I would go Stt's all the way if it was between BFG and STT''s. I choose the Mickey Thompson Baja Claw for something different. But I would have had the STT's if I hadn't. The old BFG M MT's were a good tyre as I had these originally, however the tread pattern on the KM2's is no where near as aggressive and thus I can't see them wbeing as good on the dirty stuff. Why pay more for the same thing or should I say a lesser quality tyre. Buy the STT'S and be done with it.
