i heard that its better but i cant tell

 

I'm not running in it my oem rims cause i just dont care. but in all my aftermarket wheels i am running it...

 

UNV where do you get yours done at and how much if you dont mind me asking...

 

Not sure if this is true but I was told by the guys at the tire shop where I had my nitro filled that Nitrogen also prevents oxidation to the inside of the rim. Not that its going to make a huge difference either way.

 

Aircraft tires, commercial and military, use nitrogen for the reasons given..temp, heat expansion and no water vapors.

I bought new tires for my truck at Costco a few months ago and noticed they put green air valve caps, the green caps mean the tires were filled with nitrogen.
