I'm running BFG 235/85R16 Mud Terrain T/As on mine. I have about 3/4" clearance between the duals. The worst part about the Mud Terrains is they pick up and sling some pretty good size rocks. Other than that it has only been stuck once and that was when my 14 son was trying to get down to his deer stand after a 2" rain! Sunk it to the frame.
