Nitrogen-filled tires lost an average of 2. The results show that nitrogen does reduce pressure loss, but the reduction was only a 1. We have concerns that car owners who use nitrogen might check their tire pressures less often. That would be a mistake, Pszczolkowski says.
The government agency concluded that using nitrogen does reduce tire degradation by limiting oxidation. Oxidation refers to the damage caused by exposing tires to the oxygen in regular air, which can make rubber become brittle.
However, this is not a practical concern for most consumers, because they replace the tires long before degradation is a problem. In our experience, passenger tire service life is dependent on both wear how even it is and how many miles a tire goes and age. Tires are designed to be used with air, and degradation is not a problem for regular tires used and maintained properly.
Nitrogen may aid this because it seeps out at a slower rate. Pressure changes over time, with temperatures affecting the air density and the air permeating the rubber. Check tire pressure once a month, when the tires are cool in the morning, and top off as necessary with regular air. There is a stronger case to be made for nitrogen for high-tire-pressure, heavy-duty applications, ranging from large commercial trucks to airplanes. But based on our experience with passenger cars and these test results, consumers would be better served—and would save their money—by just using air in their tires and checking them monthly.
