it's mainly bc of hauling tools and taking turns on caliche roads at high speeds.
