Nitrogen gas in tyres

Filling nitrogen gas in tyres

In India filling nitrogen gas is not very much common. But in the other countries they filling of nitrogen in tyres is very mych common. From the past many years itself rcing cars, aricrafts, and even the space shuttle is using nitrogen in its tyres. There are so many advantages and disadvantages of filling nitrogen in tyres. Also in India there is another factor also - whenever so many people are trying one thing then only others will come into use with it. Likewise Indian are not much aware of the nitrogen filling procedures and how to maintain it. But in so many petrol pumps in India also instead of air there is nitrogen filling apparatus is also provided. During puncture ther is the problem exists. ie, When a problem of puncture occurs there is not any nitrogen gas available at ordinary shops. So the wastage of time and money will occur. Anyway by filling those nitrogen gas there are some advanatages and disadvantages. Some of them are....

Advantages

  • Nitrogen reduces the running temperature of the tyre. The moisture content of nitrogen leads to a cooler running tyre, which is advantageous when the car is operating at its maximum load and speed capacity.
  • Nitrogen in tyres improves the ride quality. That gas is very slightly lighter than air and thus, benefits the tires in terms of un-sprung weight.
  • It is assumed that Nitrogen increases tyre life. It reduces the operating temperature during times of load and speed and thus, enhances the life of a tyre.
  • It is believed that nitrogen keeps tyre pressures more constant. The gas is assumed to provide more stable pressure range in connection to the tyre temperature. However, again, the factor is applicable in times of heavy load/high-speed conditions.
  • Tyres are susceptible to loss of pressure as a result of being porous in nature. Due to its chemical structure, Nitrogen leak out slowly as compared to compressed air. Therefore, it slows the rate of pressure loss.
  • Oxygen reacts with the tyre and rim materials causing oxidation or the rust formation in the metal parts. Nitrogen, being an inert gas, does not react with the tyre and rim materials.

Disadvantages

  • Inflating tires with Nitrogen is quite costly. The cost generally comes to somewhere around 25 to 50 per tyre for a passenger car.
  • Filling tyres with nitrogen requires more maintenance as compared to compressed gas.
  • The availability factor is the biggest disadvantage of inflating tyres with nitrogen, as the gas is not readily available. It is usually found only with specialist tyre dealers.
