If we could get some more guide lines....
Aggressive- Cepek Crushers, nitto mud graps
Long lasting- nitto trail graps, firestone MT, BFG KM2
I would stay with those because they toyo MT and cooper STT are more of an aggressive all terrain. I have used pretty much all of the conventional mud tires, back when the BFG KM was around. The best tire for the buck I would have to say Pro- comp mud terrain. Mine lasted 50,000 miles on a 3/4 ton that pulled quite often. Worked pretty good in mud and sand wouldn't go in any swamp but it is as close to the original BFG as I could find.
