I will have to agree with the comments about the BFG A/T's, they are good for everything but mud. Especially if you have sticky clay, it just packs on and makes for 4 huge "mud" tires, literaly.
I have run BFG A/T's on my jeep cherokee and toyota 4runner but they didnt see as much off road as my Series. I am running BFG Trac Edge's on the SIII, but they dont make those anymore . When they finally go, i will get something agressive but not too soft. I dont have to deal with snow here so its not a big deal.
What i want to do eventually is have a set of high milage street tires and a set of off road tires for it. Swap on a set of MT's for when i go out to play and keep the non agressive tires for everyday driving.
