I like this line:
"Tire dealers testifying at the hearing agreed that heat, punctures and poor handling accelerate the degradation of a tire, but insisted that with proper storage a tire can last many years.
"A 10-year-old tire can be better than a newer tire that's sat out in the sun," said Ralph Schissler, president of Atlantic Tire in Baltimore."
Don't have a garage? Just remove your tires and store them each time between uses...
I have to agree that the part about informing the buyers that their new tires they just bought are already three years old is a good idea.
