Nitrogen in tires....(Warning. Unscientific test inside)

Sir you need to get a hobby

 

this IS his hobby-

 

I thought his hobby was more blowing things up and lighting stuff on fire?

 

im interested to hear the results. I know jeep guys who swear by nitrogen in the tires for permeation loss and also for less psi fluxuation at differing altitudes. personally, i think they just like to tell people they put N2 in their tires. great idea for a test btw.

 

No no no
Its catching and releasing spiders

 

Hey Chris I am with you on this-never needed that crap in our tires till someone stuk it out there as the "it" thing. Besides-isnt air 78% nitrogen anyways?? So you're only increasing your nitrogen 20%

 

No that his funtime-this is when he's thinkin about stuff

 

I'm hoping this experiment will get to that point after the preliminary testing is done.

 

Ironically, most TPMS sensor corrosion is cause by moisture in the air

Only benifits of Nitrogen are:

1) Less permeable through rubber.

2) Less expansion and contraction (As Chris stated, more from moisture then anything). Also, Nitrogen technically DOES expand and contract less then PURE O2 (Notice the pure, the tests conducted in my textbooks mentioned this), but this effect is so small its neglegable. There is a ratio of nitrogen expantion table vs temperature in my Power engineering books.

3) Nitrogen is an inert gas, meaning it doesn't burn. which means fuck all when your tire explodes in a real world environment. I actually once had a dodge salesmen try to tell me if my vehicle was ever on fire to the point that my tires would explode, that the nitrogen in them when they burst would not fuel the fire.... I laughed at him and said if my vehicle is on fire to the point of tires exploding, insurance will buy me a new one.

 

In a place like Charleston SC where the humidity is rediculous, I believe N2 does make a differance.

 

YES, most people do not realize that--guess they want a few more bucks to put air in your tires--trying to justify the extra cost--WHAT A RACKET--

 

Rent a plane for an afternoon and test at 40,000 ft

 

Is that a challange?

 

Actually air has 78% nitrogen already so how could adding a measly 18% more nitrogen make a frikkin difference?

 

Don't forget the heat. A tire gets hot during driving and the gas is affected by the heat. That constant expansion is a key to using nitrogen over plain room air.

 

But the dealerships are using it as a gimic. It is effective in airplane tires.
