Generally performance tires in the 200tw range should be allowed to return to ambient temps for about a day at more than 40-45*F, after sitting in weather well below freezing (like under 20ish*F). I'll see if I can get a link from a manufacturer for you. If you don't do this the tire won't be totally ruined usually, but it will be detrimental to the tires peak performance.
EDIT: tirerack link
"
Extreme Performance Summer tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle." -Falken Tire
