OK, all you big time racers out there, what is the correct procedure to purge air out of a tire before filling it with nitrogen?
The reason I ask is that any moisture mixed with nitrogen will create nitric acid, or some such vile stuff, if I remember correctly. What about using air tools? Looks like a job for rubber gloves. |

The first reason nitrogen is used is that it is the cheapest gas you can get in large quantities to take to the track.
Next, once processed, it contains little to no moisture. Moisture is a bad thing in extreme temp - freezes when cold (bad in airplane tires at altitude) and creates vapor when hot (raises the tire pressure much more than the ideal gas PV=nRT). Also, if a tire explodes, regular air has a higher oxygen content that will support combustion if ignited. There is nothing magic or particularly special about using nitrogen in tires - it just has a couple nice benefits at relatively low cost. |
