[QUOTE="Todd Cloutier, post: 637136, member: 53897"] It's basic chemistry. Nitrogen, like air, Oxygen, Helium, etc. obeys the ideal gas law at the temperatures and pressures experienced by your tires. The equation of state for an ideal gas is P v = n R T P == pressure v == volume n == number of molecules of gas R == universal gas constant T == temperature which shows that the pressure of the gas in your tires is proportional to the temperatures. The pressure of your tires will change with temperature regardless of the gas the tires are filled with. Bottled Nitrogen has the advantage of being free of moisture, and that is likely why it is preferred by racing teams. It's also cheap, considering the atmosphere is about 78% Nitrogen. [/QUOTE]
