Hello edmo,
Yes I do have 18's.. Pros and cons, well the bigger size rims/wheels means the more expensive the tires will be. The stock tire size was 255/70r18(32's), and mine are 275/70r18(33's) so when driving on-road, I would probably lose 1-2 mph give or take..very minimal. Remember, the bigger you go the more power you will lose and eventually you will need to re-gear. If you are thinking about mostly off-roading, I would suggest 16-17's with more room for the tires(also cheaper in the long run). This is also my DD(95% highway/5% offroad) so I went with 33s as oppose to 35's. You can look at some of my pictures in my Jeep profile.
