Cooper makes a pretty sweet mud terrain tire. It is the Discoverer STT. I was looking at Toyo and the BFG's and wound up going for the Cooper based on the recommendation of a friend. So far so good. They are quiet on the road and roll really well for an aggressive tread pattern. The price was in the same neighborhood as the others, perhaps a bit cheaper. No issues with water or mud yet and they have handled all I have thrown at them so far.
