I currently am running 275/70r18. Probably losing 1-2 mph give or take and they do still rub with 1.5" spacers(full turn in reverse) on the airdam. You could add washers or just pull the plastic airdam off. Other than that it's great and probably going with 285's on the next set.
I try replying back but your mailbox was full.. Here is what I wrote.
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.
