What is the valid shelf life of car tires?

[LaylaLynn]

Car tires have a valid shelf life of 5 years or 60,000 to 80,000 kilometers, depending on local road conditions and specific usage circumstances. The main component of tires is rubber, which has a shelf life, so tires naturally have one as well. Fresh rubber exhibits better performance in various aspects, hence newly manufactured tires also perform better. Tires are circular elastic rubber products mounted on vehicles or machinery to roll on the ground. They are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high/low temperature effects during operation, thus requiring high load-bearing capacity, traction performance, and cushioning properties.
