Math. A 23mm tire will "open up" to 26mm on a wide rim. Larger diameter tire plus larger rim chamber = significantly more volume than you would think. If we treat the tire like a perfect cylinder and forget the added volume of the rim chamber (which adds to the percentage), the tire alone sees a 28% increase in volume.
23mm tire in a perfect cylinder: (2097mm ((pi)((11.5)^2))) 871,252 ml
26mm now because of the wide rim: (2110mm ((pi)((13)^2))) = 1,120,261 ml

Doh, indeed. You're not understanding the law, nor the application in this thread...again.

And on a wide rim with more V O L U M E that a narrow rim, it is unequivocal, indisputable, and absolute proof. But again, you seem to be missing that point completely....still.

Oh, so now you agree that a tire with a bigger volume due to having a wider rim needs less pressure. Great. Moving on.
