As we’re all aware, inflating tyres is crucial in maintaining grip, handling, and overall vehicle safety, especially in challenging road conditions.
This maintenance process involves you filling your tyres with normal air.
While it might sound odd to call the air used for tyre inflation “normal,” there’s a reason I’m making the distinction.
That reason is nitrogen – a gas that’s been gaining popularity as an alternative for filling tyres, thanks to its unique benefits.
Unlike regular compressed air, which contains a mix of oxygen, nitrogen, and other gases, nitrogen inflation offers advantages such as improved pressure retention, reduced moisture buildup, and potentially enhanced tyre longevity.
But what exactly makes nitrogen different, and is it truly worth the switch? Let’s explore.
What is nitrogen?
Simply put, nitrogen is a gas that makes up approximately 78% of the air we breathe.
It’s dry, stable, and doesn’t react as easily with other elements – especially moisture.
That’s why it’s often used in industries where consistency and durability matter, like aviation and motorsports.
When it comes to tyres, nitrogen’s biggest selling point is that it leaks out more slowly than regular air, helping maintain pressure for a little longer.
But does that really make a difference for everyday drivers? Let’s break it down.
