Tire age

Tires degrade over time, even when they are not being used. It is recommended that tires generally be replaced after 6 years of normal service. Heat caused by hot climates, frequent high loading conditions or Ultra Violet (U.V.) exposure can accelerate the aging process.
The temporary spare1 should also be replaced at 6-year intervals, even if it has never been used.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
