Benefits of Nitrogen in Tyres
The experts say that there are many very compelling benefits to be enjoyed from the practice of filling your vehicle’s tyres with nitrogen. These benefits include:
The key benefits are a slower rate of pressure loss and cooler running temperature of tyres.
The molecular structure of nitrogen differs from that of air, in such a way that it escapes through the tyre’s inner liner or tube at a slower rate than regular compressed air.
The result is a dramatically slower rate of pressure loss in a tyre filled with nitrogen. For example, it might take up to six months to lose 0.14kpa with nitrogen, compared to just one month with compressed air.
Tyres inflated with nitrogen also run cooler than those inflated with air, with some significant advantages.
One such advantage is an improvement in tyre life of up to 20%, because by reducing the tyre’s running temperature, you can increase its tread life.
Improved road handling is another benefit that stems from cooler running tyres.
As tyres heat up, their inflation pressure increases, which then reduces the size of the tyre’s footprint – the area that has contact with the road – the tyre then loses grip because of this smaller footprint. So the cooler they run the better the tyres will grip the road.
Nitrogen should lead to reduced corrosion – because unlike air there's no moisture in pure nitrogen
Nitrogen and Safety
It is important that we look at the benefits of Nitrogen gas from a road safety perspective:
The facts are clear and there is evidence to suggest that nitrogen tyre inflation is preferable to air inflation. There are compelling facts pointing towards better road handling and improved tyre life of up to 20%...
The top three reasons for blow-outs are poor condition, overloading and under -inflation. Poor condition comes from drivers not being responsible and running their tyres too far. Overloading comes from the same irresponsibility and the law not being enforced as it should be on both counts. We can however do something about under-inflation. The answer might be to fill tyres with nitrogen tyre gas.
Why do we say so?
Compressed air contains water vapour, which accelerates rust, corrosion and damage to wheels, resulting in leaks and loss of pressure.
Water vapour absorbs and holds heat, and when it changes from liquid to vapour, the water expands in volume. So tyres inflated with wet air tend to run hotter and the pressure fluctuates more. Nitrogen has very little water vapour.
As with normally-inflated tyres, it is advisable to check tyre pressure regularly to prevent excessive wear. Regular tyre pressure test intervals should still be maintained, as the tyres on the drive axle of the vehicle tend to lose pressure faster that the non-drive wheel axle.
