In case of Grabber ATX, their staggered shoulders also help in scooping the mud out but they are not as aggressive as the KO2. These shoulder blocks and sidewalls cut through the surface of the mud and the serrated shoulders scoop up the mud out of the tire, maintaining friction and traction. They further join in to the sidewalls of this tire which are also stronger with bulkier lugs as well. Not only they offer wider grooves allowing more mud to evacuate, but they also have edged shoulder blocks with deep incisions in them. Having said that, the BFG KO2 showed remarkable performance in comparison here. And you can’t expect the same performance out of these tires as you do with Mud terrains. Side Note: A better pick for On-Road would be Cooper AT3.
