Has anyone inflated their tires with Nitrogen yet?

It is suppose to be lighter than air,,, bigger particles, No leaking and dosnt turn mosit in your rims?

A shop here has it, and charges $5 per tire to fill. Also said you can mix air with it if your in a pinch.

Thanks.!

 

I thought about it before, but the it ended up being to hard to find a place that was willing to do it. It ended up not being worth the effort for me.

 

i have nitrogen in 03 evo i had them filled up at tire discounter when i had a flat tire fixed it has been awhile ago but still holding up fine

 

interesting. I have never heard of this before. I will have to look up what the exact weight differences are...

 

My local Costco has nitro fill on their tires that they install and they don't seem to charge any more for the service. The nitro allows the tire to hold inflation pressures for a longer period of time and the molecules are larger. but $5 per tire is too much.

 

The main reason for filling your tires with notrogen is that when you get your tires hot (like autocrossing) your tire pressure doesn't rise as much as it would with air.

There is no appreciable weight savings. You would probably lighten the wheels more by cleaning the brake dust off the inside of the wheel.

 

I order Nitrogen bottles for my job all the time(USAF), we buy the standard 220cu/feet bottles for only $17.00 from a company called Praxair. I am sure you can buy them much cheaper locally.

Whomever is charging $5 a tire is making a huge profit, the bottles ususally last a lot. By charging you $5 per tires they are paying their bottle entirely.

Ridculous!!

 

How about helium?

 

so..im pretty bored: Nitrogen is about 1.81 pounds lighter than air, pound for pound...so it probably wont make much of a difference if any...(7 pounds)

 

Hindenburg revisited.

 

That would be hydrogen. Helium is inert.

 

I think your math is wrong. The air we breathe is already 60 percent nitrogen. It is going to be the amount of water vapor in hte air that makes the biggest difference in weight and most compressed air has been through some type of drying process so that is almost a mute point. There is no way you are going to save 7lbs of weight by filling your tires with nitrogen.

 

the 1.81 pounds of difference is between the molecular mass of air and hydrogen...

 

Ooops..but hydrogen would be very light, huh? LOL

 

I never said compressed air....there will probably a change in weight with compressed air, I couldnt find any numbers on this figure in 2 minutes
