I can recall that many years ago when I was running Pirelli P7,s the Pirelli reps would slash any tyres found unused after 12 months to the day of manufacture. I had this confirmed today. My dealer for high performance tyres said they must be "exercised" and he used the example that if I did a track day and let the car sit idle for 12 mths I would need new tyres as the old tyres would have gone off. They would not have the grip that they had previously. Life may depend on make of tire but the sensible thing to do is put fresh tires on at the last minute. Local dealers here would be happy to give you a set of old tyres for the build as they have to pay to dispose of their used rubber. Regards
