OK, this is pretty off topic for what I usually write about, but lately I've been hearing a lot of commercials for tire places that offer nitrogen inflation. Being the natural skeptic that I am, my first reaction was to say, "What kind of bullshit scam is this?"
Last night I looked into it and there appears to be something to it. Inflating your tires with nitrogen causes the tire to run 20% cooler than regular air giving you up to 26% more life on your tires, and the inflation generally runs around $5 a tire. Would have never guessed it.
