Nitrogen in tires
I have been told by our local tire dealer that since nitrogen is an inert gas you not will have the fluctuation in psi when tires warm up. How true is this statement? Thanks for your input. Skip

Bottom line-- you met a tire dealer who failed high school chemistry!
The Ideal Gas Law tops all advertising claims.
However, there are actually THREE types of gasses that are used in tires:
1. Nitrogen.
2. DRY air (like with a good compressor and quality air dryer)
3."Regular" air with moisture (like in those coin op air compressors)
1 and 2 behave very similarly. Since water is NOT an ideal gas, "regular" air does have more PSI change with temperature change.
