Is it normal for car tires to have small cracks?

[StManuel]

Tire cracks should be evaluated based on the actual situation. Factors such as usage duration, driving conditions, road surface conditions, natural aging or cracking of the tire, and the tire's own quality should be considered separately. Professional inspection and testing should be conducted before deciding whether to replace the tire. The following is an introduction to tires: 1. The main functions of tires include dry grip, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet grip, load capacity, handling performance, average wear, and mileage. 2. The cross-sectional structure of a tire can be roughly divided into four parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread mainly contacts the ground, the shoulder and sidewall provide support, and the bead contacts the wheel rim to provide sealing.
