I just had the tires on my HCH II filled with Nitrogen. It is supposed to give improved tire life, safety and increased fuel economy. I just got the vehicle this past weekend so I won't be able to really see if I get improved fuel economy.

Has any one had any experience with Nitrogen filled tires? Has it increased your mpg's?

If you want more info, you can check out their website at

They also checked the tires and said they could be inflated to 44psi. Is this a good idea to help increase fuel economy?

Thanks in advance for your insight....
