Tires are an essential part of your vehicle. It is essential that they have a correct condition and adequate pressure so that you can circulate safely on the road .
Bad wheels can cause a serious accident. Therefore, it is recommended that you monitor their condition from time to time, especially regarding their wear, that they present protrusions, and that the pressure itself is correct.
Precisely for the sake of improving their performance, in recent times a debate has started among automotive experts about whether it is better to use nitrogen or air in the tires to inflate them. And it is not an inconsistent discussion, but it has a lot of substance.
Nitrogen or air in the wheels
You may not have ever heard or read about this debate, but it is becoming more and more common. And there is nothing wrong with inflating tires with air, but nitrogen has a number of additional advantages. First of all, it is a more stable gas than traditional air. This means that it is less prone to pressure changes.
In hot weather, tires wear more and their pressure increases, while in cold weather the opposite happens. Therefore, the more stable the gas inside, the easier it will be for those changes to soften and, ultimately, for the wheels to be in better condition. Being subject to fewer variations, the tires will offer you better performance in terms of grip, noise and even fuel consumption.
The problem with air is that it has a high degree of humidity and, in the heat, it evaporates, raising the pressure of the wheels. On the contrary, if the temperature is low or you use the car little, that humidity condenses again by lowering the pressure of the tires. These variations can pose a risk when driving your vehicle.
For its part, nitrogen is drier. Therefore, it avoids those problems of evaporation and condensation. Its lack of moisture helps you prevent the oxidation of some tire components, in such a way that it better preserves its flexibility and other properties.
Advantages of inflating tires with nitrogen
So, inflating tires with nitrogen has a number of advantages. In addition to the aforementioned that it offers greater stability in the pressure of the wheels, the following should be noted:
- Tires are less sensitive to changes in temperature.
- They grip the road more and have a better behavior.
- They save fuel and emit less CO2 into the atmosphere, with the protection of the environment that this implies.
On the contrary, inflating the wheels with nitrogen is more expensive than doing it with air, although it is not too expensive either. Inflating the four tires usually costs about 12 euros (4 for each and the spare wheel free). Almost all auto repair centers already have nitrogen cylinders. Likewise, this gas is suitable for the tires of any type of car.
However, before deciding between air or nitrogen for the wheels, you should know that the former is recommended for sports vehicles. That is to say, those who travel through circuits and whose tires are subjected to a greater effort than usual. Otherwise, it will not compensate you to use nitrogen for the wheels, since its benefits are imperceptible in daily driving and it is more expensive.
What you should never forget is that the tires have to be checked periodically to check that they are in good condition . It is a matter of minutes, it does not cost any work and, if you do not do it, you run the risk of suffering a serious accident.
And you have to do it regardless of whether the wheels are inflated with air or nitrogen. As we told you, the latter is more stable and, therefore, it is more difficult for the tire pressure to change due to the weather. But you can do it for other reasons such as a poor condition of the valve or a leak in the tire itself.
You should also know that, if you decide on nitrogen, you find that the pressure of the wheels has dropped and you go to a workshop where they do not have that gas, you can mix air and nitrogen without any problem. This will not damage the tires.
