I had always thought it was 1 PSI for every 10 degrees temperature difference. However, if that's true, what do they consider the "starting" temperature?
Let's say they refer to 70 degrees as the initial temperature, and your car is supposed to be at 35 PSI when it's 70. I would assume that means that if it's 40 degrees out, you should set your tires to 38 PSI, and if it were 100 degrees out, then set the tires to 32 PSI. So if it's hotter out the PSI goes down, and if it's colder out the PSI goes up.
Am I correct according to my above example?
