Hey Kyle, you'ld be surprised at just how big of a tire will fir your truck without doing much of anything to the suspension. I've put 32x11.50x15s under stock 1/2 tons from '64-'72 without any rubbing problems. To get it up on the cheap, you might consider putting 3/4 ton springs in it, that should get you at least 2" lift. I would advise putting power steering in with any wide tire, they can be a bear to steer without it.
