I am doing some research on air (for tires) I know about nitrogen but I did some research and I think nitrogen is heavier than air. Then I thought about helium I found out it is extracted from natural gas (hope it isn't still flammable) but do you think it will expand? And is my theory right?

 

That would be very dangerous since you have hot tires with a very flammable gas. I think it would probbly blister your tires then pop them?


Anyone else chime in I am just speaking with no research just a therory

 

I am pretty sure helium is not flammable. However the reason for using nitrogen is for the consistent lack of increase in pressure due to the water vapor present in air. Air is actually about 78% nitrogen anyway.

 

yes nitrogen is more dense then air......hellium is less dense and "lighter" i guess you would say.....But IMO why would u want "lighter tires"..... also hellium is'nt flamable , it is an oxidizer though. and yes hellium does expand, as with all other gasses if heated.

+1 on air being 78% nitrogen.

 

why wouldn't you want lighter tires? Ligher rolling resists I don't to much to make a difference but if it is lighter than nitrogen and air why not

 

nitrogen is generally used for stability, especially in aircraft tires.

 

i guess if u wanted to do a 1/4 burnout

to each his own though.

 

1/4 burn out?

 

i was saying that you would spin ... i was being sarcastic
