Welcome to this forum, and all things Jeep. I am pretty sure that you have 15"X8" rims. Which means that your rims are 15 inches tall, and 8 inches wide. The rims and tires that you have shown will work just fine. If you want them to stick out a little on the sides, don't have more than a 4" back spacing on the rims. This will also keep you from hitting the sway bar at full turn. The back spacing is the distance of the edge of the rim, to the back side of the wheel, where the bolt pattern is, on the mounted side. With the 9.5" wide tires, you should not have any problem with tire rub.
Never be bashful about asking questions, that is what this site is for, to share each others knowledge. Hope you stick around, and enjoy this forum.
