The evidence is clear: tires should have an expiration date. Older tires are substantially more likely to fail than newer ones. This is because tires are made mostly of rubber, and rubber degrades with age. Sunlight, heat, ice, and general wear and tear can accelerate the breakdown of a tire. Once a tire begins to break down, it becomes more likely to fail in the form of a tread separation—often at highway speeds, when the failure is most likely to cause catastrophic injuries or death.

For most tires, this expiration date should be six years from the date of manufacture. Tires age dangerously because of a chemical process commonly referred to as oxidation, which simply means that as the tire components are exposed to oxygen, the oxygen particles cause the flexible components of a tire to harden and become brittle. Over time, the tire will simply fall apart under normal stress, just like an old rubber band.

Because this process occurs naturally, it does not matter if a tire is being used, stored as a spare, or simply waiting on a store shelf for an unsuspecting consumer. In , the average tread life of a passenger car tire was approximately 24, miles.
