This one sounds reasonable, plausible and probable. So I will experience a decrease in the number of times I would need to inflate the tires.

Score a +1 for your bullet point.

I had to get two new tires(non z car,jfi)! New tires on the rear, old tires (but good tread) moved to the front. Rear new tires, were nitrogen filled(free, no charge, I didn't even request it).
That was 2 months ago, I check the pressure on the 1st of each month faithfully!
The front tires, I have had to add a pound or two of air each time. The rear nitrogen tires have maintained the same pressure.
