Where to Find the Tire Date?
2 Answers
Tire dates can be found by checking the production batch number on the outer edge of the tire. The production batch number is a combination of numbers and letters indicating the manufacturing month, year, and quantity. Taking 3907 as an example, the tire's production date is the 39th week of 2007, or the latter half of September 2007. The functions of tires are: 1. Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions; 2. Working together with the car suspension to cushion the impact during driving and dampen the resulting vibrations; 3. Preventing severe vibrations and premature damage to car components, adapting to the high-speed performance of the vehicle and reducing driving noise; 4. Transmitting traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the car's power, braking, and passability.
I've been driving for over a decade and changed many tires. Each time, I remind myself to check the tire's production date. It's most visible on the tire sidewall—look for that oval-shaped mark with 'DOT' followed by a series of numbers and letters. Pay special attention to the last four digits, like '2319,' which means the tire was produced in the 23rd week of 2019. Why is this date important? Tires that are too old can become brittle and prone to blowouts at high speeds, which is extremely dangerous. I once had a close call on the highway because I didn’t replace my tires in time—they had aged badly. So, I advise car owners to take a quick look at the tire date during routine maintenance, not just checking the air pressure. This habit can save a lot of trouble, extend tire life, and prioritize safety. Nowadays, when I replace tires, I always prioritize newer production dates—never skimp on small details to save money.
