Re: Nitrogen in tires????

Try again. One can mix oxygen with a fuel but it still will not burn.
Search a bit more, WBMS. ;)

No. "So nitrogen isn't an inert gas. Granted, it doesn't react like oxygen
and methane gases, but it is not inert, either." <react substituted for
burn> is totally accurate. My reference forth is any high-school
chemistry book.

Get a clue, if you can.

I should have said "reacts."

You can prove it to yourself. Turn off the oxygen, on a burning
oxy-acetylene torch, and observe what happens. Then turn off the
acetylene, on a burning oxy-acetylene torch, and observe what happens.

To give you an example concerning tire pressure / inert gases, the
subject of this post, let's say that the limitation is 195 lbs. +
or - 5 psi. on a nose tire. This is derived from aircraft
certification testing and tire manufacturer operational
specifications. The nose tire has to perform several functions of
course, a couple of them being steering or directional control, and
deflection of foreign objects / contamination to avoid engine
ingestion and airfoil lift degradation. Directional control can be an
issue on a contaminated runway (slush, rain, ect.) where hydroplaning
comes into play. Higher pressures directly equate to higher speeds
that you can maintain directional control before hydroplaning, and
that is an issue at 140kts landing speed. If you look closely at a
nose tire on an aircraft with the power plants mounted on the rear
especially, (some wing mounted) you will notice a thick rubber lip
molded on the entire outside sidewall of the tire. This is called the
"chine" of the tire. It's function is to deflect contamination well
clear of engine inlets and airfoil surfaces on both takeoff and
landing. You can imagine the force of just 1/2" of slush against the
outer surface of the tire at takeoff or landing speeds. Main tires
must transfer all of the kinetic energy built up from aircraft
movement to the surface through braking, either on landing or an
aborted takeoff, resisting all of the heat transfer of the brakes,
maintaining carcass integrity, and friction coefficients. They can
get so hot that "fuse plugs" are built into the rims, so when
pressures and heat become so great, the plugs "blow" and the tire
assembly is deflated prior to exploding off the rim and potentially
injuring or killing someone. An inert gas, usually dry nitrogen is
used because of it's relative cost being inexpensive and it's ability
to resist molecular movement / expansion at temperature extremes.
Sorry if I went on too long and this is too much information.
Just a technical note: Nitrogen is not an inert gas. Inert gases
include helium, argon, neon and xeon. They are elements that don't
react with anything. Nitrogen does react with oxygen (that's why it
from nitrogen oxides in your engine), hydrogen (making ammonia) and
other things (which is important for proteins, DNA, RNA in your body,
all of which have nitrogen in them).

So nitrogen isn't an inert gas. Granted, it doesn't burn like oxygen
and methane gases, but it is not inert, either.
