Nitrogen is just not a tangible value to me. I get concerned when many of my friends have the impression that once they fill their tires with nitrogen they never need to check the tire pressure. If I had a free nitrogen station within a couple miles I'd likely continue to use it. It is not uncommon for me to see a 30-40 degree temperature drop in one day as a cold front comes through. That equates to 3-4 pounds of tire pressure lost which changes the handling characteristics of a vehicle quite noticeably.

Again, my point was not to knock nitrogen but to point out that, for many, a better alternative would be to spend your money on a good air compressor and check and adjust your tire pressure regularly.

Nitrogen does work however, but i've only witnessed actual Indy, Indy Lights, and F1 pit crews use it in their paddocks. It is more stable to expansion with heat cycling but still needs to be monitored.

bottom line, there is no advantage to nitrogen fill for daily drivers.
