It should be obvious to all that there is a bursting pressure, and higher pressure is closer to it. That's all I meant, don't read any more into it.

It seems obvious to me that the sidewall pressure is the highest pressure that the manufacturer is comfortable specifying. I have no special tire knowledge so I have to rely on the manufacturer.

Well, for one, I am talking from my own experience. 8 years and over 200,000 km driven on 10PSI on multiple vehicles ( see previous posts).

When I first got introduced to this concept, my jaw dropped on the floor.

The thing is, 10 minutes after (being introduced to the idea), I had the opportunity to experience it right away and I was sold by the end of the day.
Good for you. You have more faith than I, even though you profess none on the other hand. As I stated before, your fuel efficiency gains are minimal after exceeding the sidewall maximum, and you are running with less margin of safety. Since you are not a tire designer or a scientist, why can you not just leave it at that?
