Tire Fill

[03Silvy]

In the coming months I'm buying new rims and tires for summer (whats left of it) and new tires for winter for stock rims. Just wondering how many of you guys use nitrogen fill as opposed to air cause the place I'm going to will fill nitrogen for free. My problem, then I have to go back everytime my pressure fluxuates (which it shouldn't), but I like lowering the pressure in my tires in the winter for more traction and maxing them out in the summer for highway milage. Any opinions on nitrogen vs. air?

If you play with the pressure that much, I'd say just use air.

I'd use Helium, it will make your truck lighter and you'll get better mileage.

This might fall into the gimmick category since nitrogen still has air in it...still, if it's free, free is good!

Nitrogen has bigger molecules, so it doesn't leak out as much. Plus it's less prone to fluctuations in pressure to do expansion/contraction when hot or cold.

 

Or...I'm full of chit.

I understand the reasoning and possible benefits of using nitrogen. I thought the same thing and almost had it R&Red into my Corvette and Silverado tires...then I read some more information. It would seem like it's a great profit margin product for places that sell it.

 

Nitrogen is the largest single component of the Earth's atmosphere (78.082% by volume of dry air, 75.3% by weight in dry air).

 

That would still leave 22-25% air in the nitrogen if I understand this correctly. I wonder if it smells better than stale plain old air...

I'd go with acetylene

the biggest thing that most all truck owners forget to do is change from winter air to summer air.........took a couple years, but we finally got Ryanbab to understand this and now he changes from summer to winter air religiously.....you readin this Ryan?

 

took a while to make him understand what a muffler bearing was all about too.........

We only use nitrogen only in airplane tires (and shock struts). It expands and contracts less and it has no water in it. This is important due to the extreme temperature differences an airplane tire experiences in flight. But, nitrogen is readily available at airports so it's easy to keep airplane tires and landing gear struts to the proper pressure. For everyday use in a car/truck, it's a total waste of time to worry about nitrogen. Just use air from a good compressor with a water separator.

You took the words right out of my mouth! I thought I was going to get to be the smart one.
