I'm no expert, actually not even close, but I think that you are going to have serious problems running 14" wide tires. You will lose much of you turning radius due to rubbing, and I think that even going straight, the backspacing will be a problem. The Dana 30 in the ZJ is weak. Mine's bone stock, and needed all of the bearings in the axle replaced by 60K miles. Ithink thta your wheel bearings will not live long with such big tires.
