In last Sunday’s newspaper I noticed an advertisement from one of our local Chevy dealers that was offering a half-price sale on nitrogen for your car tires. So I went out to see what I could find out about the benefits of running your tires filled with nitrogen instead of plain old air.

The Get Nitrogen Institute states the benefits as:

Proper tire pressure is a big deal.
Maintain it with nitrogen, and you’ll see
these three primary benefits:

  • Increased Fuel Efficiency – Correct tire pressure keeps the manufacturer’s recommended “contact patch” on the road. This lessens the rolling resistance and maximizes fuel efficiency. Read On
  • Longer Tire Life – When it comes in contact with other materials, oxygen causes oxidation. Oxidation can make rubber brittle and cause it to lose tensile strength. In addition, at high temperatures and pressures, oxygen reacts and damages inner tire liners and belt packages; nitrogen does not. Read On
  • Increased Safety – Under-inflated tires cause 90% of blowouts. Nitrogen provides more reliable pressure for reduced blowout potential. Read On

The local dealer’s half-price sale was $19.95 to fill your tires with nitrogen. I have not personally used nitrogen in my tires, so I haven’t a clue whether the savings are for real. If anyone has tried this, please share your thoughts.

Comments welcome.


PS When I mentioned this to my wife she said ‘now we have to pay to have our tires filled with gas?” 🙂
