What Causes Cracks in Tire Tread Patterns?

[McIsaac]

Tire tread patterns develop cracks for the following reasons: Aggressive driving by the owner: Frequent squeezing or scraping during parking, such as when the owner parks next to concrete blocks near green belts, causing the tire to press against or scrape against hard objects. This can lead to damage to the inner layers of the tire under heavy pressure. Inappropriate tire pressure: For example, prolonged driving with low tire pressure, especially on poor road conditions, can accelerate tire aging and cracking. Normal tire aging: This condition generally occurs when tires are exposed to prolonged sunlight, high temperatures, and other harsh environments. Continued use may lead to tire blowouts and other accidents.

After driving for so many years, cracks on tires are quite common, usually caused by tire aging. The rubber hardens and becomes brittle over time and with sun exposure, especially when parked outside under strong UV rays, making it prone to cracking. Additionally, after five or six years of use, tires naturally reach the end of their lifespan and should be replaced. Incorrect tire pressure can also lead to cracks—both overinflation and underinflation stress the tires. Road abrasions or chemical corrosion can turn small cracks into big problems. Don’t underestimate these cracks; a sudden blowout could be dangerous. I recommend getting them checked at a shop immediately and replacing them if necessary. Safe driving is far more important than saving money. Regular maintenance, like monitoring tire pressure and parking in the shade, can extend tire life.

I often enjoy road trips and have seen plenty of tire cracking issues. The core reason is the long-term aging of rubber under high temperatures, such as leaving the car parked in an open-air parking lot for too long under direct sunlight, which causes cracks to appear. High tire usage, frequent long-distance driving, or rough roads also accelerate wear and trigger small cracks. Unstable tire pressure is another hidden culprit—fluctuations cause uneven pressure distribution. I've encountered several instances where unchecked tire pressure led to crack propagation. Don't wait for a major issue to regret it—once cracks are spotted, get a professional evaluation and replacement as soon as possible. Develop habits like monthly tire pressure checks with a gauge and parking in shaded areas. These small actions can prevent problems before they arise.

As a family driver, I pay special attention to tire cracks because they can cause blowouts while driving, threatening the safety of my family. Tire cracks are usually caused by aging or exposure to sunlight, especially when the rubber loses elasticity after more than six years; abnormal tire pressure, chemical contamination, or sudden braking can also accelerate crack formation. Don't delay if you notice them—promptly visit a repair shop for inspection and replacement. Preventing potential risks is the top priority, and regular tire maintenance can reduce such issues.
