What's the biggest benefit??? It was on the news, but I couldn't stick around to watch it. Some tire places uses it instead of plain air.

 

Nitrogen has less tendency to expand/deflate with changes in temperature. Also less likely to deplete itself through the tires.

 

I just got talked into using it when having Avons (from Tire Rack) installed. The benefits indicated to me were...
-less expansion/contraction due to temperature swings
- the normal tendency of air to seep out is reduced with NItrogen
-in event of a blowout- is supposedly is a more controlled release??
The selling point that they got me on what that it reduces the oxidation of the pressure sensor monitors in the wheel (which are very, very expensive).

I did follow up with Tire Rack, and they indicated that there were some benefits to Nitro, but probably not worth paying extra for, as there arent' many Nitrogen air filling stations available if you need to add air. I paid $6/tire, with free fillups for life. I probably would not do it again (as I don't plan on keeping car long enough for pressure monitors to oxidize/fail).

 

The tire pressure thing is absolute BS.

 

PV=nRT

 

lol @ PV=nRT
dont you love physics? hahaha
i havent put nitrogen in my G but i have em on my other car, maxima (michelin PS2)
i dont think it is necessary for area where i live in, VA.
