Some stuff here that is wrong. The impact of nitrogen vs. air is minimal because air is 78% nitrogen. It is a profit making upsell to the uninformed. If you have a race car or a plane then you might be able to make a reasonable case for nitrogen. For daily drivers, nope. Regarding rotation, unless the tires are directional tires or the manufacturer specifically doesn't recommend cross-over rotation patterns, a cross-over rotation pattern is fine. I have specifically asked Michelin about this and I have been doing it for decades when I haven't bought directional tires.

You cannot get all the air out and refill it with nitrogen. It does work-IF.
Rotating your tires.
OPINION-mine. I have my tires rotated front to back and then back to front keeping the tire on the same side of the car. The typical pattern where you cross from side to side,
you case the cross over tire to revolve in the opposite direction from what it was doing.
It can cause failure. It used to be more common than today but I've had tires fail due to this.
