Interesting question. Was wondering this myself, since RH (relative
humidity) typically runs between 20 - 30% where my car is stored. In
summertime, it's goes down to 17 - 22%. Here's one thing I found:
http://www.dry-it-out.com/car-storage-faq Apparently optimum car
storage humidity is 40 - 60%? If that's the case then all the rubber
on my car should have crumbled into dust by now. It's been in this
environmentsince 2007 or so. So far, my rubber is holding up fine.
Even my 10-year old TA radials that are stored inflated in the same
environment do not yet show any deterioration. Maybe it takes a while
for a dry climate to take it's toll but so far I can't see anything
rotting from dryness. I do keep all the vinyl and rubber trim
protected with Vinylex. All engine rubber I don't touch. Probably
should keep an eye out though...

Rubber
hoses? I imagine that a certain amount of humidity keeps things
