Want to Make Your Tires Last Longer? Fill Them with Nitrogen

SAN ANGELO, TX -- Nitrogen filled tires last 50 percent longer than tires filled with regular air according to a study by the Department of Mechanical Engineering at Clemson University.  

Nitrogen molecules are larger than oxygen molecules so nitrogen doesn’t seep through as quickly.  Nitrogen is an inert, dry gas so there’s less corrosion as well.

According to the Clemson study, nitrogen filled tires maintain pressure 35 to 55 percent better that regular air and nitrogen filled tires help improve tire life and vehicle fuel economy and reduce the overall operating cost.

That means on average consumers will spend less money on fuel and tires last longer.  

The Clemson study says, “All the tests conducted clearly indicate that nitrogen inflation in passenger car tires can improve tire life while improving the fuel economy of the vehicle. Nitrogen inflated tires can maintain tire pressure 74% better than shop air per month at normal operating conditions. As a result, nitrogen inflated tires produce about 70% less rolling resistance than air inflated tires.”
