Nitrogen in the tires?
Ok it seems like every time there is a gas crisis I hear the fill your tires with nitrogen commercials.
Bottom line, does it really improve your MPGs, and I'm talking more than 1 or 2 extra.
The way I look at it is the O in the tires doesn't weigh enough compared to N, so i don't see a MPG increase because the car is lighter.
I'm pretty sure N is a lighter element than O, so would N have a tendency to leak faster than O? I'm not saying you'll have a flat in two hours or even two weeks, but wouldn't you still loose N over time just like you loose O over time?
I just have to ask, because I get tired of hearing about people getting an MPG increase just because they roll with N vs O.
I mean 2-3 MPGs is like a 10% increase on most cars. I can't even get that kind of increase even if I baby it and drive 60 on the highway.
thanks

well i dont know about the weight but i do beleive that the nitrogen does not expand and contract as much as oxygen does in the tires.

i could agree with that, but are tires designed to hold that gas? I'm looking to compare the idea of O escaping the tire vs can N escape (even if at a slower rate?
so is that the trick behind better MPGs the fact your tires stay at the same PSI for longer?

nitrogen will not seep through the tiny holes in the tire compound like o will plus it will not deteriorate your tires like o will because it doesnt build up condensation inside the tire when they cool down like o does i worked at a tire manufacturing company and retread company leaned this from the old timers there also n doesnt expand like o will at high speeds thats just the info i recieved hope it helps
