Haha, I understand what your saying.
On my car, when I had the stock wheels, they were no where close to flush. They stuck INSIDE the wheel wells by roughly .5"-1". You would think since my wheels are inside the wheel wells the rocks wouldn't hit the side of my car.
Wrong. On the lower part of my doors rocks stripped off a decent amount of paint. That's the reason I bought mine in the first place, so it doesn't get any worse. It's not even just dirt roads too. The salt in the winter acts the same way. Now that I have wider wheels it would be way worse, thankfully I have the mud flaps.
Look at the bottom sides of your car. It curves in towards the center of the car. This is just enough to make your front and rear wheels "poke" a little, shooting rocks at the lower parts of your door, side skirts, and whatever else.
Edit: that probably didn't make sense -_-
