Often asked: Why Inflate Tires With Nitrogen?

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.

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.

How often should I put nitrogen in my tires?

Usually, a tyre loses approximately 1.5 psi of pressure every month on normal air which can be expected across 2-3 months on a nitrogen filled tyre. So, ideally, you should refill your tyres every 2 -3 months if they’re nitrogen inflated.

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.

Is nitrogen better for tires than air?

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 in tires really work?

Fact: Tires naturally lose small amounts of pressure over time whether they are filled with compressed air (oxygen) or nitrogen. Since nitrogen does not completely eliminate temperature-related pressure changes under normal driving conditions, it is of little benefit to vehicle owners who properly maintain their 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 much does Costco charge to fill tires with nitrogen?

Nitrogen is free at Costco and at some car dealerships we called, but these are rare cases. We called a number of tire shops that carry nitrogen and found that the prices for a nitrogen fill ranged from $7 to $10 per tire.

How much does it cost to fill Tyres with nitrogen?

The typical charge for nitrogen is between $5 and $10 per tyre for a passenger car. Once your tyres are filled with nitrogen it’s important that only nitrogen is used for top up purposes.

Is tire pressure the same with nitrogen?

There is no difference between standard compressed air and compressed nitrogen when filling your tires. Refer to your owner’s manual or the tire specs for the Pound per Square Inch (PSI) for your specific tires.

Is nitrogen a flammable gas?

EMERGENCY OVERVIEW: Nitrogen is a colorless, odorless, non-flammable gas, or a colorless, odorless, cryogenic liquid. The cryogenic liquid will rapidly boil to the gas at standard temperatures and pressures. The liquefied gas can cause frostbite to any contaminated tissue.

How do I know if my tires are filled with nitrogen?

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 nitrogenfilled 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.
