Usually the date code is on the inside of a mounted tire.
Many "experts" say the shelf life of a tire is 6 years (Ford), but others say you should replace a tire after it is 10 years old (Bridgestone). Others say 5 years if you are in a hot climate and ten years if you are in a cold climate.
All I know is that my SPF was manufactured in 2001, so the tires are at least 7 years old, and will be replaced this winter.
Here is good explanation of date codes
