Use Of Nitrogen In Pressurizing Car Tyres

Using the Nitrogen gas for inflating the tyres is a relatively new concept. Thus, one should adopt it or not has always been much debatable topic among the auto experts. Nitrogen is basically a non-toxic gas that is tasteless, colorless and odorless gas that accounts for over 78 percent of the earth’s atmosphere. The Nitrogen gas is used in a number of automobiles to inflate the tyres including racing cars, HCVs (heavy commercial vehicles) and even aircrafts. Where some auto experts say that using Nitrogen is beneficial, there are some who says it has many disadvantages. Here we have tried to pin point some of the pros and cons of using Nitrogen gas for inflating the tyres
Pros:-
1) Nitrogen helps in keeping the temperature of tyre low while car is running on a high speed or heavy load. The reason is the high moister content of Nitrogen that reduces the overall running temperature of the tyre.
2) The Nitrogen falls a bit lighter as compared to the normal air which helps in improving the overall ride quality of the tyres because of its lesser un-sprung weight.
3) It has also been claimed that the use of nitrogen enhances the overall engine life in a longer run by reducing the operating temperature.
4) Nitrogen leaks a bit slower as compared to the compressed air and thus the rate of pressure loss falls slower while using Nitrogen.
5) Oxygen causes oxidation and rust formation by reacting with the tyre and rim materials. On the other hand, Nitrogen is an inert gas so there is no possibility of any type of reaction with metal.
Cons:-
1) Nitrogen falls quite costly.
2) As it is a relatively new concept, its filling stations are very low in numbers and are not available in most of the filling stations of the country.
