You might want to rethink that idea. As mentioned before, drum tests only paint you half the picture. On a drum the rolling resistance will continue to reduce as pressure increases. In the real world though once the tire has a bike and rider there is a break point. When you reach high enough of a pressure the rolling resistance will begin increasing rapidly. As in it's better to be severely under pressured rather than even a little bit over pressured.

Thanks for the link. Interesting. But, they were clearly riding rock hard tires to get to the point where increasing pressure increases effective resistance. Riding an unladen bike (not touring weight), I do not think I ever get over 80 psi, I do 80 psi on the rear wheel of my road bike with 28mm tires, wider tires get less.
I did the super hard tires thing decades ago with tubular tires, but I can't remember when the last time was that I rode such tires. I am sure it is over two decades ago.
