[T3] Tire failure?

[Daniel K. Du Vall]

I used to work in the high purity gas control industry so the Nitrogen I
am used to always came in liquid form from dewars. Getting it form a on
demand machine seems to me like it would not be of good quality. I guess
for tires it really does not matter. It is more stable than normal air
in that its expiation rate is less I guess that would be good for gas
mileage if your changing altitude a lot ;-)

I think they have a set up similar to this one.  As you can see they are

not cheap.  I've seen some compressors like this more than the one here.
