<strong>Comparison</strong><br />BFG is a little late to the game with 40-plus-inch tire, but the wait was worth it. Here the new 42-inch KM2 (center) is compared to a 42-inch Irok from Interco (left) and a 39-inch Krawler (right). We measured the KM2 at just over 41 inches. For such a big tire we felt the tread depth was a little shallow. The Mud-Terrain is definitely quieter than the Irok or Krawler on the street, and performs as well in the mud. We feel the M-T is a better tread for the all-around truck that sees street duty as well as off road, where if you are building an extreme buggy, you'll most likely want one of the more extreme treads.
