What is all the hoopla about putting Nitrogen instead of air in tires?? anyone done it??
It's true, but not for the reason you infer; it's because the nitrogen is dry. Water vapor expands faster than nitrogen or air. If you had completely dry air and completely dry nitrogen, any difference in the rates of expansion would not be measureable.mercutio said:I believe nitrogen is also common in many racing series because it doesn't expand as quickly as atmosphere as the temperature rises (so tire pressure undergoes smaller changes throughout a run), but I could be wrong on that.
