I have a 95 YJ with a freshly installed 2.5" running 31X10.5 on american racing wheels which are 15X8. I was wondering what size tire i can go up to, before they get too wide, and start hitting my leaf springs in turns. I believe the backspacing on the rim is 4" - I would like to go up to a 32X11.5 tire, maybe even a 33X10.5 or 33X12.5...would any of those fit? Thanks for you help.
