How old is the appropriate production date for tires?

Tires with more recent production dates are preferable, and you should avoid purchasing tires that have been in storage for over three years. As rubber products, tires can age even when not in use for extended periods. Typically, tires installed on a vehicle can last for about four years, so it is recommended that car owners replace their tires every four years. When purchasing tires, always check the production date carefully. Car tires are one of the essential components of a vehicle, directly contacting the road surface and working in conjunction with the suspension system to absorb shocks during driving, ensuring a comfortable ride and smooth operation. Tires also ensure good adhesion between the wheels and the road surface, enhancing the vehicle's traction.
As an ordinary office worker, I'm particularly concerned about driving safety, as the production date of tires directly affects their aging condition. Generally, the code on the tire sidewall, such as 2721, indicates the 27th week of 2021. From a safety perspective, aged tires become brittle and prone to blowouts, especially on highways. I often hear mechanics say that tires should be replaced every 5-6 years even if they show no wear, especially for vehicles parked outdoors exposed to sunlight. It's essential to develop the habit of checking tread depth and sidewall cracks every six months. In hot and humid climates, extra caution is needed as aging accelerates—replace them earlier if necessary. Don't compromise safety to save money by using tires too long; accidents can happen when least expected. I've personally experienced this urgency and now ensure regular tire replacements for my family's safe and worry-free travels.
I usually pay great attention to cost control when driving, and the production date of tires is something to be calculated carefully. By looking at the four-digit number on the tire sidewall, you can know the manufacturing year and week. Economically speaking, tires don't save you money the longer they're used—aging tires increase fuel consumption and wear out faster, leading to higher maintenance costs. I recommend replacing them within about 5 years for better cost-effectiveness. Based on personal experience, if the car is parked in a garage or shaded area where aging is slower, you can stretch it to 6 years; but if you frequently drive long distances, the combined effect of wear and aging means it's better to replace them at 4 years. Check the tread depth—when it's less than 2mm, replace them immediately to balance safety and expenses. Every time I change tires, I choose big brands during promotions, and the money saved outweighs the risk of delay.
