Your in the mud now, you got to run with the BFG-s first

Then switch to a decent 275/60 drag radial.

Since you have a auto and BFG drag radial would probably work well and act like a street tire, yes there are better hooking drag radials but I dont think youd need one thats more slick like then street like, if that makes any sense.

But yea, it would be nice to see ya try your current BFG tires just to see how well ya can do.
