Nitrogen in tyres

[Mike.Gayner]

Doesn't happen, so somewhere that theory is flawed, but you've given me an idea for a test using the nitrogen measuring gadget thingy to see what does happen if I can lay my hands on one

Once again, how do you reconcile that with reality?

Not that you have to when you're living in a fantasy world.

My practical real world experience is reality, whch is a bit different than you just making shit up on the internet

With a blunt axe?

You need still need to reconcile the two points you're making though. You claim the oxygen leaks out of the tyres, but refuse to accept that this leads to a high concentration of N2. How can both of these things be true?

Use Helium. Tyres are lighter, but they sound funny.

I heard that the original Mach III had a helium filled front tyre, it caused a lot of handling problems and quite a few riders were killed...so later models reverted to just air.

I use the green caps for a colour contrast on my bike.

I wouldn't use nitrogen in anything other than a fairly high end racing vehicle.

Waste of money IMO. Just ride the fucking thing and enjoy it.

Have used nitrogen in truck tyres for years. Less leak down and longer tyre life, and yup that's using the exact same tyres with air previously and then going to nitrogen at new tyre fit time. Normal service life top ups done with air. Practical experience suggests it works rather well. And note I was a sceptic prior to first hand experience.

Tried it in the car, difference not as marked...but the car feels different driving on nitrogen filled tyres. Using slightly lower pressures to make tyres wear square or flat, and less leak down is the main difference noted. Fuel economy is slightly better, but hard to pin down to exact numbers.

Never tried it on a bike as yet...doubt it offers any tangible advantage on normal road use. But no harm in trying I reckon, just gotta experiment a little with pressures.

I've got it - the O2 molecules must be holding the door open for the N2 molecules to escape. If the tyre is just N2, they can't get out! Because of this the tyre ends up with a higher O2 ratio thus allowing the N2 to get out quicker. So for best results, flatten your tyre completely before refilling to restore the ratio

Does your brain hurt when you try thinking?

We have run Nitrogen in the Super saloon for about 5 years now, run a separate tank in the truck and all fitting and topping up is done using it. For us the major difference is a complete lack of Tyre pressure expansion/increase, which on really big wide feet is very important it definitely works for us and luckily it is a fully sponsored product so no cost.
Our right rear Tyre lasts nearly twice as long now as it used to simply because having the Tyre entirely filled with nitrogen keeps em cooler and stops them burning off the vital tractiony stuff on the outside.

Has anyone here filled their tyres up with Acetylene or LPG? Heard that it extends the tire life by up to 5 million percent...

Fucking argon master race you pussy!

Supposedly lower leak rate than N2 as well...

I have a big bottle or argon up in my shed, argon is a heavy gas though. It has better shielding properties than n2 though. Helium has the best penetration properties for welding but is hard to get, almost as hard as a bottle of wine for under $9.

Has anyone put that in their tyres? Weight savings over standard air would be simply phenomenal...

Helium is a well small molecule, that's fuck off real quick.

Hmmm, gives me an idea though; argon/helium blend. The spin would force the argon out to line the tyre, while the helium sits on the inside against the alloy where it ain't escape.
