When I had my Ranger, I purchased a new set of tires a month after and they were filled with Nitrogen for free so I said what the hay. 3yrs I never had to recharge my tires period, I recharge my Jeep tires weekly with regular air, when I get my new tires they will be filled with Nitrogen.

 

i use nitrogen, not that i believe the hype, but i have access to it for free so why not? plus thats what they put in aircraft tires so its gotta be good! lol

it doesnt leak as bad as air and the pressure remains much more constant since it doesnt expand and retrcat with different temperatures like straight air does

 

ALL gases expand/contract with temps.

 

how much does this stuff cost? I've heard its around $65

 

Around my neck of the woods, the price ranges from free (with tire purchase) to between $20 to $51 for four tires.

 

3% isn't very much difference. Now if oxygen was 30% smaller than nitrogen, I'd consider that much smaller. But 3%??

 

if you have to add air weekly its a tire/ seal issue, not the air youre using.

the reason they use it in aircraft tires is due the the extreme temp changes an aircraft endures during a flight, something that not many, if any passanger vehicles ever endure. i laugh at the nitrogen craze. who ever though of selling something for 20-50 dollars that you get for free (with the air we breath being made up mostly of nitrogen) otherwise is a genius because they knew people will believe anything they see on tv. there is no doubt it has its benefits but its not worth anywhere near what they charge for it, its just another way to scam money out of people that dont know any better.

 

I fill mine with skittles! Taste the rainbow!

 

I fill mine with Megan Fox's farts

 

girls dont fart so your tires must be flat!

 

ha ha

 

Unless you live in an area that will see below 0 temps for an extended period of time filling your tires with Nitrogen is pointless.

 

WTF??!! LMAO!!!

 

I'll keep my air, its free :-D

 

I filled my tires with nitrogen and got an extra 6mpg and my f150 rides like a caddy.
Then I put a tornado in my intake and got another 6mpg and 50HP.

 

I run regular air so when I am being chased by people I can drive into water and breath off of the air in the tires.

 

ROFL!
