I would guess that if they're stored in a cool dark place, and, preferably, kept wrapped somehow, they should be good for ten years or so (though possibly less for gumwalls). You need to keep them away from UV light, ozone, and stuff like fumes from a poorly vented heater. (Also, any sort of petroleum fumes would be bad, so a garage is not ideaideal.)

Also try to store them in such a way that they won't be distorted too badly (though perfectly flat is not necessary). Wrapping (spiral plastic wrap, eg) helps keep the nasty stuff away, and helps keep them from getting distorted.
