How to Know the Manufacturing Date of a Tire?
2 Answers
To know the manufacturing date of a tire, follow these steps: 1. Locate a set of four numbers on the tire wall; 2. The first two digits represent the week of the year the tire was produced; 3. The last two digits indicate the year of production. Tires are circular elastic rubber products installed on metal rims, designed to support the vehicle body, absorb external shocks, maintain contact with the road, and ensure driving performance. Tire maintenance methods include: 1. Regularly check tire pressure; 2. Remove debris from tire treads; 3. Inspect tire wear and replace them promptly if necessary; 4. Perform tire rotation to ensure even wear across all four tires and prevent excessive wear.
I didn't know how to check the tire manufacturing date before either, until one time when my tire blew out and I realized how important this is. That time on the highway, the tire suddenly bulged, but luckily nothing serious happened. Later, the mechanic told me there's a numerical code on the tire sidewall, and you just need to look for the last four digits. For example, if you see 2321, it means the tire was manufactured in the 23rd week of 2021. Tires deteriorate over time, usually becoming dangerous after six or seven years, as the rubber can crack and cause blowouts. Now, every time I change tires, I check the date myself and even take a photo with my phone to avoid remembering it wrong. It's actually quite simple—just squat down and look at the tire sidewall; if the lighting is poor, use a flashlight to see clearly. This trick can save you a lot of money, preventing you from being overcharged by repair shops when they push for unnecessary new tires.
