In AC, you can do a setup and name it "AI_Default" and it'll force the AI to use that setup. It's a fantastic tool for offline racing.

Is there any way to force the AI in PC2 to use a particular setup? Or even just to use a particular tire?

Example: The "Track" tire used by the Vintage Protoypes is way too grippy, the "All-Terrain" tire is just about perfect, but there is no way to force the AI to use it (it always uses the Default tire, which is "Track").
