I'm still working with the pressures. Most Z drivers that autocross well seem to be running pressures between 37-42 psi depending on their suspension setup. I've found that that 38 seems about right so far, but I'm still tweaking it. 30psi is way too low for DD on the stock tires. It will be a soft ride, but you will have increased tire heating and increased wear.
there is increased wear with overfilling your tires too. Max pressure on the tire is around 40psi so putting them right at that i don't think is a good idea.
I wonder if this guy even know what air really is?
Believe it or not, I actually do know what air is. The question still stands. Compressed air not only has primarily Oxygen and Nitrogen, but also has a fair amount of water vapor. A mix of Nitro fill and compressed air will have an increasing amount of water vapor and oxygen in it every time the tire is topped off with compressed air.
The air we breathe is more nitrogen than oxygen. 21% Oxygen, 78% Nitrogen, 1% Other gases.
I, too, was being sarcastic. I do air cavity analysis as part of an aging program on detonators, and can resolve the less than 1% of Argon as well as the minuscule amounts moisture, CO2, etc.
