Started with 18" and have NEVER regretted it!
I'm able to get an 18x8.5 front with 255/35 (wheel only weighs 17.8lbs) and 18x9.5 rear with 265/35 (wheel only weighs 18.5lbs). Saves about 10lbs per corner of rotational mass and you can feel the difference!
Get a set of wheels with the spokes going all the way to the lip. Difficult to tell they are 18".
Added sidewall helps quite a bit for rough roads.
