What is the valid shelf life of car tires?

Car tires have a valid shelf life of 5 years or 60,000 to 80,000 kilometers, depending on local road conditions and specific usage circumstances. The main component of tires is rubber, which has a shelf life, so tires naturally have one as well. Fresh rubber exhibits better performance in various aspects, hence newly manufactured tires also perform better. Tires are circular elastic rubber products mounted on vehicles or machinery to roll on the ground. They are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high/low temperature effects during operation, thus requiring high load-bearing capacity, traction performance, and cushioning properties.
I personally believe that the effective shelf life of tires is typically 6 to 10 years, but what really matters is focusing on safety because aged tires are too prone to causing accidents. I've seen many cases where tires, after sitting for too long, become hardened and cracked, leading to blowouts as soon as they hit the road, especially in rainy weather or at high speeds. Manufacturers recommend replacing them after 6 years, even if the tread looks fine, because rubber naturally degrades over time. Regular inspections are crucial—like me checking the tire sidewalls for cracks every week and using a tire pressure gauge to maintain the correct pressure. Storage conditions also make a big difference; if the car isn't driven for long periods, avoid exposing the tires to direct sunlight and park in a shaded area if possible. In short, safety comes first—after 6 years, it's time for a thorough check or replacement.
I drive my car a lot, commuting dozens of kilometers every day, so the tires wear out pretty quickly, making the lifespan shorter for me. Generally, I find the grip deteriorates after about 5 years and they need replacing. I often hear people say tires can last 10 years, but actual driving habits can shorten their lifespan, like frequent hard braking or driving on rough roads, which accelerates tire aging. For high-mileage vehicles, I recommend checking the tires every 50,000 kilometers—once they're worn down to the tread wear indicators, it's time to replace them. When the car was new, I always paid attention to rotating the tires, swapping the front and rear tires to ensure even wear and extend their life a bit. Temperature also plays a role; tires age slower in winter, but overall, you still need to be careful. I wouldn’t risk driving on tires older than 6 years.
