How Long Does a Tire Qualify as Stock Inventory?

[ChristianDella]

Tires that have been in stock for 1 year are considered stock inventory tires. The shelf life of tires is generally 3 to 5 years. Common tires, such as all-season tires and economy tires, typically have a working lifespan exceeding 50,000 kilometers. Most ordinary users rarely reach 50,000 kilometers within two years. However, for high-performance tires, many have a lifespan of only 30,000 or even 20,000 kilometers, so stock inventory tires that have been stored for a full year should be carefully considered. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are usually installed on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance.
