How Long Does a Tire Qualify as Stock Inventory?

[LeFrank]

Normal tires are considered stock inventory if they exceed one year. Additional details about tires are as follows: 1. Tires are rubber products, and their storage is affected by humidity and temperature. Rubber is highly sensitive to environmental temperature and humidity, and prolonged storage can lead to aging. 2. Various chemical substances inside the tire require time to be released and stabilized. Only after stabilization can the tire's wear resistance reach an ideal state, allowing for longer use and mileage. 3. Tires that have been in storage for three years are considered expired. The rubber in these tires has aged, significantly reducing comfort and making them prone to cracking. Their heat dissipation deteriorates, greatly impacting both acceleration and braking. High-speed driving with such tires also increases the risk of blowouts, seriously endangering the safety and property of the vehicle owner.
