For winter storage no need to remove the wheels/tires and it is not advised one raise the car unless one can lift the car via its tires/wheels which leaves the suspension slightly compressed which is considered best for long term storage.
Just do what the factory does. Inflate the tires to something close to their max recommended pressure which is IIRC 45psi. This is the tire pressure the tires leave the factory with and is suited for storage. New cars often sit some time and this higher pressure helps them resist flat spotting.
Obviously when it is time to resume using the car adjust the tire pressures to what the factory calls for, probably 32psi.
