Tires that sit will crack sooner than those in use, due to the nature of synthetic rubber. Each crack exposes the internal structure of the tire to all the elements they're not designed to deal with.

That single molecule in the form of a tire has been fractured and the framework is no longer protected. The edge of every crack acts like one of those bars for tearing off paper -- every flex is trying to break a cord.

Short form: Those things have been may-pops for years.
