I understand that they all give you a cold setting but they also dont give a specific setting as the vehicle is going to be driven in a wide range of climates. Also it is my understanding that your tires will settle in and hold a specific temperature just like your cooling system but that temperature will vary with ambient air temperature like you stated which is why you would have to adjust your tire pressures according to the season giving you a more consistent contact patch over the year.
I was under the impression that the tires will reach a steady temperature after driving for X amount to time. If they do then your cold setting would change to try and maintain the hot setting. So if your tires reach 150* for instance and dont vary greatly from that number no matter how far you drive. Then when you set your tires at 30psi on a 90* day you will reach a final pressure of ~36psi, so it was my understanding that if you put 30psi in your tires when its 90* the final pressure reading would be different than if you put 30 psi in your tires when its 30* outside.
But my understanding of this could be completely wrong

Good day.
