GM's take on nitrogen:
Nitrogen inflation can provide some benefit by reducing gas migration (pressure loss) at the molecular level through the tire structure. NHTSA (National Highway Traffic Safety Administration) has stated that the inflation pressure loss of tires can be up to 5% a month. Nitrogen molecules are larger than oxygen molecules and, therefore, are less prone to "seeping" through the tire casing. The actual obtainable benefits of nitrogen vary, based on the physical construction and the materials used in the manufacturing of the tire being inflated.

Another potential benefit of nitrogen is the reduced oxidation of tire components. Research has demonstrated that oxygen consumed in the oxidation process of the tire primarily comes from the inflation media. Therefore, it is reasonable to assume that oxidation of tire components can be reduced if the tire is inflated with pure nitrogen. However, only very small amounts of oxygen are required to begin the normal oxidation process. Even slight contamination of the tire inflation gas with compressed atmospheric air during normal inflation pressure maintenance, may negate the benefits of using nitrogen.

Also, nost places generate nitrogen with machines, this is not pure nitrogen, may only be 95% depending on the equipment and maintenance.
Better off using your money for a good tire guage

Talk about an RV soaring to 30000 feet...It would take a tow truck just to get mine to 7-8000 feet. I saw somethig in the morning paper about maybe using helium in the tires to make the vehicle lighter and therefore more fuel efficient.

Thanks to all who responded to my original post. Here is what else I have been able to find out.

I have talked to my neighbor who is a tire distributor and he said that the fuel economy would not be greatly improved if any at all but it would keep the tires cooler when running in hot weather and with a heavy load.

Most of the discussion is around car tires versus nitrogen. Fact is, we have truck tires on our motorhomes and run three times the pressure of car tires.

The fuel saving comes from keeping the pressure at the optimum level.

The biggest benefit of nitrogen though is life of your truck tires. Read the research for yourself:
