Nitrogen for tires?
Has anyone thought about trying this? I know aircraft use it and racing teams use it too. Thetire pressure is not supposed to be effected by heat/cool and since there is no oxygen or water vapor thewheels and tires are supposed to last longer. Of course I also heard it costs about $10.00 a tire. Any thoughts?

RE: Nitrogen for tires?
this topic has been beat to death a bunch of times here. it's awesome. my mom's 2004 grand prix has never needed to have air added in over 2 years. $5 per tire. if nitrogen wasn't the way to go the military wouldn't buy the high dollar nitrogen generating carts for strut and tire inflation.

We used to use it in racears when we ran ashpalt ovals, but there's not enough temp change in street tires.
$10 a TIRE!
Holysh1t! I used to get huges "bottles" (like a welding tank) for $20 and they would last several months / bottle. Perhasp I should get another bottle and start an "Air Change Service".... $$$$$$$

Nitrogen will expand like any other gas when heated (Charles Law) - the only difference between air and nitrogen is the nitrogen is probably (emphasis on probably) dry - water vapor is what will cause wide variations in tire pressure - not nitrogen. Find a way to dry air and it'll behave the same way. Snake oil at it best - think I'll try selling water in plastic bottles - think anyone would buy it if I mark it "pure".
