Well, actually the work of the compressor pumping the air heats it up and the air actually comes out of the compressor with more moisture content. That is why at our body shop we have to have a huge 3 stage oil and water filter on the air lines before they go in the booth and oil/water traps on the lines into the air tools.
The comment about Nitrogen being a inert gas is correct, it does not breakdown the rubber compounds in the tire. However it is more expensive (due to the cost of the machine), and of course you have normal air on the outside of the tire, so lowering the oxidation on the inside of the tire is only half the battle really. The tire store I deal with has a nitrogen system but they told me privately its just a upsale device really. On that Mercedes, I bet the sensors were probably calibrated for Nitrogen.

It's probably pretty dry coming out of a compressor anyway. I also can't see the advantage of putting an inert gas in the tires. You still have air on the outside of the tires. Seems like a waste of money. Tom Tomlinson '71 Malibu [email protected] wrote: Another question about nitrogen. Shell claims their gas keeps your engine cleaner. Having worked in a chemical plant and refinery's and knowing that nitrogen is an inert gas and doesn't burn, how then can it keep engines cleaner. Nitrogen is used to purge other gases in welding and vessels. Just wondering , can anyone answer my thoughts. Wish I was still working and could ask the engineers.

The folks who buy them need a return on investment, so they tout the benefits of nitrogen so they can sell it to you. To my knowledge, there is no research that shows any thing that makes it worth the money that the consumer spends. It's a profit center (once the machine is paid off) for the business that buys the equipment, nothing more. Racing teams use nitrogen to fill the tires so that they can have a consistent rise in temperature and pressure because of the lack of moisture in the tire. Street tires don't need it.

The claim is that nitrogen is better than compressed air in a tire. They claim that nitrogen is a dry gas and is free of moisture. It doesn't deteriorate the rubber and it is lss susceptible to air loss with temperature changes. I'd be interested to hear what the "group" thinks about this.
