I thought they just changed the tire size...

I agree with Mychailo. You should use a 215/45-17 tire. To answer your previous question, even though the wheel is narrower, the tire would still be the same size. Thus leaving you with very small clearance. With a 215 tire you would be 8mm closer to the edge of the wheel well. A 225 tire would be 13mm closer.

Tire width/2 - offset. Take the difference of the two calculations to find change in distance.

215 also fits better on a 7 inch wheel.
