Does anyone with nitrogen filled tires... done by a shop... KNOW, without a doubt, that they have 100% nitrogen in them?
What a great way to make money. Offer, for an additional cost, nitrogen fill. Then you can put anything you like in there because 99.9% of the population has no way to test if there is nitrogen in the tire or just air. Just another placebo effect I'm certain. You believe you have nitrogen in your tires, thus begin to experience the alleged benefits.
Where I got our tires at has a nitrogen filling station that has a high pressure nitrogen tank sitting in it with a regulator and the hose with the air chuck attached to it. Other places I have gotten tires and/or a flat patched from the inside of the tire - I cannot say.
