Article I read a while back stated two benefits to Nitrogen; stable pressure and lack of moisture. Nitrogen will not have any moisture content. If you get air from a poorly maintained pump it could introduce moisture into your tire. Moisture and our TPS do not mix well. Therefore, I run nitrogen in both my vehicles with TPS.

Maybe

 

I went all the way to the 3rd planet for mine. But it's been worth it.

 

Anyone know of a place in TX with readily available nitrogen?

 

If its available to you, it make since, better protection for your wheels tires and sensors, nitrogen has larger molecules than oxygen, will not leak out as fast and holds no moisture. Overall better in every way.

 

FWIW
I watched the psi in my Magnum with the 4 wheel real time monitoring to see how much the pressure swings relative to temperature. Granted the 20" wheel with wider tires is a larger air chamber, but it still proves the point.
The temp swing here in 2 weeks was from 9 degrees to 62 degrees per my dash temp, which has proven to be pretty accurate. The psi swing was from 27-41 psi The heat from driving normally raisies the psi 2 lbs in a 10 minute commute, so use 39 as the top number. That is still a 12 lb swing.

On a lopro tire 27 didn't show an extra bulge and 40 didn't add any harsh feel on a heavy, long wheelbase car. I don't run pure Nitrogen, just the typical mix we all breathe. BUT those numbers do show that in a scenario where inflation is crucial and you aren't **** about checking the psi it could save your **** to run Nitrogen.

Protecting the TPMS is a nice bonus I hadn't considered. Beating the dead horse here brought us another nugget, and a few actual facts to consider

Hate to break it to you, but atmospheric air contains 78% +/- N2 with about 21%+/- O2. Pure nitrogen (N2) is heavier than oxygen (o2) Not sure if I'd want to fill my tires with 99.5% Aviator Breathing Oxygen, highly flammable

 

Nitrogen fill has been used here in Canada at Costco for at least 3 years, zero problems.

Gone are fluctuations in tire pressure, corrosion on beads of wheels.

Cold and heat does not affect the Nitrogen, have placed in all my rides since 2006, will not go back to air. Cross is in storage, getting her nitro'd as soon as she comes out to play. Recommended A ++++

 

From the warranty card on my new Pirelli Snows-

What is Not Covered By Warranty

Tires injected with liquid balancer or sealant or in which anything other than air has been used as the support medium.

 

Most definetily Sealant is not accepted, never has never will,
Nitrogen is not support, it is recommended by the tire industry as it is more stable than air, ensures constant tire thus ensuring proper wear.

Only reason it is not standard is consumers are always looking for cheapest price.

Nitrogen Will NOT void tire or manufacturers warranty
