free nitrogen tyre inflation

what's the deal with nitrogen filling then? i.e. what are the benefits?

[uk-rich]

its doesn't expand when hot, carries no water vapour , the F1 guys use it

[Havard]

It also makes the car lighter.......

 

We use nitrogen when filling pressure vessels on heating systems. Never thought about putting it in my tyres though!!

... then realised that was hydrogen

[Ric]

but you posted it anyway, didnt u.

yeah, im bored... sue me

I like it...

Air is 80% nitrogen! Nitrogen is only marginally lighter than oxygen! It expands and contracts just like every other gas.Draw your own conclusions!

[Ian R]

Cool (get it) :grin:

[supradibbs]

use it on aircraft for the moisture reason

[robin]

I believe but may be completely wrong that normal air in large commercial jet tyres would cause blowouts. I think the nitrogen is an inert gas and therefore doesn’t react or facilitate burning like a 20% oxygen mix might.

yes plus expansion of running about 230psi but the air in normal tyres can carry moisture at -50 temps this could cause havoc

Filling automotive and aircraft tires[2] due to its inertness and lack of moisture or oxidative qualities, as opposed to air, though this is not necessary for consumer automobiles.[3][4]

Nitrogen molecules are less likely to escape from the inside of a tire compared with the traditional air mixture used. Air consists mostly of nitrogen and oxygen. Nitrogen molecules have a larger effective diameter than oxygen molecules and therefore diffuse through porous substances more slowly.[5]

Does it mean your tyre pressures will remain more constant then?

 

Is that the only key benefit?

Yep. That's why they use it in F1.
