So, I'm actually an engineer for a tire company, and this is not how it works. When an OEM seeks out a tire, they reach out to the tire operations that they feel can provide what they want. Engineers from the OEM give specific characteristics of the vehicle to the tire engineers and the team goes through several "iterations" of test tires until the OEM is happy with how the tire performs on the car. That tire is specifically tailored to the vehicle it goes on. The price is only one small step in tire selection.
That being said, to the OP, 225 45 is a good match on this car for a more grip oriented tire from the performance summer category. I upgraded to an high performance summer tire in the stock 215 size and I'm not lacking any grip on the street and still have tons of fun at autocross.
