I just swapped out my used up BFG All Terrains's for BFG Mud Terrain KM2's. I have to be honest, I think I prefer the All Terrains.
I've done a fair amount of research and at the end of the day, I always come back to BFG. They pioneered and created the All Terrain tire with the Baja races. For the release of the BFG A/T KO2's they just raced the Baja 1000 on a single set of KO2's and then continued to drive on them between for show.
My comparison was the Nitto's and while I cannot attest to the quality of them from personal experience, I can say that here in Florida I see many Nitto's (both mud and all terrain) with micro cracks in the rubber. Neither of my 3 sets of BFG's did that.
[edit: 29 June 2016]
I recently did a trip out to Rainbow River in Dunnellon, FL and I wanted to mention something in regards to traction in the rain. Let me preface this with a little bit of info. My tire sizes are a little smaller than they should be (in width and height). I was desperate for a new set of tires as my BFG AT KO's were almost slicks and I had 7 patches in them (4 in just one tire) and a slow leak out of the sidewall of one of them. A buddy of mine who owns a Rubicon Jeep got new tires and wheels and while a little too small, his BFG MT K02's would fit straight on to my wheels and he gave me all 5 for $500.00.
I have to say that I'm not as impressed as I thought I would be with the grip in rainy weather. I'd have to say that the AT's had better grip in wet weather. While I'm not condemning these tires by any means, I'd like to say that I personally feel that unless you are OFTEN in contact with muddy terrain, the AT's are a far better solution for the occasional off-roader.
Some additional information & contributing factors to consider with my opinion on these tires:
- I drive a Toyota Tundra, so driving with no load in the truck bed makes it extremely light over the read axles.
- I had 4 people in the cab which ads to the weight NOT over the rear axle.
- My tires are less wide than my truck can accommodate, and in fact are less wide than I should have on there in my opinion.
