Can You put Air in a Tire Filled with Nitrogen?

Nitrogen in Tires is used in tires to provide a level of inflation that is stable and predictable, as well as responsive handling and longer tire life.

Tire manufacturers and the government make it a priority to educate consumers about the benefits of using nitrogen in tires, but there are still several myths about this practice circulating the market today.

Can you mix air and nitrogen in your tires?

You can but it is not recommended because Nitrogen is inert and does not react with the other components of air, which can cause corrosion in your tires. Nitrogen is also heavier than air, meaning your tires will take longer to go flat.

Less gasoline will evaporate due to the lower temperatures when tire pressure is greater due to nitrogen. Lastly, you’ll greatly reduce wear on suspension components by using nitrogen because it doesn’t heat up as quickly as air does when under pressure.

Most technicians are not trained to refill tires with nitrogen because of the specific tools and equipment it requires. For instance, tires need to be plugged on the inside so that nitrogen can get in, and a specialized computer valve that looks more like a child’s toy car will do the trick.

It’s not expensive to use nitrogen in your tires, but you’ll need to find a shop or technician who can do it for you. If you are considering this as an alternative to using air in your tires, be sure to talk with your tire experts first about the pros and cons of using it. Find out what equipment is required and how much it will cost.

Can you fill a tire with air when nitrogen is in it?

You may be tempted to fill your tires with both air and nitrogen to see if there is any difference in the way it feels. But you should know that nitrogen will not escape from mixed tires, so you’ll have nothing to compare. It’s also important to remember that the air around you contains 80 percent nitrogen if you are wondering how much of it is inside your tires.

Does tire pressure fluctuate with nitrogen?

Because nitrogen is heavier than air and does not evaporate quickly, tire pressure will not fluctuate as much with nitrogen. Older tires could be a problem, however. Tires may become over or under-inflated over time due to the wear and tear they endure.

It is more difficult for the equipment that fills your tires to regulate pressure in an older tire because its treads are no longer even. This makes it harder for equipment to detect the actual pressure inside the tire and the amount of air needed to fill it.

If you use nitrogen, this will not be a problem as you will have a more even distribution of weight in your tires, keeping them properly inflated at all times.

How do you tell if you have nitrogen in your tires?

You know you have nitrogen in your tires if you see the following three numbers on your tire’s sidewall: 13032 (That is the first three numbers, “13,” in the DOT code) Your tires are filled with nitrogen if they read a 32 (the second set of three numbers, “32”).

If you do not see those letters in your tire’s sidewall, then you do not have nitrogen in your tires. If you see any other combination of letters and numbers, that’s how the tire was inspected when it was made. But it doesn’t say anything about gas being used to fill the tire.

Is it worth putting nitrogen in your tires?

Nitrogen is more expensive than regular air. As of this writing, nitrogen costs about $2.50 per tire, while air is around $1.50 per tire.

It also costs more to have tires refilled with nitrogen because of the extra equipment required to plug the tires and add the gas.

Most vehicles are designed for air pressure in their tires, so you may not notice any difference between using air or nitrogen in your tires unless you are looking for it.

That’s why some people decide it’s not worth it to use nitrogen in their tires. Whether or not you should fill your tires with nitrogen boils down to a matter of personal preference and cost-effectiveness for your situation.

Can I fill my tires with nitrogen at home?

It is possible to fill your tires with nitrogen at home. It’s a small, lightweight cylinder that you can plug into the tire’s valve stem and it will fill your tire with nitrogen. Whether or not it’s cost-effective is another story.

You can find these small cylinders online or at some local retailers. It will cost about $40 – $50 for the cylinder and about $20 for each refill of your tires.

If you have a few extra dollars to throw around, you might want to buy one of these and see if you notice any difference in handling between using air and nitrogen in your tires.

What are the disadvantages of nitrogen?

  • Nitrogen is more expensive than air.
  • It will take longer to go flat because the pressure is regulated better with nitrogen.
  • It takes more work for technicians to fill tires with nitrogen, so costs can increase when you need it done.
