I'm amazed at how many suckers there are in the world. Paying to have nitrogen put in your tires LOL!
It reminds me of the guys who went around getting signatures for a petition to ban dihydrogen monoxide. They argued it was the principal component in acid rain and if inhaled in large quantities could cause death. They got tons of people to sign the petition to ban it. Dihydrogen monoxide is water. Too many freaking morons in the world.
To the original poster. Just put 36 psi in the tires cold during these transition periods to cover the temperature swings. A few extra psi won't hurt anything.
