Well guys, the Grey Ghost is about ready for new tires. I've been seeing a lot of tire places here in Louisiana offering Nitrogen for tire inflation. Would appreciate hearing the pros and cons of it. Thanks!
I think its a waste of money. What are the benefits? Less moisture? Tires don't last long enough to rot from the inside. More consistent pressure? Not really a factor unless you're racing or something. MPG difference from very slight pressure differences is negligible in a truck. Unless its extremely cheap, I don't see how it could pay for itself.
In my work, I see well testing done with nitrogen all the time. Down side is, just the sun shinning on the hoses to the pressure recorders cause the nitrogen to expand and contract quickly making a stabilized test hard to run. The sun pops out fromm behind a cloud and the pressure jumps 20-30 lbs (on a 500 PSI test), sun goes behind a cloud, pressure drops that much (that's 16% each way, or almost 6 PSI in a 35 PSI tire). The only benifit in it's use for what we do is (1) Non corrosive, (2) Not explosive in the pressence of hydrocarbons. They use it because of it's expansion factor , allowing 1 large tank to test several wells. I can't see any benifit at all for tires, am I wrong???
while i wouldnt pay for it in my truck, the benefits are mostly that it doesnt fluctuate pressure as much as compressed air and the nitrogen molecules are much larger than that of whats in the air we breathe, therefore it doesnt slowly leak out like regular compressed air does. however something like 60% of the air in our atmosphere is already nitrogen anyway
i would however use it in my motorcycle tires, only because tire pressure is far more important in it than on a car/truck. it only gets run on the racetrack at full tilt, never on the street
my dad worked at goodyear as a retread engineer and i know for a fact that they put nitrogen in all the semi tires that they retreaded and all the new ones that they sold. And i also no that anyone of us can go out and buy an air compressor that turns air into nitrogen...well extracts the nitrogen. and they shouldn't charge you for it! i know my dads buddy in cincinatti just got one of these machines at the shop he works at and they don't charge to use nitrogen instead of air!
