How long would you expect a set of car tires to last when stored in the
garage?

By stored I mean dismounted, no rims, no wheels, kept out of sunlight as
best you could.


I don't know what the maximum is, but I've used tires that were over five
years old, driven on tires that were well over 10 years old. and have seen
cars with tires that were 15+ years old. You may get more detailed
information on an automotive newsgroup, especially if one is devoted to
classics or antiques.
