Tires are designed to give you long miles, the are built to travel many miles with quality service. But the key element here to achieve this is maintenance of tires. Tires need maintenance and caring, for them to perform well. This is done by keeping a proper inflammation pressure. Every car is provided with either a placard or user guide, which has the exact recommended pressure required for the tires of that car.
Now why is nitrogen so special? well the answer is its inert properties. Nitrogen has a very low inflammation rate, due to its inert properties, so filling in nitrogen allows the inflammation pressure to be constant, thus providing a better experience with the drive. What happens is, gases inflate or deflate in summer and winter respectively, thus checking up on the air pressure frequently is quite important.
Pressure should at least be checked monthly, and weekly if the usage is high. Every time you go for trips, remember to check on you tire pressure. Nitrogen is used world wide today in many vehicles, where you don’t have enough time for checking the pressure daily, like army vehicles or race cars. Army vehicles prefer nitrogen because of the type of terrain they have to go through and race cars use it, to keep the inflammation in control.
Even our normal surrounding oxygen we use normally has 78% nitrogen value. Its just that pure nitrogen works better, because there is no humidity in it unlike normal air, as is it dry by its nature.
Question is, does a normal person require a nitrogen filled tire. Well not necessarily, no tire company or car company says that nitrogen is better. Its all on your choices and preferences. If your usage is high, you may consider, if not then its not needed. It is not bad having nitrogen, because there is no harm to your tire in doing that.
Nitrogen will also work good for those people who don’t get time or don’t wan to spend time in checking on the pressure on daily basis.
Also remember nitrogen tire inflation does not harm tires and may marginally contribute to reductions in tire inflation loss by permeation. Nevertheless, nitrogen will not prevent any tire inflation loss caused by punctures, tire/rim interface (bead) leaks, valve leaks, valve/rim interface leaks, wheel leaks, and other mechanical leaks. Again, the use of nitrogen alone does not substitute for the importance of regularly checking tire inflation pressure. If the tire inflation pressure is below the pressure specified on the vehicle placard, the tire must be re-inflated – whether with air or nitrogen – to the proper inflation pressure. Do not operate tires underinflated and/or overloaded.
And one more thing, because nitrogen is less found as compared to normal air on daily basis, many people have this question, if we can fill air over nitrogen in emergency cases. Yes! Top it off! it doesn’t matter, as both are gases, and inert gases which do not react.
The bottom line being, what ever you fill in your tires, remember to check on the pressure daily to avoid any inconvenience.
