Thread: Nitrogen infllation of tyres?

I'm not convinced - after all, air is 78% nitrogen anyway.

BS alarm! BS Alarm!

Great when you have to go to a tyre dealer to check your tyres.

What about if you air down for the beach?

the only time nitrogen inflation is worth it is when you have to deal with the condensates evaporating and changing the tyre pressures...

if there's that much water in the air from the tyre shops compressor I reckon that that's a tyre shop you want to avoid and if you were driving your landy fast enough for that to be a problem you wouldnt have your license long enough for it to be a problem so its moot either way.

I have heard of truck drivers using it in high ambient areas on large rigs such as road trains.
Pressures stay constant,that is hardly fluctuate with temperature,& the molecules are supposedly bigger than air,so it doesn't bleed as quickly.


I wouldn't use it,in a 4WD,but if i was running a rig with say,for eg, 30 plus tyres,it may be warranted.Constant pressures means better tyre wear,etc, which means $

Nitrogen tyre fills have been proven to work, but are only generally usefull in tyres with high temps. Long distance driving and racing especially.
Comparing to nitrogen content in the air is just wrong. Nitrogen placed into tyres is very cold. I would only consider using it in a performance application. It is a waste of money for most general purposes, especially if you are airing up and down.
I have spoken to a couple of truck drivers who use it on their steers (good tyres) and on rear drives if the tyres are new with good results. They dont use it on trailers as it is cost prohibitive, most just use water in their trailer tyres.

........ this is a new one on me for truck tyres!

I used to be a 24 hr roadservice tyrefitter about a decade ago, then elevated to the store manager. We serviced Linfox, Readymix, TDG (now Patricks) among others, and I never put nitogen or water in the tyres.

I did, however, put water in tractor tyres as ballast (weight), back in NZ, and depending on the tyres size, would put 12 liters of metholated spirtits in as well (to act as an anti freeze)

- must be a new thing as I have been out of the loop for a while.

Cant say I'd recommend it for 4x4 tyres.

The difference in gas properties between nitrogen and the dirty nitrogen we call air is so slight that any difference will only be perceptible under stringently controlled conditions. Perhaps noticeable in competition conditions, but even then I would doubt it.

Its major advantage is to separate more money from the customer.

If your going to be changing gas in your tyres then you should go the whole hog and get helium, makes your whole car lighter, draws heat faster and would truly reduce tyre wear
