How Many Weeks Represent Which Month for Tires?

[McJoy]

Tire production dates are typically indicated on the tire sidewall with a four-digit code. The first two digits represent the week of production within the year, while the last two digits indicate the production year. To estimate the production month, divide the week number by 4. For example, code 0813 means the 8th week of 2013. Dividing 8 by 4 gives 2, indicating production around late February 2013. Below is relevant information about tires: 1. Overview: Tires are circular elastic rubber products mounted on vehicles or machinery for ground contact and rolling. 2. Functions: Installed on metal rims, they support vehicle weight, absorb external shocks, maintain road contact, and ensure driving performance. Operating under complex and demanding conditions, tires endure various deformations, loads, forces, and extreme temperatures during use. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption. Additionally, they require excellent wear resistance, flexibility, along with low rolling resistance and heat generation.
