Quick Answer: Why Nitrogen In Tires?

Can you put air in a tire filled with nitrogen?

It is FALSE that air cannot be used to top off a tire filled with nitrogen. It is simply not true that air and nitrogen cannot coexist inside a tire. There is no harm in topping off a nitrogenfilled tire with regular air.

What are the pros and cons of nitrogen filled tires?

Having the correct air pressure optimizes your fuel economy. Higher tire pressure results in better fuel economy because it reduces rolling resistance, and because nitrogen stays in your tires longer, you won’t have to work as hard to keep them properly inflated, making it easier to get your best fuel economy.

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.

Does cold weather affect nitrogen filled tires?

Nitrogen is a gas and is still affected by changes in ambient temperature (about one psi for every 10° Fahrenheit). Nitrogen filled tires will require pressure be added during the fall/winter months as ambient temperatures and tire pressures drop. Nitrogen is good but can’t change the laws of physics.

Are nitrogen tires worth it?

CR’s tests show that using nitrogen is not worth the money or inconvenience. 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.

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.

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

On new car tires, the cost can range from $70 to as much as $179. On existing tires, you’ll pay up to $30 per tire for service to drain air and refill with N2. Refills will run you $5 to $7 per tire, which you can expect to do less often than with air-filled tires.

Why do dealers overinflate tires?

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. It is supposed to be part of the delivery check process that the service department deflates the tires to the proper pressure.

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.

  1. A nitrogen-filled tire will likely have a green-colored valve cap or include an “N2” emblem.
  2. A typical air-filled tire will have the more traditional black or chrome valve cap.

Is nitrogen-filled tires a gimmick?

Paying to fill your tyres with nitrogen is a scam. That’s 50 million tyres. They’re wearing out every four years – let’s say – and most tyre retailers are busily dry-humping your leg to get you to spend – $10 per corner – to pump up with a miraculous gas: pure nitrogen. It’s potentially a $100 million consumer scam.
