Is it because there is less or no PSI increase between hot & cold PSI?
Are the PSI's the same when inflating?
Any idea what they charge to inflate / tire?

 

Nitrogen seeps out of the tire a bit less than compressed air . It also runs cooler . As far as I am concerned ... A bit of a scam though . Tires still need to be checked regularly . Just because they " fill " with nitrogen , they are not maintenance free . I also have doubts about the nitrogen content at many places . I have a local tire shop that was scamming buyers .

 

When cars came out with TPMS, there were a lot of problems every time the weather turned cold... false alerts.

Dealers started putting nitrogen in tires to eliminate the false alarms.

Now they charge you for that.

Check your tires when you rotate and you will eliminate the need.

 

Only three reasons for nitrogen inflation:

1. You have a race car.

2. You have too much money.

3. You believe the marketing hype. 'Cause that's all it is. There is absolutely no benefit unless you refuse to check and properly maintain your tire pressures. If that's the case your tires will go flat a *little* bit slower.

 

Nitrogen is right there with K&N air filters......useless

 

When people ask me what I use I tell them I use a equally high performance mixture of 75% nitrogen, 21% oxygen, and 4% misc additives.
After the dumb look I tell them I use compressed air.

 

There is one fairly indisputable benefit to using bottled nitrogen vs most air compressors. That nitrogen is bone dry, and compressed air is not.

How much of a difference that makes is a matter of personal opinion.

 

That is a good point, particularly if you run balancing sand. I've seen it clump up with nasty shop air.
But with rudimentary compressor maintence you'll be fine.

 

There are many reasons not to use nitrogen. The cost and the availability are the 2 biggest. If you keep your tires longer nitrogen can lead to dry rotting faster because it doesn't hold moisture. Air actually forces moisture through the treads of the tire which MAY help keep the rubber from drying out.

 

I agree that nitrogen is not necessary for normal driving unless you do track racing.

 

Mine is. *Have moisture traps and filters installed on the supply lines as well as a few feet from the end of the hose(s).

A bottle of nitrogen is cheap, I have one strapped into my tool box, it's alot more stable than air, depending on were your filling your tires. Some shop compressor's have auto oilers, you dont want that in your tires, some shops dont maintain there compressors and are filled with water, and you dont have to worry about going out on a freezing morning to low tires. I use it for everything, I have a blow gun attachment, it runs air tools. I can fill all 4 of my 35" tires after airing down to run on the beach. I dont know what I would do without it now.

 

Interesting. I did not know that. I also agree with the guy above who uses regular air, which is mainly 3/4's nitrogen anyway. I believe that the yuppies and/or those who neglect a vehicle the most benefit from nitrogen. They think that because they get their ride oil changed once a year, or so, and the tires are checked, then, that everything is good to go. I personally wouldn't do it unless it were the same cost as regular air, and I am **** about tire pressure. I check with a quality gauge at least once every 4 - 6 weeks.

 

Of course you do Joe...and I bet you also have the compressor manual attached for quick reference too...lol

 

well I herd its cuz nitrogen atoms are bigger and it makes them harder to sneek out like big fat santa clause trying to fit down your chimney
I only use free air ,cuz if it wants to sneek out I ant lost nothing $$$
