Nitrogen filled tire

What I learned is that plain air will leak right through a tire eventually. It's the molecules other than nitrogen that pass through. Nitrogen molecules are bigger, so they don't pass through the tire rubber. If you fill with "pure" nitrogen, you won't lose air over a long period of time. It's also more stable, does not expand as much with heat, that's why NASCAR teams use it. Some Costco's have nitrogen.

Or, you could just check your tire pressure more often.

You are correct sir! It's more stable because it's much dryer than regular air.
The reason NASCAR tires are inflated with nitrogen, rather than the normal air we pump into our tires, is due to the increased stability under hotter temperatures that the gas exhibits. It allows the tire pressure (Up to 50 pounds per square inch) to remain constant throughout the race regardless of the temperature, which can reach 200 degrees Fahrenheit. (from NASCAR's website)

 
I have only had experience with nitrogen in our motorhome tires. Month after month, cold or hot weather, the tire pressures remained the same...whether it had been driven or just sitting. It was initially housed in a climate controlled airplane hangar then moved to a storage shed that was open on one end and subject to all seasonal temperatures for several years. Nitrogen worked for us in that instance but have never put it in a car or motorcycle tires.
 
True Nitrogen is supposed to seal the tire better than straight air

I have had doubts about this for years and cannot see paying for what I can get for free JMO

Keeping in mind air is 78 percent Nitrogen:p

So why don't tires with air or go 78% flat if nitrogen won't go thru?:Shrug::Shrug::Shrug:
 
Nitrogen in the tires were A gimmick started by the Florida new car dealers Association many years ago this way they can convince all the old gullible retired people that they have to come back to the dealer and pay for nitrogen in their tires every time they Needed a top off of nitrogen ����

Another gimmick to separate dollars from your wallet to theirs. Tried it years ago,not worth the $$. Also the more you check the pressure the more of it you lose.

I agree with the above completely.

Back in the 1980's I experimented with and used nitrogen in my racing gokart tires.

I had a repair shop so bottled gas was easily obtained.

I took an old freon tank and used it for nitrogen filled to 90 psi and carried it with me to the races. Small sprintkart tires and small tracks with flat tight turns.

The air would expand 8-10 psi during a short 10 lap race making for a very slippery kart at the end of the race. Nitrogen didn't expand at all in those tires and I could adjust my race pressures and not have the bad handling characteristics of low pressure, not to mention the chain and sprocket eating the asphalt, until a desired heated air pressure was reached.

Never thought of using it other than in competition because of benefit over expense.

Using it for tires belongs at the racetrack and in aircraft ..... or maybe if you are going from the Florida Keys to Pike's Peak .......
:Joker3:

However, I do have a Nitrogen Factory and a bridge for sale in Brooklyn ..... CHEAP !!!!
 
Thanks for all the feed back. I'am just going to leave it in there till I have a flat. And I'am a retired pipe line welder so the nitrogen is no problem for me to aquire
 
Thank you Jim , well explained :clapping:

Every thing was fine till the idiot light era arrived!

The idiot era arrived when Power Steering' Power Brakes and Auto Transmissions became widely available, To the masses of idiot's who now think that they can drive...:D
 
I just changed a tire on a rim that had been mounted since 1999. Boy .... I never realized how much fresher the air is now compared to how that air smelled.:qpnmt:

That's funny Jim!

In a past life, I used to dismount tires at a local used car parts recycling yard where I worked. The first time I smelled the rankness coming out of a tire when it was deflating, made me gag.

After awhile I got used to it but it made me wonder, to this day, what made that smell since it was only "air" in them....:Shrug:

.........kinda like 'pass'n gas', when I only ate a burger........
 
Me too :) I also change the air and make sure I have the air for the correct season installed. Ie: Summer air, Winter air, etc

Still have winter air in. Spring is just around the corner,so shopping for a good deal on Spring air. Summer air is still on clearance ,so might stock up on some. :D

What happens when you over marinade in a rubber container.

It's the moisture in the air.

You're right. "Dryer" is the whole reason. Water in a tire at NASCAR and other racing temp's constantly shifts from liquid/vapor to steam which has more volume and thus raises tire pressure, often when you least want that. Imagine drifting a car at 200 mph with your tire traction constantly changing! Any *dry* gas avoids that. Nitrogen is simply cheap and readily available. You could use Oxygen but crashes would get real interesting. I'm surprised NASCAR hasn't mandated it as a crowd pleaser.

For normal street use? Waste of time and money. But its your time and money so ...:qpnmt:
