LOL, I understand it's good to put a little Ar, CO2 and H2O in that mixture.

I try to run factory spec but once the tire warms up tire pressure goes up signficantly during summer months. Took a long drive to Flagstaff last Sept from the Bay Area and had to drive thourgh Mojave desrt. Saw my tire pressure go up as much as 4 psi front and rear. Winter months seems it doesn't go up as much.

Now I run 30 up front and 34 at the rear.
