I am a nut about tire pressure and check it offen. If an installer has a good nitrogen machine it first cycles out all the air, and then it installs the nitrogen to the set pressure. Nitrogen is 99% dry and therefore is not technically affected by ambient air temps. Tires also carry less heat in hot temps with nitrogen.
got any info that backs up the tire hold less heat with nitrogen? Nitrogen can be heated just like all other gases.
