I have seen that one Spence....and I totally agree with what he is saying and have advised my customers as such for years.

Very interesting Spence. I have never believed in Nitrogen theory since the being. Now I know why!!!

Around here it is only the major tire chains which push the nitrogen. All the other mom & pop shops never use it. This says a lot in regards to the chains who want you as repeat customers and milk you at the same time!!

As a side note: I really like John's bluntness in his presentation. No holding back how he feel ;D

I've been running a nitrogen blend in my cars for as long as I can remember. Has worked out great so far

Me too. I find that 78% works best.

I like playing with the oxygen level, I have found that 16% is the best :D
Seems better when the wind is blowing from the North 8-)

The funny thing is the public believes this horse !!!!!!!  Guess that's where this guy comes in to set it straight. :)
Also we have to set the public straight. :)
Good video, thanks for sharing Bob. :)

Opps, Spence shared the video, thanks Spence. :)

Yeah sure give Bob all the credit!   [smiley=tongue.gif]

Glad you liked it.   :)

Somewhere in the world, somebody thinks forcing air into a bladder is troglodyte.

Don't all the race car crews use nitrogen in their tires?

His point about molecule size caught my attention. More research would need to be done on that one.
First a molecule can be larger in one dimension but be very thin looking at it from a different angle. R134a and R-404a refrigerants  leak like crazy because they are long and skinny, allowing their escape. But measured in their longest dimension are larger than their predecessors.
I have never used nitrogen in my tires,but the lower pressures and smaller leakrate would be important to some.

All... No. A certain percentage yes but more for the dryness of it which can also be had with normal compressed air. I setup road and drag cars. Some of the side walls are so thin they can be seen bubbling if you spray them with soapy water. The belts make them strong not the extra rubber. They like to dissipate heat out the side walls. It is a big reason the air is adjusted just prior to the race.

You are describing compound molecules. Fuel molecules for example are designed in different shapes to slow down the burn hence octane. The O2 and N2 don't really fall into the category.

I use the compressed air that is dry from our shop system. I normally see less then 1 psi difference between services which can be 3 or 4 months apart.

Just my take on it that's all.  8-)

Hi Spence

  Just googled "compare nitrogen molecule to air molecule", and found an article named. "Are Nitrogen Molecules Really Larger Than Oxygen Molecules?". Doesn't change my decision to come to the same conclusion as yourself, i'am sticking with air at this end.  regards John
