How to Know the Production Date of a Tire?

[CodyLynn]

The production date of a car tire is generally represented by a four-digit number, where the first two digits indicate the production week and the last two digits represent the production year. Here is the relevant information: 1. The production date of a car tire is part of a series of alphanumeric characters starting with DOT, which stands for U.S. Department of Transportation certification. 2. The following numbers and letters represent the tire's origin information and factory code. 3. The last four digits indicate the production date. 4. Generally, the maximum speed on highways is controlled at 120 km/h, but as tires are continuously used, their load-bearing capacity weakens, and changes in road temperature can also reduce the maximum speed rating. Therefore, manufacturers equip tires with a speed rating several levels higher than the 120 km/h limit to ensure vehicle safety.
