Hey man,
Yes, I usually overinflate my PS4S tires up to 42 PSI. I also roll the car out of the stall after a few weeks and drive within the garage. I have the Anti-gravity Lithium Ion lightweight battery so it holds charge very well and it has an internal battery management system to ensure the battery does not drain (and a built in jump-start) so it has never run out of charge even when the car sits for several weeks. Still, I disconnected the battery to make sure it does not have an impact on the battery life. Sta-Bil fuel stabilizer is another good thing to have as it removes moisture from the fuel lines etc. Let me know if that answers your question.
