I bought a set of 4 new Nankang NS20s and the guy at the new local tore store told me he doesn't think I need nitrogen in them. I used to run nitrogen. I used to seem to have tires that needed be be topped off with air every 1-2 months and the nitrogen seemed to help seal the tires and lessen my need to top them off so often. These tires have been on for 6 or 7 weeks and I don't think I've lost one pound yet.

Thanks to this place I saved $100 on these tires and will spare myself of the $25 for nitrogen.
As long as they hold their pressure, I'm fine with dry compressed air.

Nitrogen is a $$ scam, IMO.

Cars tire have ran fine for literally 100 years without it. 99.5% continue to do so today.

FWIW, Air is 78% nitrogen.

You have 78% nitrogen now. smile.

Unless they pull a vacuum on the tires and fill with pure nitrogen then you will not have pure nitrogen in the tires.

No worries. Drive on.

Nitrogen is a big profit maker not much more and not worth it.

If all that pesky O2 is migrating out then your tires should contain more nitrogen by % very soon.

My work just got another nitrogen exchanger machine thing. We had one before and parts was stuck with keeping track of the green stem caps. I have no idea what service charges for it, but I swapped my Mustang over after work yesterday. I would say maybe up to $10 would be fair, but anything over that you have diminishing returns IMO.

As you add air a few times the oxygen will have slipped out since much smaller molecule.

As the tires age they should tighten up, and lose less air.

My Hankook V12's were so hard at 4 years they held 35 psi for 2 more years.....not even kidding.

Nitrogen is great for air craft and race cars and I wouldn't pay for nitrogen. Free put it in.

I don't know where the drive for 100% Nitrogen came from. Maybe an extra profit centre? Maybe a low cost way to have compressed gas on site without the bother of maintaining an air compressor?

Yes your wheels might be as much as a gram or two lighter and that would be important on say, the moon lander or the space shuttle (though hydrogen or helium would be even lighter).

All you really need is dry air. 78% Nitrogen is just fine. Drive on.

Free nitrogen at Costco, why not? Paying for it? No way.
