LOL, after all that I just re-read your original question. The tire site is just assuming you're clueless and would know if you've got sport/not rather than knowing the size of your wheels or the tire size you're looking for.

So if that's what you need this info for, sport/not does not matter at all, since it is so easy and common to put 19" wheels on a non-sport version. All that matters is what size wheels/tires you have/want.
