Also, if you take your car in and drop $40 or however much you’ll be charged, they’ll just drain the air and replace it with nitrogen. This will hardly be a pure concentrate because there’s still moisture inside the tire from the expelled air.

bingo. nascar and formula one is completely different, when tires heat up they def increase in pressure, they just want a more predictable outcome. the nitrogen will still increase in pressure, just not as much. hot brakes can cause aircraft tires to explode so heat is still a factor.
