Shouldn't be a problem. I don't know the back spacing and offset of stock rims, but 31x10.5 tires are put on stock TJ Rubicons. Mine is a sport and that's what I drove it off the lot with. At most you may have to add a washer to each side of the steering...whatchamacallit... but should be good to go.
