Nitrogen in tyres?

[Sidders]

Just before I go ahead and buy - is nitrogen worth the extra……has anyone else ticked this box and felt any apparent benefit?

Always used nitrogen in my race/track cars. Complete waste of money on a road vehicle.

If your particular about losing 1.3psi in pressure over a year then go ahead…

Are Nitrogen-Filled Tires Worth the Cost? - Les Schwab

Wondering whether nitrogen-filled tires are worth the money? Here’s your answer.

Great for race cars and aeroplane tyres, otherwise as good a way as any to throw your money away.

Air is 79% Nitrogen.

You pay a lot for that extra 21%.

Considering the air we breathe and inflate tyres is already 78% Nitrogen I see no point in paying. Although I do understand the advantages for racing tyres.

Better off with Helium - it would increase your payload

 

[David and Sally]

What is the advantage for racing tyres please?

Ignore. Googled it.

 

[Coolcats]

Hydrogen will give more bang for your buck though

As a fire precaution for aircraft, wheel fires, although not that uncommon, may be due to the high landing speeds and pilots needing to apply full braking on landing or anti- skid faliour. Also you know the nitrogen is dry so less risk of the alloy wheels corroding.

Even though nitrogen passes through the tyre wall slower than does oxygen, it still passes through. So at some point the tyre will have to be inflated which will mean taking it somewhere where it can be inflated with nitrogen - not very practical.

I believe Hydrogen is more stable on pressures ie: when the tyres get hot they do not vary so much in pressure like tyres filled with air

 

[Lenny HB]

How are you going to adjust your tyre pressures on a trip?
Offen adjust mine both up & down a couple of times sometimes more often on a 6-7 week trip as temperatures vary.

I’m not sure about that. Gay-Lussac’s law states that for a given volume (for example inside a tyre) the pressure is directly proportional to the temperature for an ideal gas which nitrogen, oxygen and hydrogen all approximate to under normal conditions. So no matter which gas you have in your tyre, the pressure will rise by the same as the temperature increases.

One reason why the pressure may not increase so much with hydrogen is that it probably leaking like a sieve out of the tyre. Hydrogen is a much smaller molecule than oxygen or nitrogen and will have much less trouble finding its way out between the polymer molecules in the tyre
