in fact, a little stretch is preferred in some cases.
i think the G8X run 285/30/20 on a 10.5 wheel on PS4S star which gives a little stretch.

I agree with what you are saying. I generally run tires on the max recommended rim width to maximize sidewall support and tread width. For example, 10.5" with a 265/35/18, while many people run that same tire on a 9.5 or a 10. The example you gave with the G8x still falls within the manufacturer's recommended max rim width. But, again, 295 is not meant for a 11.5 wheel (according to the tire manufacturers spec).
