What Causes Tire Cracking?

[Melody]

Tire cracking is mainly caused by the following two reasons: 1. Traumatic cracking: This type of cracking usually occurs irregularly in terms of location, shape, and 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 body cords, and in severe cases, can lead to sudden tire deflation. 2. Aging and cracking: This type of cracking generally occurs in the later stages of tire use, commonly seen on the tire shoulders or lower sidewalls, 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. Driving with consistently 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.

Among the most common causes of tire cracking I've encountered over years of driving is aging. Tire rubber hardens and becomes brittle over time, especially when exposed to sunlight or high temperatures—UV rays can bake it until cracks appear. Poor road conditions like potholes or gravel roads also abrade and damage the tire surface. Additionally, I've seen many cases caused by underinflation or overinflation—improper tire pressure leads to deformation that worsens cracking. Regular tire inspections are crucial; neglecting them allows cracks to expand, potentially causing dangerous blowouts. Parking in shaded areas to avoid direct sunlight can extend tire life. Also, don't neglect tire rotation—uneven wear can trigger cracking. I recommend rotating every six months or 10,000 kilometers.

When I first bought a car, I also encountered tire cracks, mainly due to usage habits and external factors. Large fluctuations in tire pressure, such as sudden increases or decreases, can cause uneven stress on the rubber, leading to cracks. Chemicals on the road, like oil stains or de-icing agents, can corrode the tread and accelerate aging. Storage is also crucial—leaving the car parked outdoors for long periods, exposed to wind, rain, and direct UV rays, can cause small cracks to appear in just a few days. I recommend developing a habit of regular inspections; after washing the car, take a moment to check the tread for foreign objects or fine cracks. Addressing issues early can save a lot of money on tire replacements. Also, avoid overloading, as high-speed driving increases tire temperature, which can easily lead to cracks.

Friends who are into mechanical modifications know that tire cracking stems from material and environmental factors. Rubber aging is inevitable, but sudden temperature changes or alternating heat and cold cause it to expand, contract, and develop cracks. Poor road conditions like muddy or gravel surfaces increase friction, and improper tire pressure settings can damage the tire surface. Storage methods also matter—parking in corrosive environments or oily areas makes tires brittle. High-performance modified tires may wear faster and have a higher risk of cracking. The solution? Install a tire pressure monitoring system for real-time alerts to prevent accidents. Overall, prevention is better than repair; regular tire cleaning and rotation are basic maintenance steps.
