upgrading wheels and increasing wheel gap?

it is my understanding that when we upgrade to 19s or so, the wheel gap actually increases, and therefore makes our car look like a 4 X 4. Is this not the case?

My friend and I are having a debate. He says when you upsize, it will fill the wheel well up, and you really don't have to lower. I ofcourse disagree, and just with pics of BMWs on 19s alone, they do look raised.

Can ne1 give a technical and good explanation of exactly WHY it gives the car a raised look? I can't quite seem to put my explanation into words.

The only thing you need to look at is the overall diameter of the tire. If it's smaller than stock, you will have more wheel gap, and vice versa if it's larger. The reason getting 19's without a drop looks like a 4x4 is that you have less sidewall on the tire, and it gives the illusion that the gap increased. Stock tires have plenty of sidewall (which is black and mixes in with the gap), and thus it looks okay.
