Where to Check the Manufacturing Date of Tires?
2 Answers
The manufacturing date of tires is marked on the outer side of the tire. Without needing to flip the tire, there is a set of numbers on the sidewall of the tire. The last four digits of this set of numbers provide information about the production date, consisting of four digits 'aabb'. The first two digits 'aa' indicate the week of the year, and the last two digits 'bb' indicate the year. The 11-digit number and letters immediately following the 'DOT' letters on the tire sidewall represent the tire's identification number or serial number. The last four digits of the serial number indicate the production date of the tire. The tire production date code format is as follows: the first two digits represent the production week, and the last two digits represent the production year. For example, if the last four digits of 'DOT' are '4117', it means the tire was produced in the 41st week of 2017.
Finding the tire manufacturing date is quite simple—it's located on the tire's sidewall, usually near the rim area. Just crouch down and look for a string of alphanumeric characters. Start with the line beginning with 'DOT.' The last four digits are crucial: the first two indicate the week of the year, and the last two represent the year. For example, '2521' means the tire was produced in the 25th week of 2021. As someone who enjoys tinkering with cars, I always check this when buying used vehicles—older tires with aged rubber lose grip and are prone to blowouts, which is especially dangerous on highways. I recommend checking the date every six months while washing your car. If the tires are over five years old, replace them promptly. Proper maintenance can save you a lot on repairs while ensuring safety and peace of mind.
