I know this is a rather controversial issue. I was skeptical as well before doing this on my car, and I have not refilled my car tires for several months. Before that I needed to adjust the pressure every couple of months at least. 

Now I think it is a good idea to try this for our bikes. Especially since, when I see I need to fill up my bike tires, I get too lazy and give up the ride altogether. 

Is there a way to do this at home?

EDIT:
I thought I'd update the question for people who come and read later:  

Thanks for all the comments, I drive a lot (30kmiles/year) and I saw (to my surprise) a significant difference with nitrogen. 

I understand the reasoning with losing oxygen over time and increasing the N2 concentration but in practice that does not happen fast enough.  

I think I'll look into Helium/Argon and I'll update you if I managed to do something interesting. 

And I live in a small place I don't like to have a large pump but that is exactly why pumping is such a chore for me,


Question: Should I include high school details in Grad School Resume?
Answer: Ordinarily the answer is no, because it is no longer relevant to your aptitude for college, let alone graduate studies.

But if you won some national (or even local) science fair award for research in your current (or a related field), that would be relevant.
