What are the benefits of inflating your tires with nitrogen gas?

I've used nitrogen inflation in racing car tires for a long time. The advantage that I have personally observed is nitrogen has a more predictable change in pressure as temperature increases. This is because you do not have the unknown factor of the amount of moisture in the compressed air. This is important because you are looking for an optimal "hot" pressure and you start off the race with a "cold" tire. To contradict what someone else said, all gases change pressure as temperature changes. Nitrogen will not have a constant pressure over a temperature range, just be more predictable.

For road cars the only real advantage that I see is that you do not have any oxygen or water inside the tire. This might prolong the life of the internal structure of the tire by preventing corrosion, or it might not. I don't think it would make a difference over a few years. I do inflate my trailer tires with nitrogen, because I never use my trailers enough to wear the tread off the tire before they fail from tread separation, dry rot, or cords slipping.

For a couple hundred bucks or less you can have your very own nitrogen setup for refilling your tires.

Nitrogen is a totally dry inert gas. It is used to stabilize the pressure in your tires. Nitrogen atoms are larger than Oxygen atoms making it (N) more difficult to pass through the tire sidewalls. With a more constant tire pressure, the theory is that tire wear, handling, fuel economy, rolling resistance, etc. will be improved by not seeing your tires over or under inflated. I have heard that it costs about $10 to change the air to Nitrogen in four tires. I have heard that the effect of Nitrogen filled tires cannot be detected unless you are driving a lot of miles per year. RSVP

Just the latest fad gimmick.... some race cars use it in their tires because the pressure is more consisent than regular air. For the average motorist, not worth the money to have it done.

The nitrogen has larger molecules and it will keep the temperature and pressures more constant. This will help with mileage and tire wear. Good luck. Around here they want 7.50 a tire to fill it with nitrogen.

Nitrogen in tires is becoming a popular replacement for standard air. Nitrogen is all around us... the air we breathe is 78% nitrogen, 21% oxygen and the rest is small amounts of other gasses. When it comes to tire inflation, nitrogen has many advantages over oxygen. With nitrogen tire inflation, improvements can be noted in a vehicle's handling, fuel efficiency and tire life through better tire pressure retention, improved fuel economy and cooler running tire temperatures

None.. Test were performed on Big truck tires and the result was absolutley no temperature difference In the tires after 2000 miles of running one type of tire on the truck and trailer. One side filled with nitrogen and the other with pumped air. The rumor was that the Nitrogen would keep the tires running at a cooler temp. Helping the problem of Blow outs on tires from overheating.

trust your judgement,yes it is worthless.

thers only one benefit. nitrogen pressure dosent change with temperature as o2 dose
