What Are the Causes of Tire Cracks?

[DiKarter]

Tire cracks can be attributed to the following reasons and solutions: 1. External damage causing tire cracking: This type of cracking usually occurs randomly in terms of location, shape, and size, resulting from collisions, compressions, or scrapes with foreign objects during driving. Some cracks only appear on the rubber surface, while others may damage the tire's carcass cords, leading to sudden deflation in severe cases. Solution: If the crack reaches the carcass cords, the tire needs to be replaced. 2. Aging and cracking: This type of cracking typically occurs in the later stages of tire usage, often seen on the shoulder or lower sidewall areas, and sometimes at the bottom of tread grooves. It is a natural change caused by long-term flexing and heat generation in the tire rubber. Driving with consistently low tire pressure can accelerate this process. Solution: Replace the aged tires.

I find that tire cracks are quite common, mainly due to the natural aging of rubber over time. Direct sunlight can accelerate the hardening and cracking process—just think about the consequences of parking outdoors overnight. Low tire pressure is another issue, as excessive bending of the rubber can accumulate stress and lead to cracks. Driving on rough roads, such as those with gravel or potholes, can cause scratches that develop into small cracks. Chemical substances like oil stains or cleaning agents spilled on the tires can corrode the surface. Improper storage, like leaving the car unused in a garage for long periods, can cause the rubber to dry out and shrink, leading to cracks. Make it a habit to check the sidewalls and tread during every car wash. If you spot any cracks, replace the tire immediately—otherwise, driving at high speeds can be dangerous, risking a blowout.

When inspecting tires, cracks are primarily caused by aging and external factors. Exposure to air and sunlight oxidizes the rubber, making it brittle, with ultraviolet rays accelerating this process. Abnormal tire pressure, whether too low or too high, makes the rubber prone to cracking. Driving habits also play a role—sudden braking or frequent driving on gravel roads increases wear, leading to micro-cracks. Large fluctuations in environmental temperature can cause thermal expansion and contraction, potentially resulting in cracks. Chemical corrosion, such as parking on oil-stained surfaces or absorbing contaminants after rain, can also degrade the tires. It is recommended to develop a habit of checking tire pressure monthly with a gauge, parking in shaded areas to extend lifespan, and consulting a professional for tire replacement when necessary.

Tire cracks can result from various causes: first, prolonged use leads to rubber aging and hardening, causing natural cracking; second, UV exposure from sunlight damages the rubber structure; third, improper tire pressure, such as low pressure causing excessive deformation; fourth, poor road conditions leading to cuts from sharp objects; fifth, chemical exposure like oil stains corroding the surface; sixth, manufacturing defects where even new tires may have cracks. All these factors require attention, and regular maintenance can help prevent them.
