Hanging the bike from two hooks in the ceiling spaced apart the same distance as the axles puts the least force on the rims. Hooks closer together or further apart increase the force. Probably the worst typical case is hanging the bike vertically from one hook in a wall. The force placed on the rim can be several times the weight of the bike.
Actually the force cannot be greater than the weight of the bike. The pressure, however, can be elevated due to the small contact area of the rim on the hook. No matter, the rims are plenty strong enough to withstand such treatment. Think about the pressure exerted by a single spoke nipple on the very tiny surface area around a spoke hole. 120 kgF over a small fraction of a square inch is far more pressure than exerted by an 8 kg bike on the area contacted by the hook. Two hooks would divide the force about in half which would be an improvement, but not a very significant one.
