Do dealers actually put nitrogen in tires?
To lower the number of times you need to fill your tires, some consumers and dealerships will fill the tires with nitrogen instead of regular compressed air. The key difference is that regular air contains moisture and other contaminants that can affect tire pressure and longevity. Nitrogen results in a more stable, dry gas inside the tire, reducing pressure fluctuations and minimizing internal corrosion.Maintenance: If you need to top off your nitrogen-filled tires, it’s best to use nitrogen, as adding regular air could dilute the nitrogen’s purity and negate some of its benefits. However, mixing small amounts of air won’t significantly affect the tire’s performance.
Is it okay to put air in nitrogen-filled tires?
Let’s face it; if you’re on a road trip and need to air up a nitro-filled tire with oxygen, you can do it safely. Contrary to myths floating around out there, mixing them will go unnoticed to you. Over the long haul, however, the oxygen will reduce the effectiveness of the nitrogen almost completely. Nitrogen is touted as the best gas for tyre inflation among the gases by the size of the gaseous molecule: because it is larger, it loses pressure much more slowly. Plus, it reduces moisture, thus minimizing tyre and rim corrosion.
