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!
