Nitrogen in tyres.

[Sydneykid]

I understand that. I was pointing out that Sydneykid's analysis of making the tyre hot to allow the water to 'split into nitrogen and oxygen' is totally incorrect. That doesn't happen.

Sorry typo on the nitrogen, of course it should have been hydrogen. Thermal decomposition (disassociation by the application of heat) of water happens but at temperatures higher than a road tyre is ever likely to reach. The water vapour pressure climb is what we are attempting to avoid with nitrogen.

All of the race cars that I look after run nitrogen, but there's atmospheric air in my road cars' tyres

this video is excellent and definitely worth the watch

has snake oil written all over it.

It's not that terrible an idea for people who treat their car as an appliance (nor the spare which hardly anyone pressure checks)

Air is 78% nitrogen and almost 21% oxygen - how much of a benefit are you going get from 100% nitrogen on the street?

It's a real pain having top up at the company you purchased the tyres/nitrogen from and during business hours

You can actually achieve just as good a result as nitrogen by using dry air
Use a coalescing air filter and desiccant dryer system after the compressor (like the spray painters use)
But again - street benefits are low
