Look around on some boards see if you can snag a deal on the 32's that come on the JK Rubi. I know a lot of folks are pulling tires right off to go to 35's and the like....
Other than that, I like the BFG A/T's. They have always served me well. I have heard good things about the Firestones as well.
And...as you will see in one of the other forums...I am researching the Toyo Open Country's too...but can't reccomend one way or another on those. Trying to find out myself!
