At what point did I claim I am trying to achieve a better solution to BMW's engineering team on the X5M? Where did that even come from? Not to mention you're attempting to compare a wheel/tire size decision from a completely different chassis.

With only 6 posts to your username, you likely don’t realize that Andrewwynn is one of the most knowledgeable participants on this board, having done some excellent research, tear-aparts, videos and write-ups with photos. I have relied on and enjoyed his efforts, and would take his advice as I’m sure it was intended (helpful from a position of knowledge and experience and not condescending).
I took his post to be on the consequences of your upsizing decision, which you did not acknowledge in your initial post, and which could be significant with respect to drivetrain and electronics issues. The X5M is relevant as a “boundary” vehicle with the extent to which BMW engineers would go; to go farther is of course possible but of questionable value and with some risk if BMW chose not to themselves. My sense is that he was just trying to help you realize this.
FWIW I have 20s on my X5 and wouldn’t go larger for both ride comfort and the reasons Andrewwynn mentioned.
