Look under 'FITMENTS', it says primarily leveled vehicles, then goes on about fully lifted. Anyway, the anwser to your question appears to be that the backspacing is shallower than most for that "deep dish" look. When you do this on a fat tire, you increase the odds that tire contact will happen on either the suspension, or the front bumper.
Ever seen rear wheel drive wheels on a front wheel drive car? They can be the same width, but the radically different offset makes them stick out REALLY far.
