Nitrogen in the tires?

Anyone know if nitro in our tire might help at all or if we can even do it? I know some people get it in their tires on their "cages" because it has less moisture than compressed air which in turn helps to keep the tire from expanding quite so much once the tires heat up and also gives a more accurate tire pressure.

Anyone ever tried this with bike tires or is Ride On sufficient enough?

Ride On is supposed to minimize air leaks. Not sure of any other benefits beside sealing punctures though. I'm wondering if the nitrogen is worth the money. If tire pressure is monitored regularly, as it should be, would seem the need for nitrogen would be moot. JMO

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Ride-on looks like good product. But, nitrogen, I found for each pro there were three cons= My opinion, don't waste your money on nitrogen.

I put Nitrogen in my tires at work (It is free for me) I did not notice any handiling improvement, it is just air. It is suposto help from expanding when getting hot and loss of air over time.
Personally I would not do it if I had to pay for it but we have it at the dealership so I did it.
It can't hurt.

If it were free or the same cost as regular air then I would jump on it. But it can't beat the free air machine at my local gas station.

Also, remember that our atmosphere is already 78% nitrogen to begin with. Is it worth the $10 a tire for an extra 22%?

Pure nitrogen is heavier and denser than air. Scuba divers sometimes fill their drysuits with nitrogen; being denser than air it's a better insulator.

However, we aren't diving. Since nitrogen is denser, it makes the wheels heavier, giving the bike slightly less performance.

Cons of filling tires with nitrogen:
Cost.
Heavier wheels.
Performance penalty.

Pros:
???


I wouldn't bother, it's up to you though.

Local dealer was having free nitro fills one Saturday so we all got it done. Notice no difference. Gives me another excuse not to check the actual tire pressure which is a bad thing.

Would never pay for it.

You are only partially correct in stating that nitrogen is denser than air. Air is made up of about 80% ntrogen and about 21% air. Nitrogen molecules are larger (denser) than oxygen, and they do not diffuse well through the rubber in your tires, so substituting pure nitrogen for air helps keep your tire pressure from getting lower over time. This will actually improve handling and provide better performance.

Pure nitrogen is not heavier or denser than compressed air because compressed air contains water vapor which is much heavier and denser than nitrogen, oxygen or the other trace elements in air such as carbon dioxide. Pure nitrogen contains no oxygen to oxidize (rust out) your rims and ruin your tires from the inside.

is it worth the price, probably not. Not to mention the difficulty in adding some nitrogen later on if your tires do loose some pressure. (Every time you check your tire pressure you loose a bit of pressure in the tire). You can't pull into a gas station and fill up with nitrogen, and you can't pump up your tire with nitrogen at home.

I fill my tires with Xeon and Krypton. They don't do anything better than plain air, but they sound cool.

If you buy a tank of Nitrogen you can fill your tires at home. The real problem here is even if you let all the air out of your tire and then fill it with nitrogen, it still won't be 100 percent Nitrogen as there will be residual air left in the tire.

You would have to purge the tire several times in hopes of removing all oxygen and water vapor before you saw any benifits of using the nitrogen.

I do not think that a tire filled with pure nitrogen would weigh significantly more than one filled with air, so citing "Added weight" as a con is silly.

Bottom line is if you can get it for free, it ain't going to hurt. But if you pay for it , you are just wasting your money.

Nitrogen does not seal punctures, Ride On does. They are two different things..but it does bring up the question if Ride On in a tire that is filled with nitrogen acts exactly the same as it does in one filled with regular air. ?

Just a thought. Figure I'll just go with the Ride On since it does seal punctures, helps balance the tires, helps keep the tires cooler and helps slow down the natural loss of air pressure.

About the only thing Nitro would be good for is help get the tires cooler and more accurate pressure than air.
