I am aware that the KO2 is Snowflake approved but I was referring to the original BFG KO tire that was mentioned above that does horrible in the snow to say the least and is not Snowflake approved. With that said I have not read enough reviews or heard any good things yet about the KO2 in the snow being that it is a pretty new tire. Seeing that the General Grabber does excellent in the snow and has proven itself already I am going that route. Also right now Tire Rack is selling the Grabber AT2 for $151 (for 33's) a tire vs 195 for the KO2's. If I lived somewhere that had a real winter (not San Diego) I would go with the Goodyear Duratracs.
