Duro tires are one of the few brands that have a deserved reputation, and I don't mean in a good way. Some brands are cheap, but still a worthwhile tire. They may be few and far between, but they are out there. Duro are cheap, but not a quality brand. Since you specified road legal, I can't even offer a recommendation, but for offroad only, I will recommend a Wanda P350 (Bighorn knockoff) as we have some guys who are running those tires and they do a very nice job in the dirt and mud.
