Filling nitrogen in the tyre stands for a long time when compared to the air filled tyres.As nitrogen is inert, non-combustible, non-corrosive and less destructive in terms of oxidation of rubber, the pressure inside the tubes are maintained for the long time.Obviously the tyre that is well inflated lives longer. TVS is in talks with oil marketing companies to install nitrogen inflators at fuel retail outlets for starters in Tamil Nadu. The Head (operations) of the division of TVS & Sons, Mr R. Seshadri, said that as a pilot project the company has installed nitrogen inflator for cars and two-wheelers in one of the fuel outlets in the city. It will study the viability of the project for the stake holders such as oil marketing companies, fuel retailers and customers. Based on the study the company would work out modalities to expand its operations. The inflating machines will be imported. Nitrogen also helps in improving the fuel efficiency, as the tyre stays fully inflated. Today there are a few nitrogen filling stations in the city. They charge about Rs 40 for a car tyre and Rs 25 for a two-wheeler tyre, to fully deflate the air and fill in nitrogen. For top ups, they charge Rs 10 a tyre. Once the demand picks up these charges will fall.
