The date code will let you know when tires need to be replaced. The two digits before the year indicate the week of the year that the tires were manufactured.There are 52 weeks in a year, so these two digits range from 01 to 52.
While they were required to provide the same information as today's tires, the week and year the tire was produced was contained in the last three digits.
Tires in hot dry climates have much shorter lives than those in moderate, moist climates.
Still, you want to maximize tire life when buying a new set of rubber.
The rubber on a car tire degrades over time, and tire warranties can be tied to manufacturing dates.
Every tire sold in the United States has a date code stamped on it. If the last two digits are 07, for example, the tire was manufactured in 2007.
