I could see going with 225/45/17 on a 17x7 wheel, but any wider tire than that would result in diminishing returns.

With high performance tires and stiff enough sidewalls, you can get away with more pinching before diminishing returns (or physics preventing you from mounting the tire) come into effect.
DS national champion one year mounted 275 Hoosiers on a 6" wheel. The Hoosier has a ridiculously stiff sidewall, unmounted I can sit on the tire and take my feet off the ground without it collapsing.
Most CS folks run between a 225 and a 245. In general for autocross, the more rubber you can get in contact with the ground the better.
