What's the largest set of tires I could put on a '91 Bronco w/ stock axles? I have 35" BFG muds on it right now. But down the road after I finish fixing the suspension the previous owner dicked me over on(6" superlift w/ rear blocks, stock pitman arm, stock radius arms bleck!) i'd like to throw a 3" body lift on and maybe run 37's. But i've heard the TTB can't handle 37's, but the 8.8 can.
