Using nitrogen vs air in tires

[wdw412]

Has anyone used nitrogen vs air in their tires yet?

More consistent tire pressure.
Reduced wheel corrosion.
Prevents inner-liner rubber deterioration due to oxidation.
Tires run cooler.
Increases tread life.
Increases fuel mileage.
Helps prevent uneven wear .

Oxygen in compressed air permeates through the wall of the tire, thus reducing the tire's inflation pressure. During it's journey through the tire wall, oxygen oxidizes the rubber compounds in the tire, causing under-inflation and deterioration of the rubber . Dry nitrogen will maintain proper inflation pressure and will prevent auto-ignition, will not corrode rims, extends valve core life, and will help the tire to run cooler.
Experts in the tire industry indicate that oxidative aging is one of the primary causes of decreased tire life. Oxidative aging is caused by the diffusion of oxygen from the pressurized air cavity of the tire to the outside atmosphere. Tests have shown that if tires are inflated with nitrogen, there is a significant reduction in tire failure.

I've used nitrogen in my Expedition tires for 2 years with no problems and plan to do the same with my smart car.

The tread will be worn out long before the oxygen rots the tire. Most leaks are from a poor fitting tire bead and not permeability. Leave nitrogen fills to the race drivers...
Anyway, air is 78% nitrogen and it is free

Yes, thats true!


Has Anyone though about Hydrogen or Helium, maybe you can save a penny or two at the pump? Hehe

Just what we need Hinden-smarts with exploding tires...

The gasoline in your tank s many times more explosive than Hydrogen.

Besides - the car would be lighter

Are you Gentlemen, talking about laughing gas?

[fuelpincher]

No, we are breathing it...

The original post had the word Dry in it and it is dry nitrogen that makes it worthwhile. The water vapor that goes along with your gas station air pump that causes most problems. The only down side is you become dependant on a source to top up.

Costco in Washington fills (and will top up) with nitrogen for free if you buy your tires there.
