Yes. It is pereferable to store on jack stands and remove the wheels. This prevents electrolytic corrosion between dissimilar metals....ie Aluminum wheel and Steel hub/cast iron rotor hub face.
However, IF your lift is hydraulic without a mechanical locking mechanism, this may not be good for the seals in the lift pump. The lift seals were not designed to carry a continuous load over a long period of time. You should always use a mechanical block/locking mechanism to support the load, such as jack stands, and release the hydraulic pressure. This applies to lifts as well as jacks.
Storage in a heated garage with a dehumidifier is preferable instead of an unheated garage. IF the car is stored outside, at least a carport is desirable AND you must use a car cover and keep excess snow off the car regardless.
(Snow if left packed will crack paint & SMC. Snow will then turn to ice and melting ice will slide off and scratch paint)
Some other things to consider:
1. Change oil BEFORE storage
2. Change oil AFTER storage
3. Fill gas tank to FULL and add Stabil
4. Place dessicant packs in trunk and passenger area
5. Hook up a battery tender
6. Wash & Wax exterior,
7. Armor All interior
8. Car cover
9. Remove & store wheels/tires, on side, in a cool, dark area with stable temperature and humidity, above freezing, (a basement is preferable instead of an unheated garage). They can be stacked, no more than 4 high, with a cardboard disc between. Store at 30 ps1 inflation pressure.
