The summary I am taking out of this is driving below 45 to 50 degrees = caution, below 40 degrees = warning, below 35 degrees = danger. Again, even below 35 the car handles consistently and predictably, but at any of these temperatures, the margin for error goes away. Any aggressive maneuver in steering or braking may not get the desired results.

BTW, this was focused on temp, not pressure, but good info on effects of pressure is certainly not unwelcome.
Every tire is different and their characteristics under varying temperatures are different as well. You would need to know how your specific tire reacts to road temps.

Although you may have intended to only address temperature, your experience was no doubt effected by both temperature and the pressure change due to altitude so both should be considered.
