do you fill you tires with nitrogen?

[car_crazy]

i keep hearing about people putting nitrogen in their car and how its a million times better than regular air that you get at the gas station. i was wondering is it worth the $20/avg that shops charge to fill up your tires?

Here's a pretty informative article about the truths and myths about putting nitrogen in your tires. Any questions you have should be answered in the article.

Thanks for the article. I was really debating doing this to my car but you just help me save $20. Its not a lot but still thats $20 I can put towards something else. I'd just rather regularly check my tires pressure and refill it for free.

Yea... nitrogen itself is snake oil. If someone in your mechanic's shop took proper care of the compressed air system, the air (which is 78% nitrogen anyway) would be dry... which is where the real benefit comes from.

Now, shops that have paid out $5K for a nitrogen filling machine have to make that money back.

I still have only ever filled my tires with air from the gas station pump. I mean I put gas in the car not rocket fuel... not sure what you really would see an improvment on.
