true, but you'd have to figure out the temperature inside the tire. but if you can figure out the tempurature, be sure to use absolute tempurature (rankine or kelvin). of course, you're assuming you're working with an ideal gas.Macabre said:P1/P2 = T1/T2... however, you can't rely on that, because humidity has a significantly more complicated effect.
You could do what I do...I add, say, 4 or 5 PSI when I get home and there's still some daylight to work with. Then, in the morning before I move the car, I deflate the tires to whatever pressure setting I want. The tires are cold and you can set them perfectly. Just don't overshoot on the deflation!JETninja said:Just wondering....The B5's numbers in the fuel door are based on Cold. I often think of filling them after the long drive home, when the tires are nice and toasty!
