I can definitely feel this. But like you said it goes away fairly quickly with driving.

I think there are two kinds of flat spots, one which is the simple creasing of the rubber from the car sitting on them, the other which involves some kind of thermal distortion. This later kind is basically impossible to get in street driving (involves putting a 200 degree tire on cold concrete and leaving it there as the rubber cools), but it is the kind which the "Tire Cradle" product has the "measurable research" on. Besides which the Tire Cradle is ridiculously priced.

I was going to go with some product like the Tire Cradle for winter storage, but after I learned more I decided to hedge my bets and just store the car with 50 psi in each tire. I left it up to 4 weeks between drives, and never had any issues except for the usual initial vibration like you describe.
