Where to Find the Manufacturing Date on Car Tires?
2 Answers
The manufacturing date of car tires can be found by locating a series of numbers on the outer sidewall of the tire. The last four digits represent the production date of the tire. The functions of car tires include: 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 impacts during driving and dampen resulting vibrations; 3. Protecting car components from severe vibrations and premature damage, 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 off-road capabilities.
Every time I help friends check cars, I pay special attention to the tire date, and its location is actually quite easy to find. Hidden within the string of letters and numbers on the tire sidewall is a four-digit production week number. For example, 3223 means the tire was produced in the 32nd week of 2023. The first two digits represent the week, and the last two digits represent the year. I remember once discovering that the owner hadn’t changed the tires in four years, and the tread was almost worn out—tire lifespan is typically only five to six years. Even if the tread is deep, rubber aging can affect grip. Now, when selecting a used car, I always check this. Last time, I even saw a new tire that had been in stock for two years, with its surface already cracked. I recommend checking the tire date when you inspect the tire pressure every month—safety is something you can’t afford to be careless about.
