17x or 18x
What's the difference between running 17s or 18s? Any pros? Cons? Recommendations? Suggestions? Modifications?
I hear if you run 18s you have better handling/gas mileage. Dunno if that's true.
Btw, this is out of sheer trying to understand the difference between running the two.

It's really preference. An 18" wheel + 35 series tire is going to be negligibly taller than a 17" w/ a 40 series tire (for example a Dunlop Star Spec 255/35/18 and a 255/40/17 are both 25" tall). I personally like 17s better because they weight less (a little) and tires are less expensive (same example as above: $249 vs $172 respectfully). Due to our limited offset allotments, 17s also have a wider variety of wheels to choose from Due to the shorter sidewalls on 18"s (35 series), they do provide a stiffer sidewall that can improve handling.

You get more options to run wider rubber in an 18, wile also maintaining or changing the effective gear ratio you want. 17's are limited in this manner. 17's are lighter and less expensive. 18's are more versatile. Pick your poison.
