Flying Tyres

nitrogen inflation of car tyresA SIGN CAUGHT MY ATTENTION WHILE GETTING NEW TYRES.

It was the bottom entry on the list of inclusions — Nitrogen inflation.

I had never heard of that — I always assumed that car tyres are filled with common or garden air.  Nitrogen gas just seemed a tad excessive.  I looked it up on Wikipedia when I got home, and sure enough, Nitrogen is used — for aircraft!

“Aircraft tires are usually inflated with nitrogen or helium in order to minimize expansion and contraction from extreme changes in ambient temperature and pressure experienced during flight…
…The use of an inert gas for tire inflation will eliminate the possibility of a tire explosion.”
en.wikipedia.org/wiki/Tire#Inflation_pressure

Things are definitely getting worse when a common, everyday car tyre gets filled with Nitrogen gas! The world has gone mad!

    For passenger car applications the main claims seem to be

    Reduced corrosion – because unlike air there’s no moisture in pure nitrogen
    Slower rate of pressure loss – because nitrogen molecules are larger than oxygen molecules (which make up 21% of compressed air)
