temperatures & driving
I drive at all temps with no problems. I did learn to drive in Alaska so I guess I have the experience. I've ridden motorcycles on the street in below zero temps so driving my GT in sub-50 temps is no problem. Like DBK says - less aggressiveness is the answer.
Softer compound tires will warm up quicker .ie Hoosiers .Also bumping up tire pressures 5-lbs will make the tires heat up faster .Be careful not to over inflate .
The tires themselves are the most important. Once a tire has too many heat cycles, it will not have grip. Does not matter how much tread is left. This of course only affects high performance tires, but that should be what is on this car. Of course, high performance tires are often called "summer" tires for a reason.
