What causes the tire pressures to swing so much with temp variation is the moisture inside the tire. The reason nitrogen ends up being more stable is the moisture is removed as it is run through the machine or before it gets bottled. It is more dry than naturally compressed air, unless the compressed air is run through a good filter drier. There is moisture in the air contained inside the tire as it is mounted and lots of bead lube are water based. Usually there is a fill & purge procedure recomended to reduce that moisture when using N2.
