Well guys what is the best tire to run for a mud-terrain tire. I'm either going to go with B F Goodrich or Dunlop. Which are cheaper? Which are longer lasting? Which do better in the Mud? I'm going to put these on another set of wheels so I can just switch them when i'm going ot go out and this will save the life of the tire considerably. One more question, how do these tires hold up on the front of the truck due to the heavy weigth of the Cummins? Thanks
