Many tyres prematurely wear out because of under-inflation. Tyres which are low in pressure wear out the edges and this can reduce the life of the tyre by up to 50%.
Having the correct air pressure in your tyres not only extends the life of the tyre, but also makes the car safer on the road, especially in the wet.
Tyre pressures should be checked every 2 to 4 weeks, as the oxygenin the tyres will naturally escape over time. The reason for this is because oxygen molecules are small and can easily pass through the rubber compound of the tyre.
It’s hard to remember to check the pressures and we are so time-poor these days, I mean who has the time, to find the time, to check the tyres. And who ever checks the spare wheel?
The solution? Nitrogen.
Nitrogen disperses three to four times slower than compressed air. It is largely because of this, that a tyre inflated with pure nitrogen has numerous benefits:
Increased Tyre Performance
When correct tyre pressure is maintained, a pure nitrogen filled tyre assists in maintaining the correct pressure for longer. This is because nitrogen molecules are larger than oxygen molecules, making them more resistant to leaking. Therefore, pressurised nitrogen stays inside a tyre longer, unlike oxygen, which escapes more readily over time. Correct tyre pressure improves the performance, durability and contributes to the overall fuel efficiency of your vehicle.
Greater Tyre Life
As an inert gas, Nitrogen is non-reactive and property free. This means that there is minimal moisture content, making oxidation less likely to occur. Water (moisture content) inside a tyre can cause internal corrosion. It can also affect the pressure of a tyre with changes in temperature. A cooler running tyre slows the rate at which a tyre wears, therefore increasing the overall life of the tyre.
To experience the associated benefits of nitrogen filled tyres, you must continue to fill them exclusively with pure nitrogen. Remember, that whilst nitrogen takes longer to escape a tyre, using it does not eliminate the need to regularly check your tyre pressure.
However, with nitrogen you would only then need to check the tyre pressures about once every 4 to 6 months!
