You're probably going to be in the 'maybe' zone for storing the tires warmly. Chances are you'll be OK with them in the garage & on the car ... but I wouldn't say you're being obsessive by removing them & storing inside either.
In any case, I'm moving this discussion to the general ZL1 forum because this topic probably affects more Americans than it does Canadians.
Note, if I've gotten any facts wrong in the above, just ignore any points I made with them
