Need help deciding on rim & tire package

[Skooter]

Hey guys, I'm going through the rims I'm considering and need a little help on the size and tire package to go with. I basically have it down to 4 choices for the setup I'm going with, what's your opinion on them?

I still need to decide what kind of tires to go with. My Celica is a DD so I'm wanting to maintain some form of comfort with the ride, mainly why I'm deciding on a 17"X7 setup. Is it possible to have 18" rims that would still be fairly comfortable? Or am I pretty much **** out of luck when I go up to 18" wheels? I would like the look of the 18's but from what I know a lot of comfort is sacrificed once we go 18"+, please correct me if I'm wrong. I've thought about 18" with a tire sidewall of 40 but I'm unsure of whether I'd be in danger of rubbing or not.

These will be sitting on Tein S-Techs btw. I've been searching through the wheel and tire threads and hoping you guys could give me some insight on what size I could get while keeping it somewhat of a comfortable ride. Sorry for the noob questions, thanks in advance fellas.
