This tire bridges the gap between an open lug tire designed for mud and snow, and an all terrain tire with lots of lugs lumped close together. The result is a tire that can tackle anything. I have 2400 miles on mine and there has been nothing that they couldn't handle. Can't say that about Bighorns. Got stuck in the mud with them too many times. The BD's just plow right through it. They may not last quite as long as BIghorns, but will probably go within 500 miles of it. Mine are now at about 3/4" depth at 2400 miles. They start off at 1 1/8". I would like to try some other tires just to get more experience with what's out on the market now, but I probably won't be able to jump ship on these Black Diamonds. They're just too good. My next set of shoes will be these!Read All Reviews
