This should tell you. I don't think it's any coincidence that the stock wheels are stretched to their limit, so you can't put wider tires on there, sort of self-limiting. Most manufacturers do this, rather than make wheels wider (and more expensive) than needed. The tolerance that I selected for the radius was based on what I wanted. I can input any tolerance that I want, but you can see whether or not a different width and profile will lift or lower the car and how much. The 2nd step would be to list the % change and speedometer effect.

I also made an excel program for the offset to compare against stock (in this case for my winter setup).
