I know there are posts, but am lazy to search...lol

I just took the car our for a nice drive (05 997S) and then pumped the tires up to approx. 45 psi, put back into the garage and hooked up the Porsche charger and put the cover back on! My question is:

Is approx. 45 psi good enough to prevent flat spots??

There is a squeak sound from the passenger window when I open the door (when to window drops 1/2 and inch)...what can I do about that?? is there some sort of seal conditioner I can use??

Thanks

 

I try to move mine once a month, never had an issues with flat spots by doing this

Is the squeak coming from the window going down or the door?

 

it's coming from the window going up and down.
