Are the Manufacturing Dates of All 4 Tires on a New Car the Same?

[EmiliaMarie]

The manufacturing dates of the four tires on a new car may vary, which is normal, but the production year of all four tires should be the same. How to Check Tire Manufacturing Date: All tires have a manufacturing date, which can be found on the outer sidewall of the tire. It usually appears in a format like DOTLFLMD79H0816. The last four digits after DOT indicate the production date: the first two digits represent the week of the year, and the last two digits represent the year. For example, 0816 means the tire was produced in the 8th week of 2016. Things to Note When Purchasing Tires: When buying tires, choose those with a recent manufacturing date, ideally within one year. This is because the main material of tires is rubber, which naturally ages over time, becoming prone to cracking and significantly losing its heat dissipation properties. This leads to poor driving comfort, slower acceleration, and potential loss of control during braking due to reduced grip.
