Remember that tires are perishable goods. As of 2000, the manufacturing week and year will be
indicated with 4 digits (e.g. 1502 means that the tire illustrated was manufactured during week 15 of
2002).
Tire age
Tires degrade over time, even when they are not being used, which can affect their reliability and
roadholding characteristics. Therefore, all tires older than 6 years (including the spare tire and winter
tires) should be inspected by a qualified technician, regardless of appearance or mileage. Heat caused by
hot climates or frequent high loading conditions can accelerate the aging process.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration above).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
