where do you get pure nitrogen to fill up your tires? Does discount tire offer it or something?

 

Alright, that's it. I'm going to have to out-inert everyone and go with an argon-krypton-xenon combo for my tires. Nitrogen just won't cut it with me. Maybe they'll start glowing when I do burnouts.

 

Some (if not all) Costco locations that have tire centers offer nitrogen.

 

I have done some research etc and this is my conclusion...

The use of nitrogen has a lot of benefits. It is an inert gas which means it will not react or corrode the wheels or tires.

The fact that it maintains a steady pressure is beneficial as well, both on and off the track. Just using my tpms in the morning when its cold, and watching how much the air in my tires increases is pretty amazing. I could start off at like 34-35 and end up at 38psi+ at times. In theory there should not be such a huge change in pressure due to expansion of air/heat.

Nitrogen also does not escape the tire as fast as air does, meaning the average joe or joette who never checks their tire pressure will most likely still be at a good psi i leve after months of driving and neglect. Just at work when I walk around i can spot lots of tires that are probably running in the 20s that the driver doesnt notice or probably doesnt take the time to check.


I personally have not used nitrogen yet, but its mainly because they want to charge an arm and a leg. I would be willing to spend $2-3 per tire, but thats about it. I usually check my tire pressure once a month, so my tires are usually within spec.

There is good science behind using it. The reason a lot of places charge is not only to make a quick buck, but the equipment is not cheap. It is actually pretty expensive.

 

i look at it as being the lazy person's fix for not doing proper maintenance on your car. and a waste of money. if it is too much effort to check the tire pressure at least once a week, then you should not be driving a car IMO.
