Atmospheric air is mostly composed of nitrogen (78%), so chemically there is not much difference between compressed air and compressed nitrogen. The reason compressed air is not used in racing tires is that racing tires operate at temperatures above the boiling point of water. And since compressed air contains water vapor, the water vapor in the tire's air would turn to steam during a race. The water vapor's latent heat phase change would cause a rapid increase in the tire pressure, upsetting the handling of the Vehical. Dry nitrogen has no water vapor present, so a tire inflated with it is much more stable over the tire's operating temperature range.
Nitrogen molecules (N2) are larger than oxygen molecules (O2) so therefore, pure nitrogen will permeate the walls of your tires less than oxygen molecules.
Advantage of nitrogen in tyres:
- Nitrogen is lighter than air. So, the bounce you feel sometimes at high speeds is reduced to a very great degree. This translates into a smoother ride for you.
- Nitrogen gas remains cool, which is a characteristic trait of the element. So the temperature of the tyres while riding at high speeds also remains cooler compared to air.
- The tyre pressure remains constant at different speeds regardless of heavy / light load on the vehicle. It remains quite stable regardless of the temperature of the tyre.
- The life of the tyre gets an extension. Since the wear and tear has slowed down, the durability of the tyre increases.
- There is also a noticeable reduction in rusting of the rims or wheel as nitrogen is chemically inactive.
- The rate of nitrogen pressure leaking from the tyre is 10 times less than the compressed air. So one can fill the tyres with nitrogen gas and then check the pressure again after 3-4 months or even more.
There are not many disadvantages of nitrogen in tyres but those that exist cannot be ignored.
- The process is expensive. it cost approximately Rs.20 for a two-wheeler for first time. later on refilling costs around Rs.10
- Even today the gas is not available widely. Only few petrol bunks provide it.
- It’s useful for high speed bikes. Compared to the amount of commuter bikes the ratio is fairly low.
- If a tyre gets punctured, after repairing the puncture, you have to repeat the process of filling nitrogen in the tyre.
