Is a small crack in a car tire serious?

[AutumnDella]

It depends on the depth of the crack. If the steel belts are not damaged, it's generally not a major issue. Below is some relevant information about tires: 1. Main materials of tires: The primary material of tires is rubber. The characteristic of rubber is that it ages over time or after prolonged storage, leading to significant changes in the tire's physical properties such as hardness and wear resistance. If an aged tire continues to be used, it may affect vehicle performance at best or cause a blowout at worst. 2. Tire lifespan: Typically, all-season or economy tires have a lifespan of 3-5 years, with a mileage of around 50,000 kilometers. Under normal conditions, a tire's lifespan of one year after leaving the factory is sufficient for use. However, for high-performance tires, the lifespan is only 20,000-30,000 kilometers. If the price drops, it might also be worth considering purchasing them.
