205/45-r16 is a good size profile. I am running this size on my integra, looks nice, grips good. It should do well on a smaller car like yours. If you are asking about why guys in honda tuning might go with a larger DIAMETER tire, it's because they have used different size tires, and have found a size that matches well with their driving style and with the gearing that they have in their car - as you know, a larger tire means higher gearing, higher top speed, and possibly less burning out at launch. Their selection is based on feel, which comes from experience, no single tire size is going to be good for every application. hope that's a good enough answer for you.
