I've run BFG Muds, MTR's and Mud Rovers. I have also run all 3 on the trail. My experience with BFG's is they grip the rocks great and they last well on the road but have puny side walls. I
my MTR's - been running them the past 3 years and I plan on replacing them with MTR's if finances permit - they are a sticky tire and they're street friendly as well. The Dunlop Mud Rover caked up quickly in the mud, and cupped over time. Cheap, but I wouldn't recommend them over the MTR's or BFG Muds.
