Nitrogen Filled Tires

Most tires are filled with compressed air.  However, some tire retailers have started to put nitrogen into their customer’s tires.  Air is a combination of roughly 78% nitrogen, 21% oxygen and 1% miscellaneous gases and water vapor.  The nitrogen put in tires is simply “dry air” with the oxygen removed.

Why Use Nitrogen Filled Tires?

There are several compelling reasons to use pure nitrogen in tires.  First is that nitrogen is less likely to migrate through tire rubber than oxygen.  This means that your tire pressure will remain more stable over the long term.  Also, tires filled with nitrogen rather than air also exhibit less pressure change with temperature changes.  That means more consistent inflation pressures as the tires heat up while driving.  Plus, as the temperature outside changes the inflation pressure, in your tires, will remain the same.

You will probably notice no difference in ride, braking or handling of your vehicle, but there are benefits to using nitrogen over compressed air.  With nitrogen filled tires, less air can escape your tires, your tire pressure will remain more constant as the temperature fluctuates, and there will be less moisture inside your tires, resulting in less corrosion on your wheels.Another benefit to nitrogen is that it is “dry air.”  Humidity or water vapor is not a good thing to have inside a tire.  Water present inside the tire, either as a vapor or in liquid form, will cause a greater drop in pressure, when the temperature changes, than dry air does.  Water inside the tire will also promote corrosion of the steel or aluminum rim.  When adding compressed air, water can be introduced into the tire from the air hose.  Any system that delivers pure nitrogen is also going to deliver “dry” nitrogen.  Filling tires with nitrogen involves filling and purging several times in succession, serially diluting the concentration of oxygen in the tire.  This will also remove any water.  Removing the water is a tremendous benefit to the tire.
