There are alot of tires sitting around out there between the manufacturer, the warehouse/wholesaler, and retailer. Sitting somewhere dark and cool with mold release on them shouldnt be a worry. It is once they get heat cycled a couple times that the rubber really degrades.

Bike tires have a good shelf life too, until they get heat cycled. Then the traction falls off quickly and the dry rott begins in earnest.
