That is great information about 18's! I was not aware. Aesthetics are purely subjective and beauty is in the eye of the beholder.
I am not opposed to 18's. I just like the look of the 17 inch wheel on my Dart. My inspiration came from a car just like mine I saw on the freeway and when we finally stopped at the off-ramp, I asked the tire size and wheel size. I thought the amount of tire to wheel looked great. I think with 18's, I would be limited to low profile tires. My knowledge is limited as you can tell. I also would like a slight rake to my car without wrenching down on the torsion bars. Maybe a taller tire in the rear?
I'm thankful you're so helpful to me.
