Tyres go bad through the vehicle’s weight, so either raise the vehicle enough so they don’t touch the ground, or remove wheels and put it on stands.
Once you make sure the car is secure release the handbrake so it’s not engaged for a long period to prevent it from fusing.
Clean thoroughly inside and out to make sure dirt doesn’t adhere to paint or seats, that no food is left inside the cabin that can go bad and smells that can embed themselves in the seat foam etc.
Cover with a car cover to protect seals, paint, seats from the elements.
