Good Reasons To Use Nitrogen

Advertisement

Editor:

In response to Al Buckner and his letter on nitrogen. Yes Al, you will probably get along just fine on your tires filled with good old air just so long as you don’t run them over five years and you keep the pressure “topped off.” And, as you know, topping off is a regular maintenance item for tires filled with the normal nitrogen/oxygen mix.

However, sometimes that “topping off” gets overlooked resulting in tires running with low air pressure. You see the end result every day with parts of tires spread all along the highway. Yes, air is 80 percent nitrogen and 20 percent oxygen and it is the oxygen that leaks out. Get that $29 nitrogen fill for all five tires and the next time you go to “top off” you will find that your tire pressure has not declined. Cheap insurance for you and your family.

And then, ask yourself, why do so many new cars come with nitrogen fill? Why does NASCAR use nitrogen? Why are airplanes required to use nitrogen? Why are some of the largest tire distributors in the U.S. using only nitrogen? There are many good reasons and many good answers.

Look closely. Those are not passenger tires, but heavy truck tires. Recapped tires are common on heavy trucks, but I've never known 18 wheelers to run nitrogen in THEIR tires. Have you?

Where did this "five year" rule come from? Not from anything I've ever read. After five years, do your "regular air-filled" tires self-destruct? : ) Mine never have.

I have read that nitrogen filled tires will not increase their air pressures as much as regular air. When you're racing in circles at 180 mph on hot surfaces, that could be beneficial. NASCAR racers will spend massive amounts of money to get the most tiny advantage over their competition. Cost is no object, to them.

One thing is certain. Paying a tire shop to put 20% more nitrogen in the tires of your daily driver is a really great way to waste your money.
