Old-timer's suggestions...
Store them in a cool, dark place, away from windows. A rarely-used closet is ideal.
Store them away from furnace, fridge, or anything else with an electric motor. Arcing from an old electric motor creates low-level ozone, which damages rubber, latex, plastic.
Store them partially-inflated, laying flat on a large shelf if possible.
If stored hanging from a hook, rotate them monthly to avoid creasing the tire.
Plastic bags won't protect tires from ozone or humidity - moisture and air will penetrate most plastics bags - but will keep off dust and dirt.
Amour-all (sic), like all chemicals, might accelerate deterioration of latex and silk over the long term.
