Nitrogen Tire Inflation
My car came with NitroFill when I bought it.
Any one has experience? How much does it cost?
Time for my tire replacement soon and considering Nitrofill if the price is right.
Any suggestions?

I'm sticking with regular air, which is 78% nitrogen, and free. I could see using 100% nitrogen in critical applications, but driving on the street isn't one of them.

The nitrogen that is installed in tires is not 100% pure. As already stated, the air we breath is made up of 78% nitrogen. The nitrogen for tires is not worth paying any extra for at all.

Nitrogen molecules are much larger than those of most of the components of the air we breath so it leaches out of the tire at a slower rate than air which means the tire pressure will be more stable over time. Also the more nitrogen in the mix the less water can be held that may damage the wheels over time. Problem is we are not going to go to the dealer every time we need to check the pressure so over time the mixture will have less and less nitrogen. So, if you are not concerned about those things then it's really not needed.

I'm with others, I'd do it if it's free and convenient. It's usually more convenient for me to check pressure at home and add air if needed to get a proper cold fill.
I've heard people claim a tire may lose 1 PSI/month due to bleed-off, my experience has been that it depends on the tire, installation, and roundness of the wheel. I've had tires that lost 5psi/month and tires that maintained constant PSI for 9 months straight. All air-filled.

I asked for this when I first bought my '13, and the salesman literally told me, "We used to offer nitrogen but then decided it wasn't worth the trouble and almost nobody asked for it anyway, so they pulled the machines for it and went back to air". Good enough for me, if a huge dealership doesn't think it's necessary... Either that or they weren't able to upsell it.

I just go to Costco and fill my tires for free, if they ask I just tell them I bought the tires from them (when I didn't), thats the only way I'll ever fill my tires with Nitrogen.

All tires have microscopic pores through which any inflating gas, air and nitrogen included, will seep out over an extended period of time, gradually lowering the inflation pressure. Nitrogen has larger molecules than air and will move through the tire more slowly than air, thus maintaining the inflation pressure longer.
Consumer Reports conducted a study comparing nitrogen versus air loss in tires to determine if this benefit of nitrogen was worth the extra cost. They used 31 pairs of various tire models, filled one tire of each pair to 30 psi with air and the other to the same pressure with nitrogen, then left them outside for a year. At the end of the year, they found that all tires lost pressure. The average pressure loss with air was 3.5 psi; with nitrogen the average loss was 2.2 psi – a difference of only 1.3 psi over a year.
Just one of the many problems with using nitrogen to inflate tires is that you will not find 100% pure nitrogen at any place that carries nitrogen for tires. Filling tires with less than 100% pure nitrogen can actually cause perplexing problems over purely air filled tires. But, that's just the half of it. Watch the two videos for the real truth...especially the 2nd video for the no-BS truth.
