How to Check the Manufacturing Date of a Car Tire?
2 Answers
Car tire manufacturing dates are located on the sidewall of the tire, specifically in the DOT (Department of Transportation) code followed by a series of numbers. The last four digits of this code (enclosed in an oval) indicate the production date. The last two digits represent the year of manufacture, while the first two digits indicate the week of that year when the tire was produced. Here is a brief introduction to car tires: Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the car's suspension system, they help absorb shocks during driving, ensuring good ride comfort and smoothness. They also provide excellent road grip, enhance traction, braking, and off-road capability, and bear the vehicle's weight.
I've been driving for twenty years, and the tire manufacturing date is quite important. It's usually marked on the sidewall of the tire within an oval or square, printed with four digits, such as '1823' indicating the 18th week of 2023. This code is generally located near the rim, following the DOT marking. Tire rubber ages, and after five years, it tends to harden and crack, affecting braking and handling. Once, my friend forgot to check, and an old tire blew out on the highway, nearly causing an accident. Now, with my family's car, I take a quick glance at the date during seasonal maintenance and note it in the log. When buying new tires, it's better to choose those with a recent manufacturing date; those over a year old may have been in stock for too long and could be of poorer quality. Paying attention to this in daily driving can save both peace of mind and repair costs.
