It will rub on-road when the suspension flexes like entering a parking lot ramp at an angle. Will also rub in the rear with passengers in the back seat. Will rub like crazy in the rear when offroad.
If you want easy tire clearance, consider a 1" body lift, TJ fender flares (requires minor sheetmetal trimming), and long add-a-leaf kits. I make my own 1.5" AAL kit using a used pair of front YJ springs, cut the spring eyes and use the top 2 leaves of each pack inserted in your stock spring packs.
Avoid shackle lifts.
