So I was walking through Costco and saw banners all over exclaiming the greatness of their new method of tire inflation, they mentioned it was better for handing, and tire life. Ok you rocket scientists, can you give any actual explanations?
Of course nitrogen expands with increasing temperature. Where did you get this idea?
Air is mostly nitrogen. The only benefit of filling your tires with pure nitrogen as opposed to air would be the lack of oxygen which does over time cause damage to most rubber products, however I think this is another case of companies trying to use science to bamboozle the masses. Because as you see above, people in general have poor knowledge of science and will believe anything they're told.
10) Pure Nitrogen Inflation of Tires Increases Tire Life 25%
Pure nitrogen increases tire life 25%
Nitrogen remains in the wheel longer resulting in better fuel efficiency
It is less likely than compressed air to corrode rims and deteriorate tires
Normal compressed air contains 80% nitrogen and 20% oxygen plus moisture
Membranes in nitrogen separators/compressors filter out oxygen and moisture, last 10-years
Nitrogen used in racing and aircraft tires because non-flammable
Nitrogen use in tires could save ~$100K in 50-truck fleet
Fleets and high performance car drivers may adopt technology but not general public
No fuel efficiency is gained using nitrogen if proper tire inflation is maintained anyway
Nitrogen separators/compressors cost $3-10K in variety of quality levels/longevity
Cost to fill tires w/ pure nitrogen $3-5 per tire
