Tire Age / DOT Date Checker

DOT “Born-On” Date Decoder

Enter the DOT code from your sidewall. We’ll locate the four-digit date (WWYY = week/year), calculate age, and advise if the tire is nearing the 6–10 year replacement window.

Please enter a valid 4-digit date code (week 01–53, year 00–99). Pre-2000 3-digit codes are supported but considered end-of-life.
Where to look: The full DOT code appears on one sidewall only. The last 4 digits are the date — for example, 2319 means week 23 of 2019.

Important: Rubber degrades with time, heat, and storage conditions. Many manufacturers suggest inspection around 6 years and replacement by 10 years, even if tread remains. Always follow manufacturer guidance and your vehicle placard.

Key Takeaways

  • Find the last 4 digits. They show week and year the tire was made (WWYY).
  • Time matters. Many makers advise inspection near 6 years and replacement by 10 years, regardless of tread.
  • Storage & heat accelerate aging. Sun, heat, and low inflation shorten tire life.
  • Pre-2000 codes. A 3-digit code indicates 1990s or earlier — these are past service life.
