With aftermarket wheels you can go with 31's if you don't lift it. How mine was, and it had no rubbing.
^^^^^^^^^^^ What he said.
Depends on what you want to do. I've seen some people that only drive in town and have no plan on taking it offroad (*then why buy a Jeep???*) and they squeeze up to 33x12.50's under their ride. Tis up to you.
You mentioned you have 15" alloy's...any idea how deep they are? That will help determine what width of tire you can put under there as well. If you have 30x9.5's right now I would guess you have a 7" deep rim. If so I wouldn't push anything wider than a 10.5" wide tire under there.
So...best bet: look for a 31x10.5r15 or 265/75r15
