What Causes Tire Aging and Cracking?
1 Answers
Tire aging and cracking can be attributed to the following reasons: 1. Traumatic cracking: This type of cracking generally occurs without any regularity in terms of location, shape, or size, and is caused by collisions, compression, or scraping against foreign objects while driving. Some cracks only appear on the surface of the rubber, while others may damage the tire's carcass cords. In severe cases, this can lead to instant tire deflation. If the crack extends to the carcass cords or even causes cord damage, it poses a safety hazard and must be replaced as soon as possible. 2. Aging cracks: These are commonly found on the tire shoulder or lower sidewall areas, and sometimes at the bottom of the tread grooves. This is a natural change in the tire rubber due to long-term flexing and heat generation. Prolonged driving with low tire pressure can accelerate this process, but it usually does not affect the tire's service life or safety performance, and generally does not require early replacement.
