The frequency of tire replacement depends on factors such as the tire's age, wear and aging degree, and daily driving scenarios. Typically, the lifespan of a tire can reach 3-5 years or 60,000 to 80,000 kilometers.
Tires, being one of the essential components of a car, come in direct contact with the road, making their safety paramount. First, when purchasing tires, one can determine their suitability by checking the production date on the tire. If the production date is too old, even if the tire is new, it's not recommended for purchase.
For instance, in the depicted example, the two numbers on the right of the four-digit code represent the year, while the two numbers on the left indicate the week of that year the tire was manufactured.
Furthermore, all tires come with wear indicators. On the tire's sidewall pattern, one can locate an arrow in the shape of a triangle. Inside the tread groove, there's also a marker protruding by 1.6 millimeters (the regulated minimum groove depth). When the tire wear reaches this marker, it's time to replace the tire.
