I couldn't take it any longer!!! Took the car out of storage....

For those concerned about flatspotting and tire damage due to overinflation, it clearly states in your Owner's Manual, for long term storage to overinflate your tires. For example, it is recommended to overinflate my 2006 987S to 58 PSI.

I've done this now for 4 winters, with excellent results (I also take one step further, and use nitrogen).

I lift the car and turn the wheels a quarter turn once a month. I don't have lot of front to back room where I store it so moving it to rotate the tires really isn't an option. Also, it's -29C here right now - you wanna try rolling a car that's been sitting at that temperature for a while - you'll think it's been welded to the floor.
