What is the shelf life of new car tires?

[BrandonLee]

New car tires have a shelf life of between 2 to 3 years, as the main raw material of car tires is rubber, which has the characteristic of aging over time, leading to a decline in tire performance. Generally, the aging process of tires occurs between 3 to 5 years. When purchasing tires, it is advisable to choose tires with a production date as recent as possible, preferably within 1 year. Tires that have exceeded 3 years should not be purchased. Tire maintenance: 1. Regularly check tire pressure, as it is a crucial factor affecting tire lifespan—avoid overinflation or underinflation and inflate according to the vehicle's indicated tire pressure; 2. Frequently remove debris from tire treads; 3. Control speed reasonably; 4. Regularly inspect tire wear conditions.
