How to Check the Manufacturing Date of Car Tires?
3 Answers
Tire manufacturing date can be checked through the markings on the tire sidewall, usually in the format of DOTXXXXX3115. The last four digits after DOT indicate the manufacturing date of the tire. The first two digits represent the week of the year, and the last two digits represent the year. Here are the specific methods to check the tire manufacturing date: 1. There is a set of numbers on the tire wall, and the last four digits of this marking provide the production date information. 2. It consists of four digits AABB, where the first two digits AA indicate the week of the year, and the last two digits BB indicate the year.
Back when I drove a used car, I learned how to check the manufacturing date of tires, which is really useful. Look at the sidewall of the tire where some letters and numbers are printed, and focus on the last four-digit combination. For example, if you see '2319', it means the tire was manufactured in the 23rd week of 2019. The numbers are usually preceded by the letters 'DOT', so make sure you don’t look at the wrong spot. Aged tires develop cracks, lose grip, and are more prone to blowouts, so I regularly check the manufacturing date. I try not to use tires older than six years, and when buying new ones, I always check the date first for safety.
I work in car maintenance and often get asked about this. Just look at the outer ring of the tire where there's a row of codes printed. Find the part that starts with DOT—the last four digits are the date code. The first two digits represent the week of the year, and the last two are the year. For example, 0522 means the 5th week of 2022. Remember, when interpreting, make sure it's not mixed with other markings. If it's a bit blurry in some places, wipe off the dust. Old tires become brittle, especially in winter, making them prone to issues. It's recommended to check the date during every maintenance to ensure they're within the safe period.
