Tire Pressure: Nitrogen or Compressed Air for Your Tires?

Maintaining correct pressure is the number one factor for your tires to last as long as they are designed to. However, in recent years, an alternative to the conventional air we use at gas stations has emerged: nitrogen. At mantallanta.com, we want to explain the real differences so you can decide what is best for your vehicle.

What is the technical difference?

The air we breathe and commonly use to inflate tires already contains approximately 78% nitrogen and 21% oxygen. Professional nitrogen inflation raises that purity to 95% or more, almost completely eliminating oxygen and moisture.

The 3 major advantages of Nitrogen:

  1. More stable pressure: Nitrogen molecules are larger than oxygen molecules, which means they escape less easily through the porous structure of the rubber. A tire filled with nitrogen maintains its correct pressure for much longer.

  2. Less heat build-up: Nitrogen is an inert gas that does not retain heat in the same way as moist air. This is vital on hot roads like those on the Ecuadorian coast, as it prevents pressure from rising dangerously during long journeys.

  3. Internal protection: By eliminating oxygen and moisture, internal oxidation of the tire's steel belts is reduced, and the pressure sensor (TPMS) is protected if your car has one.

Is the extra cost worth it?

While compressed air is usually free or very cheap, nitrogen has a cost per tire. It is worth considering if:

  • You frequently take long road trips.

  • You have a high-performance or sports vehicle.

  • You tend to forget to check your tire pressure monthly.

Important: If your tires have nitrogen and you need air in an emergency, you can mix them. There will be no negative reaction; you will simply lose the benefits of nitrogen's purity until you perform a complete inflation with the pure gas again.
