Nitrogen filled Tires??

take it u rebuild bypass shocks??

Motorcycle....emulsion and de-carbon style

What ever happened to the good ol' days when we used a trusty red tire pump? And what the heck does "angel crying on your tongue" mean anyway?

LOL....mine is black though..

Lets weigh the cost here

$40 bucks for nitrogen fill that has to be refilled every 3 months OR


$0 for free air that has to be checked every month








Tough decision

ahhhhhh Sarcasm the lowest form of wit " But the Best "

OK, I can't take it anymore: Just to clear the air (so to speak).

Air is roughly 80% nitrogen and 20% oxygen (It is actually 79% Nitrogen, 19% oxygen, and about 2% everything else: CO2, neon, argon, etc). Pure nitrogen expands with temperature almost exactly at the same rate as air. Both fairly acurately follow the ideal gas law equation PV=nRT.

So, yes nitrogen expands with temperature, just as regular air does and at almost exactly the same rate.

The main thing that makes air tend to vary more than pure nitrogen is that typically the compressor used to fill up your tires has some water vapor trapped in the tank and gets put into your tires. The same thing happens when you use your own little 12V compressor plugged into your lighter outlet. If the humidity is 80% outside when running your compressor, that's what gets put into your tires, air at 80% relative humidity (which is only a few percentace points or so of water vapor). But, a little bit of water vapor can make the tire pressure vary much more with temperature.

Nitrogen dispensed out of cylilnders typically is very dry, so it tends to not add any water vapor into your tires. However, you could achieve the exact same thing by putting a desicant chamber on your air hose from your compressor to remove the water before it enters the tires. Inline desicant chambers are used for paint spraying setups where water vapor would have a negative impact on things like an automotive finish being sprayed by a paint gun. I have a desicant chamber on my home compressor. I think it was around $30

The other advantage that dry nitrogen has is that it will not oxidize the rubber, since it contains no oxygen. However, this is kind of a mute point since the outside of the tires are sitting in regular air....

The whole nitrogen thing is somewhat of a scam. If the service station would just use an inline drier, we would be all set.

No differnt than a good body shop spraying paint without a moisture catcher then :dontknow: :dontknow: :dontknow: I got it thx for clearing that up, I guess my kid got fucked and Dad paid the bill:marchmellow: :marchmellow:
