2010 Gen III nitrogen in tires

Perhaps you could patent your process and sell it to others. In that way, you could profit from all of your hard work. :madgrin:

 

I tried helium, but it made the Nav Lady's voice squeaky.

But at least she was probably more fun to listen to.

 

It can be quite funny to change the satnav language.:blabla:

 

That's my favorite blend, too. In fact, I even use it for breathing as well.

 

I have the HVAC systems in my cars and house set up to deliver that mix too. You do need to exercise some care because a wide variety of material will burn in that gas mixture if there is an adequate source of ignition.

 

I recommend using "air." It's available and inexpensive, although car dealers will charge extra. Helium should not be used: It's a precious natural resource and when it's gone it will be hard to get more without mining the sun or Jupiter. Using uranium hexafluoride as QBEE suggested is also a bad idea. When tires are rotating rapidly, the centrifugal force concentrates the fissionable isotope of uranium and you will be running an unlicensed enrichment plant and be subject to the non-proliferation treaty and hauled before the United Nations. (Sulfur hexafluoride is a possible substitute here.)

But really, air(TM) is the most convenient and inexpensive. I can offer you a good deal.

Being pedantic, there is no centrifugal force in this situation.
