How to Check the Manufacturing Year of Car Tires?
2 Answers
The method to check the manufacturing year of car tires is as follows: Look on the sidewall of the tire. The last four digits following the DOT marking indicate the production date, formatted as AABB. The first two digits represent the week of the year, while the last two digits represent the year. Tires are mounted on metal rims and serve the following purposes: 1. Supporting the entire weight of the vehicle and bearing the vehicle's load; 2. Protecting automotive components from severe vibrations and premature damage; 3. Transmitting traction and braking torque, ensuring good adhesion between the wheels and the road surface to enhance the vehicle's power, braking, and off-road capabilities.
I remember when I last changed my tires, I found it quite easy to check the tire's manufacturing year. Just look for the DOT mark on the sidewall of the tire, followed by a series of numbers. The last four digits indicate the production year—for example, 0521 means the 5th week of 2021. Why is this important? Because tires age over time, and as the rubber hardens, the grip decreases, making them more prone to skidding or blowing out at high speeds. So, I recommend checking them every six months for cracks or wear. When buying new tires, it's best to choose ones manufactured within the last 3 years to ensure driving safety and save money by avoiding unexpected repairs. Also, always keep an eye on tire pressure to avoid affecting handling and fuel efficiency. These are all small tips I've picked up from maintaining my own car.
