난이도 & 준비물

증상

Unused tires harden and deteriorate quickly in harsh desert climates. When I shop for tires I want to make sure I get ones that are as fresh as possible from the factory without trusting the sales representatives too much. Is it possible to tell when a tire was made just by looking at it?

처리 내용

Most legislations require tire manufacturers to list the week and year of manufacture as a 4-digit code on the sidewall. In the example picture, the last four digits of the tire identification number (5107) refer to the week and year of manufacture ( WWYY format). This means that the tire in the image was manufactured in Week 51 of 2007 (mid-December).
