Why do they use nitrogen in tires?
This common pitch is compelling: Filling your car’s tires with nitrogen will reduce air loss, boost fuel economy, reduce rolling resistance, and improve safety.
Some cars are even sold with the telltale green caps on valve stems, signaling the tires have already been filled with nitrogen..
How do you tell if you have nitrogen in your tires?
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.
Why do dealers overinflate tires?
Did you check the pressure after driving the car while tires were warm or did you check pressure first thing in morning when tires are cold? Tires are overinflated during the shipping process, so as to help prevent the flat spot from forming in the tire as it sits for days on in during the shipping process.
Is nitrogen a flammable gas?
Nitrogen gas is colorless, odorless and non-flammable.
How do you fill up a nitrogen filled tire?
How to Add Air to Nitrogen TiresRemove the hubcap that protects your tire’s valve stem. … Locate the valve stem. … Remove the valve stem cap. … Place the tire pressure gauge over the valve stem. … Turn on the air compressor. … Hold the air compressor attachment on the valve stem for approximately 15 seconds.
How much does nitrogen cost?
For example, a gallon of liquid nitrogen costs just $0.5 in the storage tank. But, the cost rises to $2/gallon it delivers in Dewar flasks.
What are the pros and cons of nitrogen filled tires?
Better MPG.Nitrogen filled tires bleed pressure slower than compressed air. Properly maintained tire pressure is essential for tire wear and gas mileage. … Longer tire life. … Oxidation is blocked.Oxygen causes oxidation. … Nitrogen is a green alternative.Nitrogen has the potential of being greener for the world.
What are the disadvantages of nitrogen?
Disadvantages of Nitrogen: Nitrogen inflation is quite costly when compared to oxygen. … Maintenance of nitrogen filled tyres is also quite tricky because once you have filled nitrogen inside your tyres, it is necessary that you have to use only nitrogen whenever you are up for an air filling.More items…•
How long do nitrogen tires last?
about 3-4 monthsOn 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.
Where can I get nitrogen to fill my tires?

Is nitrogen better for tires than air?
First is that nitrogen is less likely to migrate through tire rubber than is oxygen, which means that your tire pressures will remain more stable over the long term. Racers figured out pretty quickly that tires filled with nitrogen rather than air also exhibit less pressure change with temperature swings.
Does nitrogen tires increase gas mileage?
Nitrogen tires get better gas mileage. … Nitrogen tires need to be filled less often and maintain higher pressure, making them last longer, which reduces tire replacement costs. Oxidation from tires filled with oxygen can reduce your tire life – so you should use nitrogen to extend the life and save money.
Does nitrogen in tires do anything?
The main benefit of nitrogen-filled tires is that the loss of tire pressure is slower, because the gas in the tire escapes more slowly than air does. With more stable tire pressure, the thinking goes, you’ll get better gas mileage and get full tire life since you’re always rolling on fully inflated tires.
Can you put air in a tire filled with nitrogen?
Mixing air and nitrogen won’t cause any damage. … Nitrogen and air get along very well. When you fill your tire from an old-fashioned compressor at the local gas station more than 78 per cent of it is nitrogen. The rest is oxygen (21 per cent) and a minuscule amount of miscellaneous gasses.
