Do Nitrogen Filled Tires really make a Difference?
Write a Review
If you ask us which of the F1 or Car racing technique you can implement most easily, we will say “Nitro Tires”. Now what difference it will actually make in real if it comes to a nitro filled tire, both will inflate the tires right? No in fact there are couple of reasons why a person should prefer Nitrogen over normal air when it comes to his tires, though it can be a bit expensive at first but will work in your favor in a way. There are certain reasons why you should choose Nitro over Normal air.
- Nitrogen doesn’t migrate easily like air does.
Nitrogen is less likely to migrate through rubber tire, which means tire will hold its pressure for much longer without any noticeable drop in air volume contained inside, and we don’t need to tell you that a well inflated tire means a fuel efficient vehicle. In air filled tires you will lose 1.5psi in a month whereas it will take around 6months to lose 1.5 psi in case of Nitrogen filled tires.
- Nitrogen is inert.
As we all know nitrogen is an inert gas, chemically not truly but can be called as one. Therefore it doesn’t react with anything inside like normal air does, normal air includes 78% Nitrogen, 21%Oxygen and 1% other parts, and oxygen inside of it reacts inside and results in the oxidation which again resulted as Tire rot and Corrosion. Nitrogen should be 95% pure at least for which you must bleed out previously filled air.
- Nitrogen is free from Moisture.
Air filled inside tires usually contains a significant amount of moisture and water vapours as its constituents as most of the stations don’t keep moisture out of their systems. This moisture can result in frequent pressure changes, corrosion of steel and even water deposition in few cases. Reason being normal air already consists traces of water vapor in it, which usually get accumulated and condensed once get compressed inside a tire.
- Nitrogen exhibit less pressure change with temperature.
All Tires get hot under speedy rides for obvious reasons, and especially when we are dealing with F1 only nitrogen is our safe option as it does not expand much under a temperature rise. Also with regular drives, if you travel for long distances or you love to drive it fast you will definitely undergo a great psi change, that’s pressure. It means you are under a risk of a tire burst, more likely if your tire is old or bruised. For this same reason NASCAR and IndyCar teams use Nitrogen filled tires as it is easier and more accurate to predict pressure changes (psi) with nitrogen as compared to air filled tires.
Things to consider before going for it-
Nitrogen filling process is a time taking process as Nitrogen service provider has to bleed out the air completely before filling, now a days many service providers keep automated systems which by themselves go through several purge cycles without any assistance to reach desired purity index. Also you cannot reach 100% purity level with nitrogen inflation and to obtain benefits from it you should reach 95% purity at least. Use of vacuum pumps for bleeding air out is never been suggested as it damage the structure which can really affect the performance of the tire.
