I bought tires from Costco about 1 1/2 month ago for my Toyota Corolla. I went to get an oil change today and they said that the tires have nitrogen in them and not air. I have to get the nitrogen refilled each month at Costco only if I want to check my air pressure in my tires.
They added air to the tires for now since the nitrogen was low. Now I can go to Costco and get the air drained and nitrogen added.
The tires are BFGoodrich and mid-range. Has anyone ever heard of nitrogen being put in tires instead of air?

Nitrogen is starting to become more common. Air in your tires is responsive to temperature changes. It contracts when the weather is cold, resulting in your tire pressure going down. When the weather is hot, or when you drive and the tires heat up, the pressure goes up. Nitrogen does not have as much of a tendency to change pressure as air and is supposed to be more resistant to leaking. This results in the tire pressure being more consistent. Places that use nitrogen claim that is lengthens the life of the tire and increases gas mileage. It usually costs a couple of dollars to fill each tire. If the tire is filled with nitrogen it will have a green valve cap on it. This is common at Costco. You should not have to refill your tires every month. If they are getting low that frequently it is possible that you have a leak. Hope this helps.

Thats actually really interesting, I had no idea. I just bought some MIchellan tires for my Lexus about 2 months ago from Costco. They never said anything about filling with Nitrogen, but thanks for the heads up.

Yes it is getting more common to have nitrogen put in you tires for supposed increased fuel economy, however I guarantee you this was not done for free with your tire purchase because it is very expensive to do this. You better check your bill because if this was really done trust me you paid for it.
