i have a 98 TJ with 31x10.5r15 when I turn to both sides like for a U turn i feel some rubbing on both sides. im thinking about upgrade my tires to a 33x12.5r15 but im afraid there will be more rubbing so imm thinkin about add an 2" skyjaker and some wheel spacers to get rid of the rubbing. my question is how wide should the spacer be? im thinking on a 2" or what size do u recomend??  

I would invest in some new wheels with the proper backspacing before I went with spacers... but that's just me...
