free nitrogen tyre inflation

is on at costco if you are a member;), for free !!!

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

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

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

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!

Cool (get it) :grin:

use it on aircraft for the moisture reason

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?
