Why Are People Filling Their Tires With Nitrogen And Should I Do It Too?

One of the main arguments for nitrogen-filled tyres is its ability to withstand a slower rate of pressure loss. As nitrogen molecules are bigger than oxygen, they don’t run the risk of escaping your tyres quite as easily.

I hate all the science jargon just as much as the next guy / girl, but simply put: purely nitrogen-filled tyres are theoretically built to stay inflated longer than your average tire.

Also, this type of tyre would be less prone to corrosion. Let me explain this in the simplest way possible. (Bear with me here.)

All you need to know is that corrosion tends to occur in the air-filled tyres mainly due to the fact that moisture is available in air.  Moisture is one of the key catalysts for corrosion, and lo and behold, it is not available in pure nitrogen.

So essentially, what you are getting with nitrogen tyres is a smoother ride (fuller tyres), and tyres that are built to last longer (less corrosion). Sounds like a pretty good deal to convert to believing in pure nitrogen and all of its glory right?

Well, we’ll let you be the judge of that.

Should You Be A Pure Nitrogen Believer?

Sure the tyres might have a slower rate of pressure loss, but if they don’t improve your experience in any way, shape or form, then what’s the point?

When tested and applied in the real world of driving, there didn’t seem to be much difference in the performance of a car with air-filled tyres as opposed to purely-nitrogen filled ones. The guys at the ‘Fifth Gear’ television series went on to test the theory of the so-called ‘amazing purely nitrogen-filled tyres’, but simply could not find any tangible benefits when applied on the road.

From the speed of the car, to the actual driver’s experience, there did not seem to be any difference between the effectiveness of the nitrogen-filled tyres and the air-filled ones.

Sure, in theory there could be a thousand and one benefits listed on paper, but all those benefits are blown out of the water if they can’t deliver concrete results to whom it matters most – you, the driver.

To sum it up, purely nitrogen-filled tyres does have its benefits, but these benefits may not be as great as you thought it was after all.

It really does depend on the individual and their preferences – some are hell-bent on defending the notion of pure nitrogen, swearing on all its wonderful attributes (they are being used by the elite racers of the world after all.) While some might feel that they are simply overrated.

And that’s the catch: you have to test them out for yourselves to figure out if they add anything to your driving experience, as experience is one of those things that is purely subjective.

The only way to truly find out if they’re right for you, is to try them out for yourselves and see if they’re really all worth the hype. Maybe for you, the couple of quid you spend on nitrogen gas the next time round turn out to be the best driving investment you’ll make in your life. Or perhaps you’ve just wasted a couple of quid on something that didn’t pan out the way you wanted it to.

Either way, you’ll be able to impress your clueless family members on how you have the latest F1 technology in your tyres.

Whatever makes you happy.

  1. Air is 79% Nitrogen, about 20% Oxygen. IF the Oxygen diffuses through the tire when you top up, you put in more 80 20, and eventually reach 100% N, plus, of course, some moisture. I personally think it is a marketing ploy.
