I was told to park it with my tires on several layers of thick cardboard to avoid flat spots. I didn't think it would work but I tried it last winter and it seemed to help!
If you aren't going do drive it for a while dollies are a great way to go: http://www.northerntool.com/shop/too...5530_200365530
No flat spots and you can move the car if you need to.
