Can tires be inflated with nitrogen?

Since nitrogen molecules are bigger than normal air molecules, it is harder for them to leak out. This means a tire filled with nitrogen will maintain air pressure longer. Therefore, they say, you’ll roll on tires that are always properly inflated, resulting in better fuel economy and longer tire life.

Does nitrogen filled tires make a difference?

The results show that nitrogen does reduce pressure loss, but the reduction was only a 1.3 psi difference from air-filled tires over an entire year. “Our test showed that while nitrogen has some advantages, both nitrogen and air-filled tires lose pressure over time,” Pszczolkowski says.

How much should nitrogen filled tires fluctuate?

In general, you can assume that your tire pressure will fluctuate roughly one pound per square inch (psi) in accordance with a 10° Fahrenheit change in temperature, and under inflated tires will reduce your gas mileage by 0.3% for each 1 psi drop in pressure for all four tires.

How much does it cost to fill your tires with nitrogen?

If you purchase a new vehicle and want nitrogen-filled tires, you can expect to pay anywhere from $70 to $175. If you would like to fill existing tires with nitrogen, the initial fill-up will cost about $30 per tire. That’s because the existing tires need to be purged of their oxygen with multiple nitrogen refills.

Do nitrogen tires go flat in cold weather?

Even though nitrogen is not as “reactive” as regular compressed air, you can still expect to lose about 2 percent pressure for every 10 degrees F in temperature reduction. great for your customers AND your technicians as nitrogen filled tires, wheels and related hardware are always dry, and rust and corrosion free.

How long do nitrogen tires last?

On average, tires filled with air lose about 1.5 psi every month, whereas tires filled with nitrogen will lose that amount in about 3-4 months. You will likely have to top off your nitrogen filled tires less often than if they were filled with air.

Can you mix regular air with nitrogen in tires?

It IS okay to mix air and nitrogen, such as when you’re topping off your air-filled tires with nitrogen, or want to fill them with nitrogen without purging them of the air. You can’t have a mixture every now and then, but primarily use regular air.

Can I mix nitrogen and regular air in a tire?

It’s never a good idea to drive on an under-inflated tire. Using compressed air in tires that have previously been filled with nitrogen will not harm your tires. While mixing the two won’t result in an adverse chemical reaction, it will dilute the purity of the nitrogen and lessen its effectiveness.

What are the benefits of nitrogen filled tires?

In this scenario, nitrogen-filled tires are advantageous because nitrogen gas doesn’t support moisture or combustion. Compared with ambient air – which contains roughly 78 percent nitrogen, 21 percent oxygen, plus miscellaneous gases – pure nitrogen is an inert, non-flammable gas.

How do I know if my tires have nitrogen in them now?

How do I know if my tires have nitrogen in them now? The most common way to determine if your tires have compressed air or nitrogen is by the color of your tires’ valve caps. A nitrogen-filled tire will likely have a green-colored valve cap or include an “N2” emblem.

What’s the myth about inflating tires with nitrogen?

Myth: The lack of oxygen and moisture in a tire filled with nitrogen reduces the potential for chemical deterioration of the tire liner, and limits the possibility of rust and corrosion on the wheel. Fact: Compressed air systems at most tire shops have moisture separators that limit the amount of water vapor in the compressed air supply.

What’s the difference between compressed air and nitrogen in tires?

Myth: Nitrogen does not leak from tires as quickly as compressed air, and therefore maintains proper tire pressure for a longer time. Fact: Tires naturally lose small amounts of pressure over time whether they are filled with compressed air (oxygen) or nitrogen.
