What Causes Car Tire Cracking?

[ElianaRose]

Tire cracking causes: 1. Traumatic cracking: This type of cracking usually occurs irregularly in terms of location, shape, and size, resulting from collisions, compression, or scraping against foreign objects while driving. Some cracks only appear on the rubber surface, while others may damage the tire body cords, with severe cases leading to instant tire deflation. 2. Aging cracks: These cracks typically appear in the later stages of tire use, mostly on the tire shoulder or lower sidewall, and sometimes at the bottom of tread grooves. This phenomenon is a natural change in tire rubber due to long-term flexing and heat generation. Prolonged driving with low tire pressure can accelerate this process, but it generally doesn't affect the tire's service life or safety performance, and usually doesn't require premature replacement.
