Over inflate, prevents flat spots, and just don't let the car move at all when below freezing.
This Spring mine will be changed due to wear, not damage.

Nothing to worry about! Tires will be fine.

Though I would worry about summer tires in the bare cold just sitting there. I swap wheels and tires each season and my summers stay in the garage where I have a little heat and it's generally 50 degrees at worst.

Thanks for all of the responses - I checked in with a Goodyear tire engineer ( recent autocross national champ), and everyone agrees, that they should be just fine, as long as the car isn't moved when it's cold. I will also overinflate as recommended here.

Thanks again,
