How Long for New Tires to Be Considered Stock?

[MacArya]

New tires that have been stored for over a year can be considered stock tires. In fact, there is a set of numbers on the sidewall of the tire. The last four digits of this set represent the manufacturing date, with the first two digits indicating the week of the year and the last two digits representing the year. By calculating this, you can determine whether the tire is a stock tire. Tires are circular elastic rubber products assembled on various vehicles or machinery to roll on the ground. They are usually mounted on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning capabilities.
