I fill my tires with 78% nitrogen (a/k/a "air"). It hasn't shown any pressure differential issues yet. If you will do your research, you'll find that many tire dealers sell "nitrogen" which is also 78% nitrogen. Some of them DO run it through a dehumidifier first, though.

If you have the sport package on your Z the 19" tires are filled with nitrogen from the factory!They will have either a blue or green cap on the valve stem so you will be aware.

Here in humid Houston, correcting tire pressure is a seasonal effort. We have three seasons -- hot summer (5 months straight), pleasant summer (5 months split at the bookends of hot summer) and brief, sometimes bitterly cold autumn (late December to mid February.

All are high humidity, which wreaks havoc on tire pressure. Nitrogen is a must here.
