My experience has been those are WAY too big of tire and no amount of wheel offset is going to work. There isn't room on the inside if you move them in. My 215/15 65's hit on both the frame behind the wheel on the inside to hitting the fender on the outside. I don't see how you could put a wider tire on the car, there just isn't room. Not without making more room some how of course.
I mistakenly said I had 205s on my my car, they are 215s.
I believe you simply have too big of tires. You need to take a look at that, the wheel offset and the alignment. There is no easy answer to what you have going on other than the tires are too big, that is an easy start.
