My tire shop told me about a new technique where they fill the tire with smoke from burnt C notes. It's expensive but worth it.

You should try a 70% nitrogen 20% air mixture. Is the best

Space oxygen is the best, the oxygen molecules slow down in space and never move , so if you have space oxygen in your tires, you will never lose any air.

100% the hook for selling nitrogen for filling tires is that the larger molecules take longer to leak out of the rubber tires ,


The hook is moisture related. Nitrogen is pure and inert and doesnt have the moisture content vs normal air. Its hard to up-sell dry air considering most good shops already have a dyer for their tools in the air system.

The moisture in the air cause the fluctuation in the tire pressure. So when its cold in the morning without the moist air your tires stay about the same PSI vs thhe opposite with regular wet air, then pressure increases as the temp raises. They all leak out of the tires at about the same rate.

But there’s no gravity in space oxygen so your truck might float away

Even more when you light it.

Helium is a nobel gas and doesn’t burn.

I would use 78% nitrogen give or take 1% argon.

That is, of course, a legitimate concern. But on the plus side, there's little to no wind resistance so you get infinity miles per gallon of gasoline.

My car has air. Fluctuations in pressure are common. I have to refill at least every 6 months.
Wife’s car has nitrogen. Never had a low pressure alarm in 4 years and never had to refill it.

I can say with certainty that the vast majority of shops do not have clean dry air coming out their compressor system. Your fortunate to even have an aftercooler on the compressor much less a dryer. And tire shops are cheap as shite, and most aren’t going to buy a nice compressed air system that is dry. Unless they paint, they could care less about a dryer, and even those that paint sometimes don’t care.

Right, cause you get to your destination so much faster and stop burning gas. It’s so much eco friendly.

Do you really trust they are refilling your tires, or even filled them in the first place, with nitrogen?

unless your F-150 has wings and is pressurized, or you live in Alaska, hype

Hardly anyone has nitrogen anymore.
There was a big push for them years ago. a bunch were sold. Problem was the people that were selling them, they didn't know anything about them, and couldn't fix them, so when they broke, they rarely ever got fixed, and over time people just quit buying them.
They aren't cheap, at least the ones that are worth a shite.
