What is the tire temperature that we can run our new car tires down to?

What is the lowest temperature we can run the C7 tires down to (excluding the sport cup 2 on the Z07 packages). I hear 45 degrees and I hear 20 degrees (Feh.). After that they are supposed to start cracking. Anyone know the answer?
