Waste of money if one pays for that N2 “fill”. A tire “filled” one time with N2 STILL has air filling 1/3 of its volume. To REALLY fill a tire with N2, it must be inflated and deflated several times — at least FOUR times to reduce the air percentage to ~1%.
N.B: The physical characteristics of air and N2 are nearly identical. The real reason to have an N2 fill is to purge the tire of water, which does have a significant temperature/pressure effect because water vapor occupies many times the volume of water (about 1000 times at atmospheric pressure). Even then the single or multiple N2 “fill” is largely useless since tires are usually slathered with a soap solution as a lubricant to make mounting easier — and this always leaves a puddle of water in the tire anyway.
