Why Are There Cracks in the Middle Groove of the Tire?

[RyderRose]

Tire grooves develop cracks due to the following reasons: 1. Traumatic cracking: This type of cracking usually occurs irregularly in terms of location, shape, and size, caused by collisions, compression, or scraping against foreign objects while driving. 2. Aging cracks: These cracks typically appear in the later stages of tire usage, often found on the tire shoulder or lower sidewall, and sometimes visible at the bottom of the tread grooves. Additional information: Tires are one of the essential components of a vehicle, with main functions including: 1. Supporting the entire weight of the vehicle and bearing the load; transmitting traction and braking torque to ensure adhesion between the wheels and the road surface. 2. Reducing and absorbing vibrations and impacts during driving, preventing excessive vibrations and premature damage to vehicle components, adapting to high-speed performance, reducing driving noise, and ensuring safety, handling stability, comfort, and fuel efficiency.
