Author's Note: Will nitrogen-inflated tires save fuel?

This is my confession: I don't check the air pressure in my tires. Like, ever. I have written so many articles on mileage and tire pressure. I know all the stats and all the benefits and how cheap and easy it is. I even have a tire pressure gauge in my glove box -- should I decide to practice what I preach. I don't think I've ever used it. But the tire gauge came with a matching pen, and I use that. It's pretty much the same thing, I think.
