I have a 3 inch lift all around on my 1992 Jeep Cherokee and I was wondering if I could stuff this wide of tires without rubbing on my fender flares while turning? I currently have 31X10.5 and there is only minor issues with rubbing on the lower control arm when making really really sharp turns. Oh also I was wondering if the 31X11.5 inch tires will fit on 15X8 rims i would then put them on those rims, they have 4.75" backspacing would that rub? Thanks.
