Nitrogen - N2, is a fairly stable gas with higher molecular mass than oxygen. In it's pure form it will not react to rubber nor metal parts without any catalyst. It's more resistant to volume fluctuation due to temperature changes than compressed air. Purified nitrogen gas also has less moisture content that may contribute to corrosion on metal parts. Nitrogen's molecular size is bigger than oxigen's so it's slower to escape from very small tire punctures than compressed air but this is probably negligible. Benefits of using pure dry nitrogen on tires are increased mileage and better tire wear.

Mga bosing na gumagamit ng Nitrogen gas, baka naman pwede nyo i-share experience nyo on the use of nitrogen gas. = )

Thanks
