Im looking at buying new tires and wheels. My 98 z71 is sittin on stock wheels and 245s. Im wanting a wider stance and am wondering if 305/70 bfg muds or dc mud countrys would fit black rock dune wheels 16x8s with 5 in of backspacing and 13mm offset without rubbing. My truck has tuff country add a leafs and torsion bars which gives it 2 inchs (supposedly). Not really lookin to trim and really just lookin for about 1.5-2 wider stance so would go with 285/75s if it would meet that requirement and fit. Any advice would be appreciated, thanks
