How many years can tires be used?

Car tires have a service life of 5 years or 60,000-80,000 kilometers. More knowledge about car tires is as follows: 1. Tires are circular elastic rubber products assembled on various vehicles or machinery that roll on the ground. 2. Tires are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, achieving contact with the road surface, and ensuring the vehicle's driving performance. 3. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.
From my driving experience, there is no strict standard for tire usage years, but it is generally recommended not to exceed 6 years. This depends on multiple factors: the tire itself has a DOT code indicating the production date, such as the four-digit number on the sidewall representing the week and year. The actual lifespan also depends on tread wear—if it's below 1.6 mm in depth, it's time for a replacement. Usage frequency also matters—if you frequently drive long distances or on rough roads, aging may occur in as little as 3 years. I've encountered cases where tires cracked due to improper storage in garages, so even with low mileage, regular checks are necessary over time. Safety comes first; having a technician regularly measure wear can prevent blowout risks. Additionally, seasonal changes have a significant impact—summer heat accelerates rubber aging, while winter cold makes tires brittle. In short, don’t just focus on the age; annual self-checks of tire pressure and cracks are key for peace of mind while driving.
