Tire pressure hoax #1 – I mentioned low tire pressure to my car dealership and they recommended Nitrogen. http://www.pedrosgarage.com/Site_5/Nitrogen_or_Air.html

Tire pressure fallacy #2 When I mentioned low tire pressure to my friends they mentioned weather. I’m in Southern California so this means a drop from 90F to 40F. Sounds like a lot, but in Kelvin which is what matters, it is only 10%.  https://en.m.wikipedia.org/wiki/Ideal_gas_law

Tire pressure confusion #3 When filling tires I remember being warned about hot and cold tires. The same Kelvin scale as before says that at highway speed heating is only about 10% pressure increase.  http://m.caranddriver.com/columns/a-look-behind-the-tire-hysteria
