Nitrogen vs Air ??

[FLYTYER]

I just read where nitrogen gas as a tire inflation instead of air will provide about a 1.5 mpg boost in mileage. The nitrogen gas is available at numerous tire service facilities and gas stations are charging $6.00 per tire !!

Hmmmmm....can we use helium and lift the weight of our motorhomes off the road enough to float ??? This may give a better mileage boost.

In the first palce air is mostly nitrogen. I wold love to a written reason for why you need pure nitrogen in a tire to get beter gas mileage?

...I've read lots of unbelievable claims about nitrogen use in tires. The mileage claim is partly based on their claim that it will leak less, and therefore you are less likely to have underinflated tires because the average owner rarely checks their tire pressure. I don't know about it leaking less, but I check my tire pressures frequently anyway. Very limited research or even common sense show most if not all of the nitrogen in tires claims to be pretty weak or downright phony. 100psi is 100psi, no matter what provides it (well, water might be another story due to the weight.) I'll just stick with the nearly 80% Nitrogen I get for free from an air compressor.

Now, I think your suggestion about helium is much more promising! We need to check that one out a little further!!

[NeilV]

What I have read is that since it should leak out more slowly and most people don't check their tire pressures often enough that Nitrogen will help those people. Since it has smaller molecules Helium would leak out more quickly so it would not be as beneficial. The question does come up however that if air is 80% Nitrogen and Nitrogen molecules are larger than the molecules of the tire casings and the Oxegen etc molecules are smaller then - When you loose pressure in a tire shouldn't you have higher concentrations of Nitrogen and eventually have pretty close to pure Nitrogen in the tires anyway? Are we just getting there faster by initially filling our tires with Nitrogen?

NeilV, that sounds logical to me!!! I reckon since I haven't filled my tires in the past 4 months, most of the teeny oxygen atoms have escaped from the tires by now... -So I'm likely running all-nitrogen in there!

I just read that same article....increase your fuel mileage by 1.5 mpg



I just love newspaper fillers, probably written by the manufactures who make the nitrogen generators

Not true.

Actually Nitrogen Molecules are Larger than Oxygen Molecules.

All the hipe seems to be so that we will be paying $6.00 just to get our tires filled. Pretty soon they will be giving us free tires. the charge will be mounting, balancing, filling with nitrogen and cleaning them. That should raise the price enough to get the tire places rich.

That is what we have been saying all along.

Don't worry just an oops, we all make them every now and then.

Check out race car tires.
Nitrogen leaks less and keeps the tire cooler.
Less oxygen, less heat.
Nitrogen can also be use to get rid of water condensation in thermopane windows. It dispels water. Diamond drill a hole and spray it in.

Don't drill any holes in your windows. Dual or triple pane glass already has an inert gas between the layers - there's no oxygen at all in there. It's usually argon or krypton gas.

I'm going helium all the way- tires, suspension, and brakes. I wonder how many more miles per gallon that will bring me...

About as much as filling them with nitrogen. Somewhere between zero and none...
