chart for load capacity as function of pressure

My theory: Up to a point, the vehicle will drift/pull to the side with higher tire pressures, because the right-hand tires, at lower pressures, will roll at higher rpm. This might be the case with the right tires deflated to 34, 33psi, until resistance overcomes the higher RPMs, and ultimately, with the right hand tires deflated to 30psi or less, the car starts pulling to the right.

Your thoughts?

There are 2 competing things here: Larger diameter, more rolling resistance.

I'm of the opinion that RR is the more dominant because tire diameter doesn't change much with increases in the inflation pressure - at least for radial belted tires.

Before I had my car properly aligned, I was intentionally running the right tires 1psi lower than the lefts, to combat a slight left drift on highways. It did nothing. Nor did lowering the rights to 2psi below the lefts pressures. In fact, it made the left pull WORSE, likely because the right tires were rolling slightly faster.

I equalized all the pressures to be the same, left to right, and the left pull went back to being a slight drift. Alignment has since reduce the left drift to only occasionally noticeable.

Hence my theory.
