Looking for a little more aggressive tire for my 2004 Chevy 3500 dually and want to stay away from spacers. Has anyone tried out the new BF Goodrich KM3 Mud Terrain in the 7.50r-16 size? An "Old School" size that BFG is reproducing in an "E Rated" tire. Skinny and 31.8" tall. Having a real hard time finding anyone that has used these. Single wheel rated at 2755 Lbs. Can't find the dual rating. Even the reps at BFG can't seem to find it easily. Anyone out there tried these?
