Nitogen instead of air?

[Scuba_Steve]

was looking in a mag today at new alloys when i came across a lil ad saying about nitogen in your tyres instead of air? i am wondering if anyone on here has tired this? also done my research on google and came up with this link below.

what you think? fought it might have been a good thing to post for the trackday cars unless i am abit late and this is a repost lol!!

all the tyrecentres here use it.. saying it prevents corrosion of the rims etc i could'nt care actually

Pretty sure crisp packets are full of nitrogen.

I breathe in oxygen, and breathe out nitrogen!

I've never tried it, just normal air has done for me.

mine are nitrogen filled.

Aircraft tyres are always filled with nitrogen. I think that's mainly due too how much expansion and contraction you get with temperature change. With nitrogen you get a more stable pressure over a range of temperatures. For example the wheel bay on an aircraft drops to temperatures a long way below freezing and then on landing reaches high temperatures as the stationary wheel contacts the tarmac at speeds over a 100kts.

I would imagine it's used in motorsport applications for the same reason to keep tyre pressures as consistent as possible whether on warm tyres or cold.

EDIT: I really should have read the linked page before posting LOL it makes a better argument than me, although I think i'm sort of right about pressures!!

On the race car we vac out all air to remove moisture and refill with nitrogen. More stable and less affected by temp change making pressures consistent.

sounds like a good idea tbh, is it expensive?

 

[Fred@BTM]

about £3 a tyre

 

[kevinhall]

All tyres fitted at costco are filled with nitrogen. Can't say i've noticed any difference but theories sound good

you breath out carbon dioxide :quiet: lol

 

[ben_p]

as above, costco did mine with it

Aircraft tyres are filled with nitrogen as its an inert gas there for would not burn in the event of a brake fire.

Am i right in thinking that you dont need re-inflate tyres when you fill them with nitrogen?

Helium for weight saving

You will still need to re-inflate them as air/nitrogen will still leak out of them. Apparently it just leaks a bit slower (assuming air only leaks out through the carcass, and there's no loss through the valve!), but I imagine most people would be hard pushed to notice the difference.

When your nitrogen filled tyres go down in pressure, what are you then going to do; use a foot pump, or go back to wherever originally filled them, and get them to put more nitrogen in?

Complete waste of money for road cars and most track cars. Standard air is approximately 78% nitrogen. How on earth anyone can think paying £3 a tyre, to get an extra 22% nitrogen is a good idea, is completely beyond me.

Buy yourself a pressure gauge and check your tyre pressures a bit more regularly!

 

[Scuba_Steve]

mine are nitrogen filled.

were you get urs done? i gonna get mine done like that lol!
*off topic for gary* that metro is getting a new engine 1.8 supercharged soon
