Nitrogen in tires

[Gene]

Just changed 4 new tires and I was given the option of filling it up with Nitrogen instead of compressed air.

On my first tank, got better fuel economy ~ roughly about 5-10% more. (But it could be due to the new tires)

It says that it'll give better lifespan for the tires, anyone with any experience with nitrogen in tires?

Whatever they tell you, it's bull****.

I assume that you didn't maintain your last tyres and check the tyre pressures on a regular basis? This is why you have noticed an increase in fuel economy.

Nitrogen in car tyres is a waste of money, there have been a number of threads on here that have gone into detail as to why but;
- Air consists of 78% nitrogen, oxygen is what permeates out of the tyre so when you refill with air each time you end up with an increasing volume of nitrogen.
- The losses over time between nitrogen filled tyres and air filled is minimal.

The only benefit is that you can get some moisture in the air at the service stations which can cause corrosion under some rare circumstances (well the other benefit is that you make the shops that sell this rich).

Better to check your tyre pressures on a regular basis and invents in a direct TPMS system.

... and heaps more info in the General or Wheel and Tyre sections of the forum; just need to search for it.

Differences are minimal, filling it up with Helium... now that's an idea

I use Hydrogen, it's half the weight of Helium.

I'd love to give input on this.. But last time I did I got banned.

Lol... make sure you're not in a crash if you've got your tyres filled up with hydrogen!

Thanks I found the thread I was looking for now - http://www.vwwatercooled.org.au/f27/...gen-33600.html.

Heaps of info on the pros and cons of Nitrogen in tyres and as a bonus the thread that saw Preen59 get banned

Ha, one of a few.

I guess I just don't like authority.
