How to Check the Manufacturing Year of a Tire?
2 Answers
Locate the DOT marking on the tire sidewall, and the last four digits following DOT indicate the manufacturing date of the tire. The first two digits represent the week of the year, while the last two digits denote the year of production. Here is some relevant information about tires: 1. Primary Material of Tires: The main material of tires is rubber, which has the characteristic of aging over time or after prolonged storage. This aging process leads to significant changes in the tire's physical properties, such as hardness and wear resistance. Continued use of aged tires may mildly affect vehicle performance or, in severe cases, result in a tire blowout. 2. Lifespan of Tires: Generally, all-season or economy tires have a lifespan of 3-5 years, with a mileage of approximately 50,000 kilometers. Under normal circumstances, tires are sufficiently usable for one year post-manufacture. However, for high-performance tires, the lifespan is only about 20,000 to 30,000 kilometers. If the price is reduced, purchasing them might also be a consideration.
Checking the tire's production year is actually quite easy. As someone who's been driving for years, I always pay special attention when changing tires. You can usually find the DOT code on the tire sidewall, with 4 digits at the end - for example "2319" means the tire was produced in the 23rd week of 2019. Don't get it wrong, the first two digits represent the week number and the last two digits indicate the year. I recommend choosing tires with recent production dates when purchasing, as aging tires quickly lose grip. Additionally, rubber hardens over time, so even if the tires haven't been used much, you should still check the date - consider replacing them after five years. During regular maintenance, take a look at tire wear and cracks too, especially before long trips. Safety comes first - this habit can save you a lot of trouble and money.
