The gas mileage will not be significantly affected with the addition of the ORAII package. You also will not lose HP. However, the GC will feel less sporty with the 18" rims (vs. the 20" rims). The 18" rims will be better off-roading than the 20" rims due to their larger sidewall. The look is purely personal preference, so don't be swayed by anything anyone says regarding the appearance of the wheels.
To ORA or not to ORA. That is the question

Hahahaha that's an amazing coincidence! I replied because I was having hard time making the same decision. In my opinion, the 20" wheels are definitely better for on road performance. The 18" wheels feel floatier and don't give back as much feedback, in addition to not handling as well.LMAO!!! I think it's hilarious that, of all the people who could possibly have replied to me, it was you. Thanks so much for the reply. I was literally JUST looking at your pictures as I'm ordering the same jeep and color you have. Have never done anything aftermarket and a little disappointed in the dealer and Mopar's offerings. But I'm dying to get this thing purchased and delivered. I'll have to admire your photography until I can shoot some of my own.
Incidentally, how much worse would the street performance be? I'm getting the Hemi because it makes my size 14 Lead Foot smile! So I drive fast and mostly on road. But in winter and camping I'm up in Northern Minnesota off the beaten path.
The 20" wheels should be fine for what you are doing. After all, it is a Jeep. If you decide to do some more heavy-duty off-roading, you can always buy some 18" wheels later, whether they are aftermarket or OEM. I also am not a fan of aftermarket stuff.
As for the pictures, thanks for your compliments. I will be home in a week and will be taking some more pictures that are better than the ones I have posted. Also, check out Copefree's threads. He has 2 threads that include a lot of photos of his Granite Overland with 20" wheels. He also gave an off-road review of the 20" wheels that I found helpful when I was making my decision on what to order.
