Tire pressure

[JAS POWER]

Don't waste your time or money (if thats the case)...

I tried it in a car, thought it would be great because here in Wisconsin temps always go up and down. As soon as the temperature drop the stupid light came on the dash stating low tire pressure or a flat. Then I had to go back to the tire store to have them top it off, when I could have used my own air out of my compressor in my garage. I eventually got so sick of it I just started adding my own air from home. So I will NEVER use nitrogen again!

I FEEL ITS A BIG SCAM :dontknow:

Just joking

Just like with my GMAW welding gas I use a special mix of gases for my tires. With some slight variations it is custom blend of 78% Nitrogen, 20 to 21 % Oxygen, and 1+% other gases. It seems to work well and the cost is only to compress it.:joke::joke::joke:

100% nitrogen not needed for normal folks.

I may be mistaken, but I think you have just described air.

The reason NASCAR uses nitrogen is because it is more volume stable as the tire heats up from use. You would not notice this difference in your passenger car tires.

If you are anal about the pressure you would.
The difference (mostly) is the absence of water vapor in the pure nitrogen.
Water vapor changes pressure quicker than the other gasses alone.

aluminum doesn't rust, it corrodes. the moisture will rust chrome plated aluminum rims and can cause galvanic fusing of the valve
core and a valve pin.

"Moisture" does not cause corroding; oxygen does.......or caustic impurities mixed in with the water.

Joking, Joking, Joking

Hi Ben,

The Little symbol :joke::joke::joke: Means or ='s I'm joking. So of course I am joking about the " special" gas mixture I use. I know that sarcasm is the lowest form of humor but I learned it from the best.

So please don't take my answer as a personal attack. ( LIKE TO MANY OTHERS ON THIS SITE DO )

I am a tire specialist for a NASCAR K&N West team. We purge our tires with nitrogen in an effort to eliminate moisture. Moisture in the air causes an increase in pressure build as the tire gets hot. On our practice tires I fill with nitrogen then allow it to almost completely drain out then fill again. On our race tires I do this 2 to 3 more times depending on the humidity at the track. A purged tire on the right will build approximately 10 pounds from cold to hot with hot being considerably more than a passenger tire as most of the heat comes from the brakes.

As said by other members if the tire is not purged of moisture there is little benefit for even a race team. Even in racing, the need to run nitrogen in my opinion depends a lot on the humidity of the air. There is a difference in pressure build in a high humidity costal area verses the desert of Arizona. As a traveling team consistency between tracks/locations is very important. Also, the cost of nitrogen is a very small part of the racing budget.

I have raced at the local level where the local track is low humidity. We have been very successful using air from a compressor and monitoring the pressure build so that we know where to start cold. Size of the tire makes a difference as well. While some do, we do not run nitrogen in our racing karts. The tires are small and because the brakes are inboard the temperature/pressure build is small as well. My 12 year old driver has won 4 local championships in 5 years and a regional Gold Cup championship all on compressor air.

As a side note, drain the moisture from your compressor regularly.

Has anyone tried using nitrogen in their tires to control expansion from heat?

there is lots of good info out there on this nitro scam......in short its all BS. nojoke
