Is nitrogen better for your car tires than regular air?

Answer 1

In Alaska. Good idea.
In California? Waste of money.

Nitrogen gas doesn't shrink when cold. And there to is no water vapor in it to freeze.
And it doesn't expand too much when hot.

Answer 2

Consumer reports did a test and nitrogen tires deflated a little slower than air. Thus, if the tire shop provides free nitrogen then it is worth it, but it is not worth it to pay extra. Nitrogen will only improve fuel economy if you didn't fill up your tires with air as often. Either nitrogen or air at the same pressure will give you the same gas mileage. As for the ride, it doesn't change it unless the tires are over inflated.

Answer 3

Yes and no.

Objectively, absolutely speaking: yes. Just google "nitriogen tires" and read to your heart's content -- there are concrete advantages to using pure nitrogen rather than "air" which is merely ~80% nitrogen.

Effectively, practically, and economically speaking, no. In the typical lifetime that you will have a tire on your vehicle (2-4 years), you will spend way more on keeping it full of pure nitrogen than any notable benefits. If you are likely to be storing your vehicle for long preiods, and thus having tires for more than the typical 2-4 years, the nitrogen might make slightly more sense. "Might" and "slightly" being the operative words...

Answer 4

Nitrogen does not expand and contract under temperature change like air, Tire pressure will remain closer to proper levels than with air, Air pressure can change by as much as20% in differing thermal conditions, and air usually contains high levels of humidity that will condense in the tire when cold.

Answer 5

The nitrogen molecules are larger and the tires maintain their pressure more constant. That's why the racers use nitrogen. As for regular street drining I doubt if it makes a whole lot of difference. You aren't running down the straights at 200mph, so air is fine, it's less expensive, and easier to find at the station. good luck.

Answer 6

The only thing that nitrogen does in tires is keep them from dry-rotting as quickly, because it dosen't allow moisture in the tire. I worked with cryogenics for a while, liquid nitrogen, oxygen, helium. We never put nitrogen in the tires. Besides where are you going to get nitrogen? It ain't sold at the auto parts store!

Answer 7

Technically, yes. Nitrogen is inert, meaning that it won't affect the rubber inside the tyre (air tends to dry out the rubber over time) - this is one reason why professional race teams often use it (when the rules allow it.) However, it also expands at a different rate when heated, so your cold pressures won't correspond to the correct hot pressures..

Answer 8

Yes because nitrogen is more inert so its change in volume is less than air. This mean your tire pressure will stay constant as temperature changes.

Answer 9

try helium for a real "light" ride

Answer 10

no, this is a wive's tale!
