There is the Nitrogen tire inflating service in the big gas station nowadays.
The Nitrogen tire inflating service costs 50 baht for a tire. Is it worth and how is it necessary? Let’s find the answer together that inflating the tire with Nitrogen is better than the normal inflating, or not and what is the reason.
Do you know what is Nitrogen.
Nitrogen is one of the element in the periodic table, the symbol is N and the number of atom is 7, the status is gas and be 78% in the air
From the scientific information, you already got 78% of Nitrogen by the normal process.
If you use the Nitrogen tire inflation machine in the gas station, you will get 95% of Nitrogen, the Nitrogen purifier at 96-99.99% it will cost more than 100 thousand baht and at 99%+ will be used in the racing or the plane’s wheel.
How good the Nitrogen is.
Nitrogen is the pure gas without other substances, causing them to always maintain the gas status and slightly change the temperature. When driving, the heat will increase but the pressure still be the same level, make it difficult to burst.
But if it is the normal air, the pressure will increase about 3-10 psi. For example, if you inflated the tire about 30 psi (the standard for car), after driving for the long trip and measure the pressure by the digital device, it will show that the pressure increased about 33-36 psi.
This is the reason why we should decrease the air-pressure when having a long trip and only inflate the tire when it is cool.
Need to use the nitrogen, what must be done?
You must suck the air out of the tire not just release the air. It will be cost you and have to do by the correct process. But most people just release the air and then fill the nitrogen into the tire or change the new tire and fill the nitrogen into it. The quantity of nitrogen will be only 90%.
Fill in the nitrogen will make the tire slowly flat.
This information was mentioned in Consumer Reports, they testing many versions of tire by inflating some tire with nitrogen and the other with normal air, using the standard pressure at 30 psi. The average result after 1 year testing, the air inflated tire lost the pressure at 3.5 psi but the nitrogen infaled tire lost the pressure at 2.2 psi. The odd is only 1.3 psi.
Inflating the tire with nitrogen saves the fuel?
It is 100% false because saving the fuel depends on the air-pressure that lower than the EPA standard (U.S. Environment Protection Agency), already tested that the average car will waste the fuel about 0.3% at every 1 psi for four wheels.
For that reason, inflating the tire with air or nitrogen has nothing to do with it. Just check the air-pressure regularly.
The experience from the author who always inflate the tire with nitrogen.
It started after I changed the tire in the famous shop which offer the good price. Apart from that, the shop will inflate the tire with nitrogen for the whole age of tire if you changed the tire at the shop. The overall were just as same as the mentioned-information. The tire was not flatting slower or saving fuel and must re-inflating the tire with nitrogen at the same shop too. Now. I chose to inflate the tire with air which easier to acquire.
The conclusion for using nitrogen.
The problem is our tire didn’t get pure nitrogen which provide the completely difference, while the expense was high as 50 baht for a wheel. But for the collection car, contesting car or rarely used car could inflate the tire with nitrogen because these kinds of car usually get the pressure at the same position for a long time, making the tire worn out faster. The nitrogen would be the good choice for maintaining these cars.
