Tyere with nitrogen

With the rising prices of petroleum based fuels - most remarkably gasoline, the motoring public is looking for ways to get better the fuel efficiency of their cars. While the reality that the tires play a major role in the fuel efficiency of a car is forever ignored, the US Energy Department stated that by having under inflated tires, we lose as much as two million gallons of gasoline daily. The most commonly used gas to inflate a car’s tire is oxygen. The use of ordinary gas can lead to earlier diffusion which will result to an under inflated tire. The answer to this quandary is the use of nitrogen. Since nitrogen diffuses slower than oxygen and is more plentiful, the gas is a valid solution to the problem.
