Dealer filled tires with Nitrogen. Can I add regular air to increase the pressure a couple of pounds to my liking without issue?

I'm probably leaving myself wide open here, but isn't filling your tires with nitro just a gimmick?

Its more stable than air. Doesnt fluctuate pressure as much

I think Tire Rack says it best.
"So what should drivers do?

Overall, inflating tires with nitrogen won't hurt them and may provide some minimal benefits.

Is it worth it? If you go someplace that provides free nitrogen with new tires, why not? Additionally we?ve seen some service providers offering reasonable prices of about $5 per tire (including periodic adjustments for the life of the tire) to a less reasonable $10 per tire (with additional costs for subsequent pressure adjustments) or more as part of a service contract, which we believe exceeds the value of nitrogen?s benefit.

Rather than pay extra for nitrogen, most drivers would be better off buying an accurate tire pressure gauge and checking and adjusting their tire pressures regularly."

If they do it free of charge why not but I wouldn't pay for it. I just check them with a digital gauge and adjust accordingly every 2 weeks.

Unless they used a vacuum pump to extract all the air, then it is already an air/nitro mix....................oh and air is 70% nitrogen anyway!

For general road use, it is sadly, mostly gimmick, the benefits are minuscule.

Yes, Costco does it for free. I got 4 brand new tires for my van last November. Drove to Colorado in the winter (froze my ass off, drove up to nocal during the summer and now it's a year later. Througout the past year the tire pressure looked exactly how it did since I got them.

Costco provide the nitrogen as part of their tire installation and I stop by their service bay to get it topped off when needed for free.

Benefits from nitrogen filled tires is minimal. Here's the analysis by Consumer Reports.
