What Occurs If I Put Helium in My Tires?

The heaviness of your car is significant regardless of if you are traveling through the winding roads of the Appalachian Highlands or a busy metropolis. As a result, many of us look for methods to make our cars lighter. So, given that helium is less heavy than air, would this be an effective and/or secure technique to reduce the weight inside our vehicle? and using helium to fill tires?

Helium is certainly not a good gas to use for filling a tire. Even though helium remains lighter compared to air, the distinction is not significant. Helium particles may not only be significantly smaller compared to those of air, but they are also barely sufficient light. You can drop tire pressure and only have flat tires as a result of the helium particle passing right through the latex.

What drawbacks are there to filling tires using helium?

Helium is the 2nd lightest component, with anatomical mass of 4.003u as well as a particle number of 2.

The fundamental weight of the atmosphere, on the other hand, is 28.965u, making it almost seven times denser than helium. This second-smallest atom is helium, and here is when things become tricky when we speak about tires.

The helium atoms just go past the tire due to its small size. While not immediate, this leak persists over time. This cannot be avoided in a typical tire. Furthermore, since air is hardly a very dense substance, there is barely any of a weight differential between the air and the car itself.

Since it can’t be generated and is not present in the environment, helium constitutes a finite component. It simply floats upwards and almost disappears off the exterior of the planet due to its size. ExxonMobil serves as the biggest helium generator in the entire globe. In Wyoming, helium-rich carbon dioxide and methane gas deposits are used to extract the natural gas.

Helium is costly because it is limited and for all of these explanations. Too costly to be used as tire filler gas.

Is utilizing helium beneficial in any way?

Oxidation is one problem that air may lead to. Small quantities of water vapor are present in a lot of compressed air. Even if it’s not a lot, the moisture in the vapors will be sufficient to condense onto water fragments and begin corroding the wheel and tread.

Pure helium has one advantage over air in that it is not destructive. Yet, its disadvantages exceed the benefits of reducing corrosion that are simply too severe. But you may utilize nitrogen in the tread to stop rusting. This additionally stops rusting, yet it also offers several additional advantages.

What purpose serves helium?

The five categories of helium’s greatest widespread use are as follows:

Unexpectedly, or perhaps not so unexpectedly, the primary application of helium involves lifting. Yes, wedding balloons plus the like use more helium that any other industry.

NASA plus the US military services employ helium for cleansing, which is the second-biggest use. WD 40 is used for cleaning rim alloys. Helium is largely used to cleanse the clean liquid hydrogen along with liquid oxygen present in the spacecraft’s fuel tanks along with lines.

Helium may be a viable argon alternative when it comes to gas tungsten arc soldering. Stainless steel, titanium, as well as aluminum are the three metals most often joined using this sort of riveting.

Helium has a very low boiling point, making superconductivity an essential part of the MRI equipment. Everything else could simply freeze; it functions as a coolant.

Fundamental studies – For a similar logic, helium frequently serves as a refrigerant for scientific operations at very low temperatures, even as low below a few millikelvins off absolute zero.

Options To Consider, If Not Air

Nitrogen is essentially the only substitute to air for inflating tires. It’s crucial to keep in mind that wheels are made by having air injected into them. Nearly 78% of the air is nitrogen, 21% is oxygen, among the other molecules include CO2 and others. Therefore, switching to the nitrogen isn’t a huge leap.

What advantages does utilizing nitrogen offer?

Helium leaves the tire via the air itself, as was already explained. This also applies to nitrogen as well as air, although air leaves in far smaller quantities than helium. While utilizing air, you typically lose 1-3 PSI every thirty days; nitrogen, still departs much more slowly than air.

It’s crucial to keep the air flow in the tread at the right level. It enables the car to be driven as it was intended to be. Anything from gas economy to tire lifespan to protection is impacted by tire pressure. Absolute nitrogen keeps the tire’s correct pressure more effectively than oxygen does since it cannot escape as rapidly as air would.

Because nitrogen is additionally less thermo-reactive, the inflation of your tires will fluctuate less in response to changing weather and driving circumstances. Because of this, nitrogen has become the gas of choice for racing vehicles and airplanes.

Additionally, nitrogen has no detrimental effects on the tread of your wheel. This process, known as a thermo-oxidative response, does occur in air. Your tire gradually deteriorates as a result of this interaction. When the thermo-oxidative response necessitates a tire shifts, your tire wear should typically degrade to a stage of replacing. 

Yet, this may turn into a problem that might be prevented by utilizing nitrogen when you don’t drive your automobile a lot, as could be the situation with an exhibition car.


Helium is ultimately not a suitable gas for refilling the wheels with. The tire won’t retain the gas even though the substance is less dense than air. The synthetic material of the wheel will only allow the helium to flow out. Nitrogen should be used in the wheels as a replacement for air.
