Tires are dated because they age when exposed to air (Oxygen), regardless of miles, tread depth, or damage. The 3rd 4-digit group in the DOT number is the Julian week (00-52) and the last 2 digits of the year that the tire was manufactured. 6-year-old tires are risky at highway speeds; 8-year-old tires are dangerous at road speeds.
