Sending tv reporters back to high school?
Channel 10 in Philadelphia (nbc10.com) had an interesting news report (in the context of tire inflation) at 11:20pm on Oct. 11, 2005 about how nitrogen was 4 times heavier than oxygen [Channel 10: "Nitrogen is four times heavier than oxygen, so those molecules are bigger and won't be able to escape through small leaks in your tires," said Catherine Rossi, of AAA MidAtlantic]. and about the moisture in oxygen [Channel 10: The moisture in oxygen not only expands and contracts, it can also prematurely corrode your tires.] The atomic weight of nitrogen is about 14 and of oxygen is about 16. Oxygen contains no moisture (water).
This is a bit worse than the district court Osram case (using atomic number, rather than atomic weight, to do stoichiometry), and certainly merits someone from junkscience.com taking note.
For posterity, here is the clip:
One small change in your driving habits can save you money and keep you and your family safer on the road.
NASCAR drivers and NASA have been using nitrogen in their tires for years. Now, you can use it in your tires for better gas mileage and safer handling.
"I've even had dealers call me up and ask me what's up with nitrogen, because a lot of them don't even know about it," said Thomas Taylor, a Costco Tire Center manager.
"Its the best thing for people who ignore their tires," said Kevin Rohlwing, of the Tire Industry Association.
That is why Costco Tire Centers across the country offer nitrogen over oxygen. The benefit is two-fold. Your tires stay inflated longer and because nitrogen is very dry you will see less pressure fluctuation than you get with oxygen.
"Nitrogen is four times heavier than oxygen, so those molecules are bigger and won't be able to escape through small leaks in your tires," said Catherine Rossi, of AAA MidAtlantic.
"If you put regular air in the tire, it's going to have moisture in the tire and as the tire heats up, that moisture vaporizes, turns to gas and it inflates the tire more," Taylor said.
The moisture in oxygen not only expands and contracts, it can also prematurely corrode your tires.
"We definitely feel that nitrogen is favorable to the tires. It is going to help them run cooler. It is going to help the pressure be more consistent and even," Rohlwing said.
Consistent pressure is key for safety and handling. Experts say that 600 fatal accidents each year are attributed to low tire pressure. The Energy Department says consistent tire pressure, whether it is nitrogen or oxygen can improve gas mileage by 3 percent.
However, the Tire Industry Association and AAA agree that nitrogen is not a substitute for an air gauge. You should check your tire pressure every month.
"Still check it, but you won't have to fill the tire as much as you would with regular air," Taylor said.
"If you are a person who puts a set of tires on your car and the next time you worry about them is when you get a flat, or you skid on snow or ice, then nitrogen is a good thing for you," Rohlwing said.
AAA said that the biggest problem with nitrogen right now is that because of the high cost of equipment, not many service stations offer it yet. Costco is offering the service to their members locally and across the country.
Remember, whether you use nitrogen or oxygen, the key is keeping your tires at the right pressure.
One out of four tires is significantly under inflated.
