my dad has it in his tires they are the same as mine Firestone destination a-t and he has no mpg gain and my tires are wearing the same as his so i dont see a benefit.
Nitrogen molecules are larger than air molecules, so they are less likely to leak. Nitrogen is also dryer. That means little to no moisture in the tire which makes a difference with TPMS vehicles. You will not see any noticeable mileage increases or decreases with either one.
Ken,
Tell 'em what you put in the 18 tires on your "other vehicle"?
With air being 80% nitrogen to start with you really have no advantage to using nitrogen other than being able to carry a high pressure cylinder 80cu/ft to fill up after airing down for dunes or operating impacts ect....
No, air is not "smaller" than nitrogen, unless you want to count the 1% Argon. What air is is wetter than nitrogen, 1-3% typical. If there is any bennefit, it is that nitrogen is dry.
CA is requiring Nitrogen? Why doesn't that suprise me? Wait until they figure out that we're running out of air because of all the tires.... That should be entertaining.
Nor would there be a need for Federally-mandated TPMS, either!

Agreed.
We're heading for a whole new level of stupidity in this country, with less freedom, more Government control, and I'm pretty sure I saw an Obituary for Common Sense a while back.
I'm glad I read this thread, it's made my decision for me.
If Calif. has passed a law requiring it....I will for sure stay the hell away from it period
Only in America
Actually, California has mandated that shops inflate the tires on cars they service to the door-sticker values, but it DOES NOT have to be inflated with nitrogen (GN2)!
