what bnefits are there in using nitrogen in tyres?

Answer 1

Nitrogen is less susceptible to overheating than plain air (because it's denser). It also has larger molecules than many of the molecules in air, so it doesn't leak out through the tires as easily.

It's also moisture-free, so there's no water-related breakdown of steel belts in tires or the rubber itself.

EDIT: For those who can't conceive of a difference: Auto racers use pure N2 tires now because of all of the reasons above. In a sport where hundredths of a second means huge differences in prizes, they have a strong incentive to find and exploit any advantage they can. If they didn't use it, it'd be because it doesn't work.

Answer 2

Military aircraft tyres are inflated with Nitrogen. It is a dry gas and so there is less chance of water triggered corrosion in the steel belts and wheel hubs. It is less prone to volume changes that air when heated so that the pressure remains more constant during the operating cycle where the temps can vary a great deal (very cold at 30,000ft then gets hot rolling around the runway on landing.)

Answer 3

Very little. Consider....if you put air into the tire you are already putting in 78% pure nitrogen. Consider the cost to put in 99% pure...There will be less oxygen so the inside steel rims may rust less. There is air all around the outside of the tire though!

Answer 4

As far as I know we alredy have about 78% Nitrogen in our tyres. I cant see that another 22% would make a great deal of difference.
However if your tyres caught fire they might extinguish more quickly.

Answer 5

It benefits the dealer,not you.It's a money maker for them.
Tires need pressure.It doesn't really matter what kind of gas is applying the pressure,just as long as it's not explosive or corrossive,and the tires remain inflated.
Buy an air gauge,check the pressures yourself when you top off at a filling station,and save some of your money.

Answer 6

Racing cyclists will tell you that the weight differential between pure nitrogen and regular air mix is enough to give them an "edge". Personally I have difficulty in believing that (euphemism, I think it has to do with some aged gentlemen who mend shoes).

Answer 7

From what I know, nitrogen does not expand and shrink as much as oxygen does so the volume of your tire stays relatively the same over time.

Answer 8

I can't think of a single one. Air is 80% nitrogen anyway.

Answer 9

I guess cause it's not subject to so much change in air temps.
