Go with an 17" x 8.5" max.
These calculations are base on the assumption that your current tire is the OEM Wrangler SR-A - 255/75 R17
I believe your rims are 17" x 8" -- I wouldn't go with the 9" wide rim unless you're getting into the 12.5" wide tires, it'll look goofy when installed. 8.5" in my humble opinion would be the max. 8" would work too. Just because you go 1" wider tire doesn't necessarily mean a 1" wider rim. 8.5" and you can still put a (33,35,37 x 12.5") on it down the road.
