Helium is also a non-flamable gas. The Hindenburg was filled with Hydrogen, which likes to go boom.

 

i fill my tires with SLIME* 20LBS of it and i can run over nails and watch my tires ***.

ok,nitrogen would be good for shops that way there not filing dumasses tires every 2-3 weeks and the shop could save time but probally lose money unless they charge the costumer for it.

 

Sorry, I stand corrected. Scott, I fucked up

 

**** happens.

 

Jay I do agree with you on most points. Nitrogen doesn't get better mileage or anything, thats obvious. Nitrogen or not, hardly anyone around here would inspect their tires while they fill them. That's the thing, we check about 20-30cars air pressure a day. Not one of those people get out of the car, because they don't care. They tip us $5 when the gas station pump costs just 25 cents. As long as the tire looks round and inflated, their happy.

Most cars today come with pressure monitors, and in a few years they will be required by law (on new cars). People are getting lazy and nitrogen ads are taking full advantage of it. I know nitrogen helps, I see it every day. Is it worth the extra money?...meh. I know what your saying and I agree, but the average person does not.

 

:gay:

 

shouldn't this be in general miata?

And I have nitrogen in all my tires because that's the way the 6ul's come.

 

inert gas, the seductive killer.

 

in any case I don't think it's bad, no one who is negligent enough to not notice a screw in the side of their tire because it has nitrogen isn't any less negligent with non-nitrogen filled tires.

Jay i don't think there's a point in getting all riled up about it. Any way you chalk it up it's capitalism and it works. Koto, you can still read the air pressure, if nitrogen didn't react the same way air does then air wouldn't work either since more than 3/4 of all air is nitrogen. The only difference I can see would be that the tire temperature might be harder to figure but that would just be calibration anyway.

 

Riled up? Dude I'm as calm as a hindu cow.

 

helium is lighter and makes your voice weird...

 

IIRC, air is something like 60-70% nitrogen, so you probably wouldn't be compromising an all-nitrogen fill too badly by adding air to adjust at an autocross. If I nitrogen readily available, I'd proably use it.

I doubt that anybody on this forum needs to worry too much about tires lasting long enough to dry-rot from inside .

 

but would it be benificial to mix helium and nitrogen and put in your tires? nitrogen is 70% of what air is, but heilum is not. so i guess to make the question go in a different direction, what would happen if you filled your tires with soley helium? Helium is the second smallest element on the periodic chart thingy so its technically the second lightest right? and since its an inert gas it shouldn't blow up. so would 37-40 psi of helium reduce unsprung weight? the gas in your tires would be lighter than air, so you would think it would have a net lightening affect.

of course this wouldn't be feasible for the average miata turbo people because since the molecule is smaller it would leak out of the tire faster, but how come indy cars don't use this?
