Determining a tire’s production date is accomplished by examining the Tire Identification Number (TIN), also known as the DOT code, located on the tire’s sidewall. The final four digits of this code indicate the week and year of manufacture. For instance, a code ending in “2223” signifies that the tire was manufactured in the 22nd week of 2023.
Knowing a tire’s age is crucial for safety and performance. Rubber compounds degrade over time, regardless of usage, leading to reduced grip and increased risk of failure. Identifying the date helps consumers make informed decisions about tire replacement, ensuring vehicle safety and optimal handling characteristics. This practice has become increasingly important as vehicles are kept in service longer and tires may sit unused for extended periods.
