What Causes Tire Cracking?

[OWalter]

Tire cracking is primarily caused by external damage-induced cracking and aging-related cracking. Here are the specific details: 1. External damage-induced cracking: This type of cracking typically occurs in irregular locations, shapes, and sizes, resulting from collisions, compressions, or scrapes with foreign objects while driving. Some cracks only affect the rubber surface, while others may damage the tire's carcass cords, with severe cases leading to sudden tire deflation. Generally, minor surface cracks that only affect the rubber do not impact tire safety and can continue to be used. However, if the cracks penetrate deep into the carcass cords or cause cord damage, they pose a safety hazard and must be replaced as soon as possible. 2. Aging-related cracking: This type of cracking usually occurs in the later stages of tire usage, commonly seen on the tire shoulders or lower sidewalls, and sometimes at the base of tread grooves. It 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 typically does not affect the tire's service life or safety performance, and early replacement is generally unnecessary.

I've been driving for half my life and have seen too many tire cracking issues. The most common is aging - over time, tire rubber becomes brittle and hard, especially when parked outdoors under sun exposure or after enduring many summers and winters, cracks gradually appear. Underinflation is also extremely dangerous; I often see fellow drivers neglecting tire pressure checks, resulting in excessive flexing during low-pressure operation that develops small cracks into major problems. External damage like hitting potholes or curbs can cause immediate terrifying cracks. Don't take safety lightly - cracked tires have high blowout risks on highways, don't wait for accidents to regret. Monthly pressure checks and parking in shade effectively prevent issues. Overloading also damages tires severely - packing too much stuff accelerates crack formation. Preventive measures are crucial: consider replacing tires after about five years, don't risk lives to save money.

As an ordinary car owner, I get really nervous when I notice tire cracks. The main cause is rubber aging—my car is parked in an open space exposed to sunlight all day, and within a year, the tires show signs of aging cracks. I’ve also had issues with tire pressure; once, I forgot to inflate them before a trip, and the low pressure caused small cracks on the tire sidewalls. Climate plays a role too—rubber hardens in cold winters, making it more prone to cracking, while summer heat accelerates degradation. For prevention, I’ve learned to check the tire pressure monthly using a gauge and maintain the recommended value. Parking under shade or in a garage also helps extend tire life. If you spot a crack, don’t delay—replace the tire at a professional shop immediately, as safety comes first. A bonus tip: avoid sudden acceleration or braking, and watch out for hitting obstacles, as impacts can cause cracks. Taking good care of your car saves money and hassle.

Tire cracking can stem from various causes. Aging is the fundamental factor, as rubber materials degrade and become brittle over time due to UV exposure; insufficient tire pressure leads to internal stress, causing deformation and crack propagation; external mechanical damage such as hitting curbs or stones lodged in the tread can harm the tire; overloading results in excessive heat buildup; improper storage, like prolonged parking, accelerates deterioration. Maintaining correct tire pressure is crucial, and avoiding overloading reduces risks. For prevention, conduct regular inspections and replace tires promptly upon detecting issues to ensure safe driving.

For household car owners, tire cracks are often caused by daily negligence. Parking outdoors exposed to sun and rain accelerates rubber aging, leading to cracks. I've found that tire pressure issues are a common misconception, as failing to check it regularly can cause tire deformation and cracking. Additionally, overloading increases the burden on tires, resulting in cracks. Maintenance advice is simple: check tire pressure monthly to ensure it's within the range recommended in the car manual, and clean tire surfaces to prevent corrosion. When parking, try to choose shaded areas to avoid sun damage. Don't underestimate small cracks, as they can develop into major issues. Before driving, take a moment to inspect the tire sides for any abnormalities and address them promptly for safety. The recommended tire replacement cycle is five to six years, depending on mileage conditions.
