Famous People Use Nitrogen Too

Even television celebrities like Jay Leno use nitrogen in their tires.

Inflating Tires With Nitrogen

Riding on Nitrogen

Properly inflated tires can save on gas. Nitrogen may be a way to save on even more gas.

Nitrogen in your tires can provide some benefits. Nitrogen does not leak out of your tires as fast as oxygen, so filling tires with pure nitrogen can help pressure retention. This means if you forget to check your tire pressure regularly you are less likely to drive on underinflated tires. And with the busy schedules of today, most people have trouble regularly checking their tire pressure. Of course regular air is 78% nitrogen already, so you cannot expect gigantic changes. Only the 22% that is not nitrogen is leaking out faster.

The second advantage of nitrogen is that it is less temperature sensitive than pure air. The temperature will be lower when you first start driving than after some road time. That means at the start of your trip you will be effectively driving on underinflated tires. That costs gas and increases tire wear. Pure nitrogen tires will suffer less from this effect, reducing the cold start underinflation penalty.



The video explains how an American picture frame manufacturing company is encouraging their employees to fill their vehicle tires with pure nitrogen. It also talks about the benefits of using pure nitrogen. Aside from the gas mileage aspects of nitrogen, the video shows how far back Detroit has fallen. When the nation has to count on picture frame manufacturers to promote fuel economy measures what does that say about Detroit's ability to survive in the future?

NItrogen in Your Tires

The picture shows liquid nitrogen being poured ... that super cold stuff you see in science demos. Air is about 80% nitrogen. Why would you want it in your tires, and how would you get it in there?

Both nitrogen and oxygen as found in the atmosphere form biatomic molecules. However nitrogen molecules are larger than oxygen molecules. The idea is this causes nitrogen to leak more slowly meaning you can go longer between tire refills without problems. Also because natural air has water in it and pure nitrogen does not, the nitrogen filled tires are effected less by heat. Finally, the oxygen in air can over time degrade the tires.

It is possible to find tire shops that offer pure nitrogen fills if you just look. To read more about nitrogen in your tires, follow the link!
