Nitrogen in tires

[Motorace]

We use nitrogen in tires because it is a clean gas. It contain no contaminents that may harm the air chamber of the tire.

Hauling those tanks around is a pain during race support. It would be much easier to use a compressor using outside air.

Heck, Ed is probably using Hydrogen. Helium is too heavy!  ;D

Oh the humanity!

Just for fun, I filled my front tires on my F350 with Nitrogen late fall and left the back with compressor air.  Checked them when the temperatures dropped in November.  Fronts were at 55 psi where I had set them rears were at 48 psi, one was actually 45 but found out I had a really small leak in the valve stem when it was filled (weird).  But the small Nitrogen tank costs little (was given to me) and for 5 bucks I can get it refilled locally.  But wiith 2900 psi it takes a lot before it needs filling.

I had braided lines made to fit the regulator from O'Reilly for 8 bucks so it can reach out of trailer (35 ft.

But I have no idea if it will really matter in lower volume bike tires.

Actually any of you dunlop guys at the midwest rounds we were at had nitrogen in your tires. That is all we used there.  Jim
