you might think I'm crazy, but I want to go with 17" front and 18" +wider rear for that 'rod look. I always feel that with the hatch, it gives the illusion that the rear wheel has a smaller diameter when it doesn't, I want to correct that. I know, crazy idea.
You're 100% right the rear wheel does look smaller.
I was think of putting a higher aspect ratio tire on the rear, to help even it up visually, but I don't want to slow the car down, upset the handling, or increase ride height. I'm not sure it would, but I'm not sure it wouldn't either.
I did some calculations at first, if I run 225/45-17 up front and then 265/35-18 out back, the overall diameter difference is only 10mm. or 3% difference on the ODO.
I think going up 1 inch on the wheel would improve the look more than going with a taller tire since the sidewall will just blend in with the wheel well. I'll keep you guys posted if this works out or not.
18x9.5 would be an excellent choice. A 265/35/18 will fit under there w/o issues.
The 17/18 would look funning IMO. The rear fender lip is already cut lower than the front. An 17/18 would further add to the illusion of rear sag based on wheel lip to fender spacing. Or maybe I'm wrong and because it is that much more drastic, it'll look just fine.
