What is the optimal time to use tires after production?
2 Answers
Tires are best used six months after production. Under normal conditions, it takes about six months for the rubber molecules in tires to gradually stabilize, making them more elastic and wear-resistant. After two years, the rubber properties begin to degrade, and cracks are more likely to appear after installation and use. If stored for three to four years or longer, this issue becomes even more pronounced, and such tires are not recommended for purchase or installation. Tires are circular elastic rubber products mounted on various vehicles or machinery, typically fitted on metal rims. They support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance.
I've been driving for many years, and the recommended optimal usage period for tires after leaving the factory is generally within 5 years, as rubber aging can affect safety performance. Even if the tires haven't been used much, prolonged storage can lead to cracks, increasing the risk of blowouts. In daily life, UV rays, high temperatures, and humidity can accelerate aging, so it's essential to check the DOT code on the sidewall when purchasing. For example, '3221' indicates the tire was produced in the 32nd week of 2021. It's best to choose tires within two years of production and store them in a cool, dry place. I remember a friend who had an accident using expired tires, which came at a high cost. Regularly checking the tire's hardness and for cracks is crucial.
