Filling tires with Nitrogen?, Is it worth it, and how much is it about? Options

[I3arruka]

Well yeah, was in CostCo today and they had an advertisment saying "We take tire safety to the next level with....NITROGEN Tire Inflation!" I read the flyer everything seems lagit, question that comes to mind tho is it worth it? Is it actually better than filling you tire with air? How much should it be?

Thanks

Nitrogen is more compact than the regular "air" we use in our tires. The good side about nitrogen filled tires is that they will not expand as much.

EX. While autocrossing my tire pressure would rise up 3-4 PSI with regular air. Most of the time their unbalanced. With Nitrogen the most Ive ever seen my tire pressure go up is.. 1-2 PSI. The pressure all around stays more constant.

so in short, yes they have a minimal advantage over regular air.. but if you get it for free.. nothing wrong in using it.
