I've been winter parking my cars for 7 years now in cold and warm storage and it does get cold here.

I've never had a problem with flat spotting any of my tires while sitting on concrete over the winter. I just pump up the pressure to the max cold pressure rating on the tire and call it a season. Adjust the pressure to what I run in the spring and it's done and ready to go.
