Do tires need to be replaced after 7 years?

[McJaxson]

Tires generally have a lifespan of 3-5 years. If tires have been used for more than 7 years, they have exceeded their service life, which can significantly compromise safety performance and must be replaced. Related information: 1. Considerations: Mileage is not the sole factor in determining whether tires need replacement; the age of the tires is also a critical factor. Tires are rubber products, and over time, the rubber will deteriorate. Even if the tread appears relatively intact, tires that have exceeded their recommended lifespan should be replaced because aged tires are highly prone to blowouts. 2. Additional information: Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are typically installed on metal rims, supporting the vehicle body, absorbing external shocks, ensuring contact with the road surface, and maintaining the vehicle's driving performance.
