I think you all need to specify what tires you have on which will make this thread more beneficial.
im running michelin pilot sports a/s and when cold its 39 and when at ideal running temp its 42. Today was a hot day and my tires got up to 46psi so i had to release some pressure earlier.

All you need is to follow the placard on driver's side entrance for correct "cold" tire pressure value. No need to worry about warm, hot, or average tire pressure. Tire brands don't matter either. Simple as that.

You're wrong. I've seen plenty of cars with that sticker having more than one tire size and different pressures for each. If what you're saying is correct, then why is the thin temporary spare have a recommended tire pressure of 60 psi?

Gezus. Now that's just stupid. I don't even know how to respond. The tire has no idea of the type or weight of the vehicle. Hence the sticker. And fyi, the sticker does have the temporary tire psi called out specifically.

There are vehicles that come in different engine/drivetrain configurations, and depending on how the vehicle is equipped will change the tire pressure, even the pressure from front to rear in some cases.
It just so happens that the 3IS, no matter the engine or wheel/tire configuration, the recommended pressure is 36PSI all around.
Some owners manuals even recommend increasing the tire pressure by a specific amount if you will be driving faster that a specific speed (i.e if you are consistently driving over 160 kmph, increase the tire pressure by 5 PSI)
