Nitrogen in tires?

So just check your tire pressure often and you'll save a lot of money on nitrogen fills. If you check your tires like you should, you'd need a bottle at your house or you'd spend a lot of time at tire places paying them to do it.

My tire place put nitrogen in my Toyo's when I had my tires replaced a few years back. I would have never asked for it, but I have noticed that even after two years and 30,000 miles, I have only had to top off the pressures once or twice to maintain spec. Also, the tire shop that installed the tires offers free checks and top ups, so there was no extra cost.

As you said, performance benefits on the street are nill, but I do see how it could be a slight safety benefit to someone who doesn't check their air pressure as much as they should. Especially an SUV.
